Frequently asked questions about smartphone wind meters

What are anemometers for Android phone/iPhones used for?

People use smartphone anemometers for a variety of purposes. A person might use an anemometer for sailing, RC flying, windsurfing, kite flying, and any manner of other things. Wind speed meters are also used in various professional applications from HVAC testing (air conditioning/heating) to checking locations for wind farm appropriateness.

How do anemometers for smartphones work?

The phone + app anemometers on this list measure wind speed by calculating the rate that rotating elements spin in the wind. The faster the wind is blowing, the faster the cups or blades will spin. The rotations are counted and the wind speed is calculated as a result.

What’s better: an anemometer that connects to your smartphone physically or a Bluetooth anemometer?

This list includes both types of smartphone wind meters: those that are plugged into headphone jacks and those that connect wirelessly. There are two main differences: first, the Bluetooth models require their own internal battery. Second, the Bluetooth units tend to be more expensive.

There are reasons why a Bluetooth model may be more desirable in some cases however, such as when you want to be separate from the wind metering instrument itself (if you have it mounted on something), or if you have a new smartphone without a headphone jack it can be easier to just get a Bluetooth model than using a Lightning to headphone (or USB-C to headphone) adapter.

What is the absolute best iPhone anemometer attachment?

Naturally, as with anything, people’s preferences vary tremendously. But if you have an iPhone or Android phone with a headphone jack you might want to strongly consider the Vaavud models. If your smartphone doesn’t have a headphone jack, then the WeatherFlow Wind Meter (Bluetooth model) may be the best wind meter for smartphones.

I use a protective case on my smartphone, what do I do if these smartphone anemometer accessories don’t quite plug into it as a result?

This is a common problem among people who have Otterboxes or other chunky smartphone cases with thick protective plastic housings. Luckily you can get both flexible and firm headphone jack extenders which helps you plug in these anemometer smartphone dongles.

What is an Anemometer and What is it Used For?

How to make a cup anemometer (DIY paper cup anemometer) – Video

An anemometer measures wind speed and making a DIY anemometer out of cups is a great school science project. In this article we’re going to give you a step by step guide for how to make an anemometer with cups and straws and answer some questions you might have.

How to build a cup anemometer

This straightforward video shows you how to make an anemometer step by step. Below we’re going to repeat the steps and give you a little more detail on some of them. First, here’s what you will need:

Anemometer Ingredients

How to build an anemometer at home – Step by step guide

Step 1 – Use the sharpened pencil to poke a hole in the bottom of one of your dixie cups or another type of paper cup if you’re using easter egg cups for your DIY anemometer. Then use your hole-punch to punch two sets of 2 holes (four holes total) so that each hole is perpendicular to another hole. One set of holes should be closer to the top rim of the cup, and the other set of aligned holes should be lower down.

Step 6 – The cups should twirl in the air easily. To finish your anemometer, place the pencil into your empty plastic soda bottle for a base. You can use stickers or a marker to make an X on one of the four rotating cups which will make counting revolutions easier (it will be obvious how many times the red dot or X has turned around).

How to use your cup anemometer to measure wind speed

Have one person look at a stopwatch to see exactly how long ten seconds is. Use the following chart below to calculate roughly how fast the wind is blowing.

Alternatively you can “calibrate” your anemometer by driving exactly 10 miles per hour and seeing how many times your cups rotate when held out the window. However many revolutions are equivalent to wind blowing 10 miles per hour (assuming there is no additional wind blowing). Obviously you don’t want to be driving and sticking your arm out the window counting anemometer cup revolutions so you’ll need two people for this step.

Alternatives to DIY home-made anemometers

Several educational products are available if you don’t want to built an anemometer from paper cups. Here is an assortment of anemometer kits that you may find useful in your classroom. Click on an image to open the product in a new tab/window and check the price of these weather anemometer kits.

Of course if you’re reading this article because you’re interested in how to make anemometer for science project, you’re probably going to have to make one yourself using the DIY method outlined above instead of using a ready-built kit like these.

Frequently asked questions about cup counter anemometers

How does a cup anemometer work?

Cup anemometers are used by professionals to gauge wind speed. Normally anemometers will have built in computers that calculate how many revolutions they make per minute (or every 10 seconds or every 30 seconds, depending on how the computer is set up). The number of times that the wind pushes the cups around in a circle is then translated into the wind speed by the anemometer’s calculator into a unit like miles per hour, meters per second or whatever unit is desired. The more times the cups turn around in a circle, the faster the wind is blowing.

What is the difference between a 3 cup anemometer and a 4 cup anemometer?

Three cup anemometers are similar to four cup anemometers, they just simply have one less wind cup. For the purposes of this article about how to make an easy anemometer, we’re making a four cup model since that’s easier to make. Four cup models are also more common these days than 3 cup or 2 cup anemometers.

What is the cup anemometer working principle?

Cup anemometers feature a rotating array of wind cups that rotate as the wind blows. The faster the wind is blowing, the faster the cups will rotate. By measuring the number of cup rotations within a period of time (for instance within 30 seconds), we can calculate how fast the wind is blowing.

What other types of anemometers are there besides cup anemometers?

While this article is about how to make a kid friendly anemometer out of cups, there are several other types of wind guage instruments. Some examples include: hot wire anemometers (which measure how quickly a heated wire cools down in the breeze), ultrasonic anemometers (which transmit a sound signal to a reciever, measuring wind speed off of how long it takes to send it), and vane anemometers (which work on the cup principle but instead of rotating cups they have flat blades like a fan).

I don’t understand the instructions for how to make anemometer at home

Watch the “how to make anemometer video” at the top of this article for more information about how to build an anemometer out of cups for a school project.

I don’t want to use dixie cups, what else can I use for my homemade DIY anemometer cups?

Here are some ideas for how to make an anemometer with cups– using things other than dixie cups:

  • Colorful plastic egg shells – separated in half
  • Ping pong balls – sawed in half
  • Paper cups or condiment cups
  • Plastic soda bottles – sawed in half

Terms Defined / Anemometer Vocabulary

Anemometer An anemometer is a device that measures the speed of the wind. Anemometers are used by many professionals who work in the wind energy field as well as meteorologists/weather scientists, hobbyists and others. Different anemometers measure wind speed differently, depending on how they’re designed.

Cup anemometer A cup anemometer is a specific type of anemometer that measure wind speed by counting the number of rotations that a set of cups makes when the wind blows. Cup anemometers can be manual like the types of cup anemometers made of paper cups for science projects, or they can be electronic. Sophisticated cup anemometers can calculate the wind speed in units like miles per hour, meters per second or Knots (a naval unit of measurement for sailing). Simply put, the cup anemometer definition is: a wind speed gauge that uses rotating cups to measure wind speed.

Wind energy Wind energy is power created by the wind blowing.

Windmill A windmill harvests the power of the wind and translates it into energy. Early windmills pumped water or milled grains but today modern wind turbines generate electricity.

Wind farm A wind farm is an array of wind turbines in a windy area that all work together to harvest a large amount of wind power.

Wind/weather vane A weather vane or wind vane is a flat instrument which rotates. Depending on which direction it’s pointing, it will tell you which direction the wind is blowing in.

All about anemometers: what they are, how they’re used & much more

In this mega-FAQ we’re going to explain to you what anemometers are, who uses them, how they work, who invented them, and much, much more. Let’s begin!

What is an anemometer?

The simple answer to this question is an anemometer is a wind speed meter. There are different types of anemometers and they work in different ways but all anemometers have ways of measuring wind speed. Here are a few examples of what different types of anemometers look like (click any image to enlarge it in a new window).

As you can see, anemometers come in all sorts of shapes and sizes. Some are portable handheld anemometers and others are built in and affixed to buildings as a part of weather stations.

What is an anemometer used for?

what is an anemometer used for

An anemometer is for measuring wind speed. Some anemometers are built into larger, more complex weather stations which contain various other instruments and can provide weather forecasts based on a combination of all the data.

For instance an anemometer may be used to measure how windy it is before you go sailing on a sailboat. An air conditioning repair technician might use an anemometer to measure the output of a unit they are troubleshooting. A meteorologist might use anemometer data in their forecasts. A professional sports shooter might use an anemometer to calculate crosswind so they can compensate and hit a target from many hundreds of feet away. Storm chasers and weather hobbyists might use anemometers to understand how fast the wind is blowing. A wind turbine surveyor may use a handheld portable anemometer to determine if a particular area would be a good location to harvest wind power from.

What is an anemometer and how does it work?

An anemometer measures wind speed. Most anemometers work by counting the number of revolutions that their circular array of cups or windmill or blades make within a period of time (say, a 10 second interval) to see how fast the wind is blowing. It can then translate that measurement into a calculation of wind speed in units like miles per hour, kilometers per hour, meters per second or in the case of sailing applications, Knots.

What is an anemometer unit of measurement?

Anemometers measure wind speed in a variety of units. Generally speaking, the more expensive and sophisticated the anemometer is, the more units of measurement it will offer. Anemometer units of measurement may include:

  • MPH (miles per hour)
  • Km/H (kilometers per hour)
  • Knots (for sailing or windsurfing)
  • Feet per minute
  • Meters per second
  • Beaufort scale (a specialized wind speed measurement – read more on Wikipedia)

How does an anemometer work?

Most anemometers fall into one of two general categories: vane (or turbine) anemometers and cup anemometers. In both cases as the wind blows through them and moves their parts around in a circle, they count the number of revolutions per second (or per minute or per 30 seconds or whatever time period). By evaluating the speed of the rotations, the anemometer is able to calculate the wind speed in a common unit of measurement like miles or kilometers per hour.

There is also a third type of anemometer, a hot wire anemometer, which heats a component and then measures how quickly the component cools down (giving a reading of how fast the wind is blowing to cool it). A fourth, more rare type of anemometer is an ultrasonic anemometer, which we will explain below.

What is an ultrasonic anemometer and how do ultrasonic anemometers work?

Ultrasonic anemometers measure wind speed. They do this by sending a sound pulse back and forth from a transmitter to a receiver over a span of a few inches to calculate the speed of the wind blowing in between the two sensors. Ultrasonic anemometers are extremely specialized devices and they tend to be much more expensive than typical anemometers in the more common vane, cup or hot-wire types.

How much do anemometers cost?

Anemometers cost less money than you might think. You can get a portable handheld anemometer for under $20. Of course more sophisticated anemometers with lots of additional features and sensors can cost hundreds of dollars. (See our related article: The best wind meters for long range shooting for some more examples of anemometer cost range.)

How to use an anemometer / how to read an anemometer

In the case of electronic anemometers (most of them), normally you’ll just to turn on the unit and watch as it displays the current wind speed. You may decide to change the mode to view the wind speed in a different unit of measurement (i.e. kilometers per hour instead of miles per hour). In the case of manual cup anemometers for science class projects you’ll need to count the number of revolutions the cups make in a minute long period to calculate the wind speed.

How do you pronounce “anemometer”?

This video shows you how to pronounce anemometer:


How do cup anemometers work?

A cup anemometer (like the ones seen above– click on an image to open it larger in a new window) counts the number of times that the wind revolves a set of cups around in a circle over a period of time to calculate wind speed. At their most simple, cup anemometers consist of a stick of some kind that holds an array of 2, 3, or 4 wind cups which rotate. High school students will sometimes build anemometers or use simple non-electronic cup anemometers like the one below to manually count rotations over a period of 1 minute or 30 seconds to calculate wind speed.

How accurate is an anemometer?

Different anemometers will have different levels of accuracy. Generally speaking the more expensive the unit the more accurate you can expect it to be (no surprise there!). A common handheld decent quality anemometer accuracy range is within ±3%. This means that if the wind is blowing at 20 miles per hour, the unit might register anywhere between 19.4 mph and 20.6 mph, so fairly accurate for most purposes. Specialized scientific anemometers such as ultrasonic anemometers may have even higher accuracy rates.

Where is an anemometer placed?

Anemometers come in two varieties; those that are handheld and portable and those that are mounted in a single fixed location. For the most accurate readings, anemometers are best placed in locations that are unencumbered by obstacles so you can get a wind speed reading that isn’t blocked by trees/buildings/etc. For instance, the absolute worst spot for an anemometer would be directly next to a building or wall. Anemometers are sometimes mounted atop poles in the middle of yards, on top of buildings or in wide open spaces.

Does anemometer measure wind direction?

Anemometers measure wind speed. Some anemometers will also calculate the direction that the wind is blowing. These anemometers will often rotate or have an additional vane attachment that detects the wind direction. So to answer the question “Does anemometer measure wind direction?” we can say that most measure direction (they measure speed only), don’t but some higher end, more expensive models measure both speed and direction.

How is an anemometer different from a windsock?

Windsocks are a very simple way to gauge “is the wind blowing?” and “is the wind blowing fast or slow?” at a glance. But anemometers are very sophisticated instruments that can tell you precisely how fast or slow the wind is blowing, and sometimes even which direction the wind is blowing from. Anemometers will sometimes also be built into a feature-rich weather station which measures other factors like temperature, humidity and barometric pressure.

what does an anemometer look like / how does an anemometer look?

Here are some examples of what different types of anemometers (wind speed meters) look like. Click on any image to open it in a new tab and learn more about it.

How is an anemometer used / how is an anemometer helpful?

Anemometers, which measure wind speed, are used by many people for a variety of purposes. Knowing the wind speed is helpful to sailors, windsurfers, air conditioning repair technicians, professional sports shooters who need to know crosswind, meteorologists, and weather enthusiasts. Sometimes anemometers are built into sophisticated pieces of equipment with many other sensors called personal weather stations which are used by people who live in remote areas or microclimates where traditional weather forecasts are inaccurate.

How do anemometers work / how do anemometers measure wind speed?

Most anemometers have some sort of moving part which rotates or cycles in the wind so when the wind blows faster it will rotate faster. The anemometer’s computer counts the number of revolutions per second or minute (or whatever interval) and then figures out what the speed of the wind is in miles per hour, meters per second or whichever unit it’s set up to read. If you’re interested in learning more about how anemometers calculate wind speed, read on at Wikipedia.

Who invented the anemometer first?

Italian Renaissance man Leon Battista Alberti is credited with inventing the first anemometer, or wind speed meter, around the year 1450. Later in 1846 the English astronomer Thomas Romney Robinson invented the first cup anemometer. You can learn more about the history of the anemometer on Wikipedia.

Who invented the hot wire anemometer?

The first constant-current wire anemometer for practical use was created in 1909 by Russian scientist Dimitri Riabouchinsky (more info).

What does an anemometer and weather vane measure?

An anemometer measures wind speed. A weather vane measures the direction that the wind is blowing (for example, north-south or east-west).

How does an anemometer help meteorologist / why is a anemometer important to weather forecasting?

Basically what anemometers do is they tell you how fast the wind is blowing. If you’re interested in how an anemometer is used to measure weather, check out this answer from an engineer:

Meteorologists use anemometers to measure wind speed. Wind speed is obviously a weather feature reported in itself, but meteorologists use the data for other reasons as well. Gathering wind speed and direction at many locations and altitudes allows meteorologists to create the weather maps used to predict weather across the world several days ahead.

How does anemometer indicate the speed of the wind?

Most anemometers count the rotation of a series of cups or vanes to see how fast the wind is blowing. The faster the wind is, the faster the cups will rotate in the wind (or the faster its turbine will rotate). That speed is then calculated by the anemometer and displayed in a unit like miles per hour or meters per second on the display. In the case of an old fashioned manual cup anemometer, high school science students will often count the number of rotations and calculate how fast the wind is blowing based on that. See below for a simple cup anemometer example:

What is an anemometer used for in science?

What does an anemometer tell us? It tells us how fast the wind is blowing. This may be useful for a variety of different scientists. For instance, meteorologists use anemometers to calculate wind patterns. Renewable energy scientists and engineers may use handheld anemometers to figure out whether a particular place is a good spot for a wind turbine. Other scientists testing lab equipment may have different specialized uses for anemometers. So, what does an anemometer help scientists measure? Wind speed (or air flow, when indoors).

An anemometer is a gauge used for recording the speed of what?

Anemometers measure wind speed. Some very sophisticated anemometers and weather stations can also calculate the direction that the wind is blowing in, in addition to the speed at which it’s blowing.

How big is an anemometer?

Some anemometers are portable and can be held in your hand and stowed in a pocket. Others are part of a larger weather station and can be mounted on the rooftops of buildings or on poles in big open fields. The size of anemometers really varries widely depending on how it’s meant to be used.

How is an anemometer different from a weather vane?

A weather vane measures the direction that the wind is blowing. You frequently see them atop old houses or sometimes in people’s yards, ornamentally. An anemometer on the other hand is usually an electric device that measures the speed that the wind is blowing, based off of how fast a set of cups or a turbine is rotating. Anemometers come in both handheld and stationary mounted varieties. Some anemometers measure the wind direction as the speed, while others measure only the wind force.

What is an Anemometer and What is it Used For?

The Best Emergency Two Way Radios

Two way radios, sometimes also called walkie talkies, are extremely useful for a variety of purposes both in emergency situations and with large families at ski resorts or in a variety of work situations where cell phones are not ideal, such as farms.

Our picks for the best emergency 2 way radios:

Midland 22-Channel Two Way Emergency Radio

Midland is a well known maker of two way and emergency radios and their LXT500VP3 radio system is one of the best emergency two way radios for the money. This package includes two 22 channel radios and a dual unit charging base station (allowing both radios to be charged simultaneously). The 2 way radios can be powered either by rechargeable battery packs (included) or four AAA batteries.

BaoFeng BF-F8HP Two Way Radio

If you need a seriously long range two way radio with professional grade features, this might be the unit for you. The BaoFeng F8HP works with 128 channels and is compatible with walkie talkie frequencies as well as an expanded range of UHF and VHF frequencies. It even can receive weather channels. It’s also one of the best emergency two way radios for the money because it has an LED flashlight built in (which can also be set to serve as a blinking beacon which lets you locate the walkie, or allows others to see your location in the dark if you’re wearing or holding it). Note that without a HAM radio license, transmitting on UHF and VHF frequencies is only permitted in an emergency. This unit includes a high gain antenna, an optional belt clip, an earpiece/microphone headset, and drop in cradle charger.

Range: Unlisted, but some users routinely get 15 miles
Channels: 128
Battery: Up to 24 hours

Frequently asked questions about emergency two way radios

If I purchase multiple sets of the same radio, can I use them all together?

Absolutely, yes. The main thing is to make sure that all your two way radios are tuned to the same channel. It does not matter how many radio sets you are using: 20 walkie talkies will communicate just as well as two will.

Can multiple different brands of two way radios work together?

For consumer class two way radios with 22 channels, the answer is usually yes. More expensive professional class radios may operate at exotic frequencies however, making them incompatible with other brands sometimes. The two way emergency radios listed in this article with 22 channels will most likely work with each other, across brand.

Do these emergency two way radios require a HAM radio license?

If you’re using a consumer grade 22 channel two way radio, you don’t need any special license.

If however you’re using a UHF/VHF professional grade two way radio, you need a HAM radio license (unless you’re using it in an emergency scenario). The only radio on this list that broadcasts in these pro frequencies is the last one. You can learn more about obtaining your own HAM radio license at, which prepares you to take the 30 question multiple choice amateur radio exam to get licensed.

Can these two way radios receive CB radio transmissions from trucks on the highway?

Generally no. CB radios in trucks use different frequency ranges.

How many miles in range can I reasonably expect to achieve with these two way radios?

Although all walkie talkies advertise ranges of “up to 20 miles” etc in realistic practice, your range will be much smaller. The ideal case would be if the transmitting radio was on top of a mountain and the receiving radio was in the valley. On flat ground with building or hills in between, you may realistically be able to expect closer to a 2-5 mile range with family style two way radios. With that said, the advertised ranges are helpful when comparing units to each other because in relative terms they give you a sense of generally how strong or weak their transmitters are.

Can I get hands free headsets to use with these two way radios?

Yes, to find a handsfree headset compatible with your choice of radio, simply search in Amazon for the model number and the word headset. In many cases there are both original manufacturer headsets as well as third party headsets which offer different configurations, styles and sometimes lower prices than the first party manufacturer.

These two way emergency radios come with rechargeable battery packs and they also work with AAs, what is the difference?

Besides not having to replace AA or AAA batteries, there are two main differences between using your walkie talkie’s rechargeable battery pack and normal alkaline batteries. The first difference is that alkaline AA or AAA batteries will give you a longer battery life, sometimes as much as 10 hours longer than rechargeable batteries. The second difference is that if you’re using AAs you can simply replace your old batteries with fresh ones, whereas if you only use the included rechargeable battery pack you’ll need to charge your walkie to use it again, which can often take a few hours.

Can a walkie talkie be used while it’s in its charging cradle?

Generally yes, although it may be awkward to press the talk button while it’s sitting in a charging cradle.

Can other people listen in on my walkie talkie conversations?

Yes. Walkie talkies don’t prevent anyone else with a similar unit from tuning in to your conversations. At the same time, depending on where you are the chances of that may be rather low.

Some higher end walkie talkies like a few on this list have so-called “privacy codes.” These codes do not prevent other people from listening in if they have a two way radio tuned to the same frequency as you, but instead they limit your radio from receiving transmissions on whatever channel you’re using, unless the transmitting radio is also tuned to that same privacy code.

The best wind meters for long range shooting

Using a wind meter for long range shooting can be extremely helpful for predicting shot placement and compensating for cross wind conditions. Some high end wind gauges for shooting even have special applied ballistics functions that help you make calculations for shooting in the wind. There is a wide variety of shooting wind meters available today, and so helps to know the differences between them when you’re picking one out. We’ve done a round up of our favorite wind meters for shooting below.

The best wind meters for long range shooting

Caldwell Crosswind Professional Wind Meter

This Caldwell brand wind meter for shooting is a rugged and water resistant unit with an easy to read screen and a 90 degree rotating anemometer head (wind turbine). The head of this unit rotates 90 degrees clockwise but the meter measures wind speed in either direction (so there is no need to rotate it the other way). Measures: current wind speed, average wind speed, max wind gust, temperature, barometric pressure, and altitude/density altitude. This budget-priced unit provides a decent wind reading for long range shooting, especially for the money.

One especially nice feature of this wind meter for shooting is that it has a standard size screw mount at the bottom, so you can set it on a small tripod. Unit runs off a single coin style battery (included).

WeatherFlow Precision Shooting Wind Gauge

The free BallisticsARC iPhone and Android app allows to to calculate a variety of ballistics information when you used with this shooting wind meter wirelessly over Bluetooth (a non-bluetooth version that plugs into your phone’s headphone jack is also available, although it is missing a few features).

This unit provides a variety of data for shooting in the wind: wind speed & direction, temperature, dew point, heat index and wind chill, as well as density altitude and relative humidity. The BallisticsARC app also comes in a professional version (for $15) which gives you satellite imagery to provide a GPS rangefinder. See below for a screenshot of what this looks like in practice:

Kestrel Elite Weather Meter with Applied Ballistics

The Kestrel Elite Weather Meter is in some ways the gold standard for wind meter shooting. It provides you with Kestrel’s industry-leading Applied Ballistics Elite Ballistics solver, and the ability to store up to 30 custom gun profiles and has a library of custom drag models for over 400 bullets. This model is ideal for sports shooters doing competitive long range shooting because it even has a privacy PIN code for Bluetooth (if you’re linking it up with an app).

If you want a standalone tripod that rotates as the wind changes direction, you can combine it with a rotating vane mount and tripod.

This unit is also rugged, drop-tested and floats. Available with and without Bluetooth, in four different color options. Runs off of one AA batteries (included). Comes with a protective pouch, neck lanyard and a 5 year warranty. Made in the USA.

For a more budget friendly option for reading the wind for shooting, check out the Kestrel Sportsman Weather Meter, the younger brother model to the Elite. It is able to store less custom information but it comes with the tripod, Bluetooth, and vane mount. Measures wind direction, speed, crosswind, humidity, pressure, altitude, temperature and more.

Bushnell 202540KC Elite 1 Mile Conx Laser Rangefinder with Kestrel Sportsman

This two pack includes both a Kestrel shooting wind meter, and a Bushnell Elite 1 Mile Conx laser rangefinder. Together they form a powerful duo giving you extreme accuracy under even challenging wind conditions. Both the Kestrel anemometer for shooting and the Bushnell Conx communicate wirelessly to iPhone and Android devices with the included apps to analyze conditions so you don’t have to do manual calculation or data input.

With this wind meter for long range shooting, you can create custom ballistic curves on your phone with data from the rangefinder and calculate how weather conditions and crosswinds will affect your shooting outcomes. With the ability to measure altitude, humidity and other weather conditions, as well as density altitude (a key metric for many shooters), this combo provides all you need to shoot more accurately than ever before taking cross winds into consideration, especially at long range.

Frequently asked questions about long range shooting wind meters

Which Kestrel for long range shooting?

In order to get a wind reading for long range shooting, we recommend choosing a model that includes applied ballistics functionality. Kestrel makes two models of long range shooting wind meters with applied ballistics: the Kestrel Elite and the Kestrel Sportsman. The Elite model has more functions and more memory for custom data, whereas the Sportsman has less (but also costs less).

What is the best wind meter for shooting?

On this page we’ve laid out several long range shooting wind meter options, but if we had to pick the absolute 100% most fully functioning one, it would have to be the Kestrel Elite Weather Meter with Applied Ballistics. Both this wind speed gauge’s features and its reputation as an industry standard speak for itself when it comes to wind meter shooting excellence. When you factor in budget however, there are plenty of other candidates for the best wind meter for long range shooting, which we’ve listed above.

What is the difference between the Kestrel Sportsman vs Elite for long range shooting?

Generally speaking the Kestrel Elite model has more memory banks for additional custom guns than the Kestrel Sportsman model has, and a more detailed ballistics display. Because the Kestrel ballistics solver calculates each combo of a gun and a bullet separately, having more data banks to store different combinations is quite useful (you can always overwrite on top of the memory banks but inputting the data is a bit cumbersome and slow).

Is it worth paying extra for a Bluetooth enabled Kestrel wind meter for shooting?

We’d say yes. If you’re going to be using an anemometer for long range shooting frequently or with a number of different gun/bullet combinations, it’s especially worthwhile. Not only does this mean you’re able to input combinations of bullets and guns more easily with a full sized phone keyboard (instead of the button combination on the Kestrel unit), it also has a nice display with additional information. If you do plan on using the iPhone or Android app with your Kestrel for long range shooting purposes, we recommend getting a wind vane and mount with it because holding both devices at once is awkward. Note that the app can store more rifle/load combinations than the Kestrel unit can, since your phone has more storage.

Rundown of the Best Weather Alert Radios [Reviews]

We’ve examined the top rated weather alert radios. Here’s our report of the best storm radios below.

Best Emergency Radio Reviews

Midland NOAA Weather and All Hazard Public Alert Certified Radio

The US weather experts at NOAA issue location-specific weather alerts using a protocol called the S.A.M.E. code and you can set this storm radio to receive only alerts affecting your area (it’s user programmable to include a larger region too; up to 25 counties!). You can set it to use whichever of three alert systems you prefer: a 90 decibel siren, a voice alert or a flashing LED light. Also works with three AA batteries as a backup in case your home loses power during a storm.

This weather radio works in both the US and Canada and provides safety alerts in three languages (English, Spanish and French). The Midland WR120 (this model) is one of the top rated weather alert radios, after having gotten a massive number of positive reviews. Also works as an alarm clock.

RunningSnail Solar Crank NOAA Weather Radio For Emergency

Here’s another one of the best weather radios that has a couple of unique features. It receives warnings on 7 NOAA weather channels and also receives AM and FM radio. It also has a built in flashlight and LED reading lamp and is waterproofed enough to work outdoors during rainy weather, making it a great all purpose and weather radio for camping trips.

Plus, it can be charged with USB power from a computer or USB power brick (like a cell phone charger), or AAA batteries or a hand crank or solar power with its built in solar panel for use outdoors! The built in solar panel is also adjustable so you can set an appropriate angle for use. This alone makes it one of the best emergency weather radio for preppers.

Midland Portable Emergency Weather Radio with S.A.M.E.

The Midland Portable Emergency Weather Radio is a great hybrid device that can either sit on a flat surface in its charging cradle or be carried around handheld on battery power. It uses NOAA’s SAME weather alert technology to give you only the weather alerts that are useful to your local area and it can be customized for up to 9 counties at once. It also uses Midland’s Weather Scan technology, which lets you scan the local area and latch on to whatever the strongest NOAA channel is automatically.

The Midland HH54VP2 receives information on nearby hurricanes, tornadoes, floods, ice storms and other weather events as well as civil emergency information about Amber Alerts, fires and chemical spills. The clear LED screen is backlit for use in the dark. This is one of the best weather alert radios for handheld use.

Frequently asked questions about storm radios

Can I tune a storm radio or emergency radio to a normal AM/FM radio station? Not every emergency radio has this feature; some weather radios only tune to weather radio stations. But in our weather alert radios reviews above we’ve included whether or not each model allows for AM/FM tuning. If in doubt, check the product listings themselves.

What are the important features to look for in a weather alert radio? It depends on what you’re using it for but we generally recommend looking for a weather radio that has multiple ways to power or charge it just in case you lose power. Many weather radios have the ability to charge from a built in hand crank and some may even include a built in solar panel (though in stormy weather this won’t be of much use). For some, it may be important to get a handheld weather radio which can fit into a pocket. We also recommend considering getting an emergency weather radio that has a way to charge a cell phone, as many of the models listed in these reviews have.

What kind of information will I get using a weather alert radio? A weather radio using the NOAA S.A.M.E. weather protocol alert system will broadcast alerts tailored to your specific area using a series of county-codes (many weather radios let you program in a range of county codes that are relevant to your area). Weather radios capable of receiving the 7 channels of NOAA broadcasts will also receive weather alerts. Some weather radios will also give you access to civil emergency information like Amber Alerts and information about other local emergencies such as chemical spills. Still other weather radios will also have AM/FM tuning for receiving normal radio broadcasts.

Factors to consider when choosing a handheld anemometer or handheld weather station

Does this anemometer measure more than just wind speed?

The most basic handheld anemometer will measure wind speed, temperature and probably nothing else. If your needs are limited to just that, then you can probably get away with a basic entry-level cheap handheld wind meter. But if there’s a chance you might need some more weather sensors such as barometric pressure or dew-point, then you might be more interested in a fully fledged portable weather station. Still other more advanced portable weather stations can offer analytical information like heat stress index, Beaufort scale equivalents, or windchill based on combining multiple measurements into one.

Will I be using this mobile anemometer near water or in rain?

Some handheld anemometers are waterproof and others even float. If you’re planning on bringing your wind speed meter on a boat or in adverse weather conditions, we recommend getting a portable anemometer that’s designed for that (such as the floating and waterproof Kestrel models listed on this page).

Do I need a detached instrument or is an all-integrated wind speed meter okay?

Some users who are interested in extremely precise humidity or temperature measurements will want to consider an anemometer with a jackknife design such as the Ambient Weather WM-5 listed on this page which has a flip-out display cover which you can hold on to instead of the unit itself so as to avoid from influencing the data collection with hand-sweat or body heat.

What type of weather conditions will I be using this handheld anemometer in?

If you’re a storm chaser that regularly finds themselves in high wind conditions then you might have more rugged needs than, say, an HVAC technician. Some anemometers are more rugged than others and can measure wind velocity up to almost a hundred miles per hour. Generally speaking the more expensive the anemometer, the faster the wind speed it should be able to read.

What is the price of this handheld anemometer?

Price is often a factor and the price range of handheld wind speed meters and portable weather stations ranges from a few dollars to several hundred. If you are planning on purchasing additional accessories such as tripods or other gear to use with your portable wind speed meter you’ll want to be sure to factor that price into the total purchase price of your system. Ultimately the best handheld anemometer is the one that’s right for you.

Do I need/want smartphone app compatibility for my handheld wind speed meter?

Some higher end wind speed meters such as the Kestrel models or WeatherFlow ones on this list offer the ability to connect your wind speed meter or weather station to your cell phone via iPhone or Android apps which you can download to provide in depth analysis of your hyperlocal weather conditions.

This Bluetooth connectivity can be useful for looking back at stored historical data (i.e. recognizing that a particular wind speed is the highest ever recorded, or what’s “normal” wind speed for a ventilator system). Handheld wind speed meters that work with your phone can also sometimes hook up to other third party apps like ballistics apps for shooters.

What are handheld weather stations or handheld anemometers used for?

There are a number of things that people use handheld anemometers, pocket weather stations and portable wind speed meters for. Generally speaking, these are grouped into several different categories by use type:

Pocket wind speed meters for firefighters – In some places wind speed and directionality can be a matter of life and death. It’s hard to think of a more critical use case for accurate wind speed meters or anemometers than firefighters battling a forest fire. Firefighters may use pocket weather stations to predict how conditions may change that impact the way that they fight wildfires as well as get a sense of where they may be able to safely be located while they’re fighting wide ranging fires.

As one firefighter says in the video above: “The reason [wind is] important to us, fires can create their own wind but they’re also driven by the wind that goes on within the weather. Increased winds will increase the veracity of the fire, changes in wind direction will change the direction that the fire’s going, so those are things that are important for us to know when we come on the scene and monitor for changes during event.” Relative humidity and temperature are also important weather factors for firefighters to monitor because humidity affects how quick nearby tinder is to catch fire.

Handheld anemometers for HVAC professionals – Contractors installing or maintaining heating, cooling and air conditioning units often find handheld anemometers useful because they’re a convenient pocket sized way to gauge how fast air is blowing, and whether a unit is faulty or not without having to rely on what it “feels” like.

Portable weather stations for hikers & backpackers – If you’re hiking in a microclimate or out in the middle of nowhere you may not have access to reliable weather data, especially at high altitudes. Carrying a pocket weather station with you can help produce accurate hyperlocal weather forecasts which can determine whether it’s important to seek shelter in the case of adverse weather conditions.

Handheld wind speed meters for model plane enthusiasts – Although pilots of large aircraft can usually rely on other sources of weather data, model plane and drone pilots often find handheld wind speed and direction meters invaluable when determining their own hyper-local flying conditions.

anemometers and wind speed meters for sailing

Portable anemometers for sailing – Large sailboats sometimes have anemometers (wind speed and direction meters) built-in but smaller boats don’t have these and it’s often handy to be able to check wind speed with a handheld device.

Anemometers for sports shooters & hunters – For sports shooters, wind speed and directional information can be quite useful to boost the accuracy of their shots. While hunters are interested in accuracy they may also be even more interested in the direction of the wind for scent purposes (hunting upwind, etc). Read more about the effect of wind speed and direction as well as scents in hunting in this article.

Weather stations & barometric pressure meters for fishing – Fishers also sometimes use pocket weather stations to measure barometric pressure which fish react to. In high or low barometric pressure environments fish swim slowly in deeper waters, while in falling pressure environments fish are more likely to be swimming near the surface and be ready to bite at any opportunity.

Wind speed meters for agricultural users – Farmers sometimes need to measure barn ventilation as well as temperature conditions for livestock purposes and so handheld portable wind speed meters are useful for them as well.

Wind speed meters for wind power professionals – People working in the rapidly expanding wind power energy sector often use handheld anemometers to measure wind speed at locations they’re considering putting in new wind turbines or windmills, as well as for measuring data when doing maintenance checkups to existing wind power sites.

Coaches and trainers who need handheld heat stress meters – Some coaches working with athletes outdoors during summer or winter may want to use a wind speed meter that has a built in heat stress meter to monitor weather conditions by synthesizing a combination of temperature, wind speed as well as humidity. This is useful to make sure athletes don’t over-exert themselves in challenging weather conditions while training. Some handheld wind speed meters such as Kestrel models offer this feature.

Pocket weather stations for storm chasers – Storm chasing is one of those hobbies that’s gaining popularity due to both cheaper equipment and the effects of climate change producing more extreme weather variations. Storm chasers often use pocket anemometers in conjunction with other gear to monitor current weather conditions and trends. Pocket anemometers allow storm chasers to measure weather conditions surrounding extreme weather events without fragile equipment, since most of these small devices are rugged and many are weatherproof and come with lanyards or hand straps.

Pocket wind speed meters for EMTs & public safety workers – Portable wind speed meters are also useful for emergency medical technicians (EMTs) and also public safety workers dealing with avalanche control, smoke coordination, forensics, hazmat/biohazard remediation, K9 handlers, dive rescue workers, search and rescue, and more.

Pocket weather stations for Weather enthusiasts – The weather hobbyist community is growing and as weather station gear has gotten more both more portable and more affordable, some weather enthusiasts are choosing to buy their own portable weather stations. Weather reports generally offer forecasts for a large area– sometimes many square miles, and will never be as precise as the information you can get from your own handheld weather station.

Of course there are plenty of other reasons why a person might want a handheld weather station that aren’t related to any of the use cases listed above. Whatever the reason that you’re looking to buy a pocket anemometer we hope you find this article useful.

Frequently asked questions about handheld anemometers

What is an anemometer?

An anemometer is a wind speed meter that captures measurements on air velocity. To learn more about these devices, read our article titled What is an Anemometer and What is it Used For?

Some anemometers are more complicated and offer other advanced features like humidity, temperature and barometric pressure. These are sometimes referred to as personal weather stations.

Are there other types of anemometers besides the fan/vane anemometers listed in this article?

Yes, another popular anemometer type that sometimes comes in a handheld version is a cup anemometer. Read our article on those for more: The Best Cup Anemometers & How Wind Cups Work

How do anemometers work?

The anemometers on this list have fans or “vanes” which rotate at a speed based on the wind velocity. The devices then measure how fast the wind vane or fan is turning and then translate that into the speed of the wind in units such as miles per hour, meters per second, knots, or other units.
