Proster Handheld Digital Anemometer - Portable Wind Speed Meter CFM Meter Wind Gauge Air Volume Measure with LCD Backlight for Outdoors Sailing Surfing Fishing

I fly drones every day. Accurate wind speed is very important to me because knowledge of the wind speed and the second to second variations in wind speed are allow me to decide how to safely pilot my drones without crashing them or having them be blown away.This device is very sensitive and accurate whether measuring a 1 mph breeze, or a 12 to 35 mph gust. I have now used it for 56 consecutive days of flight and the 9 Volt battery is still holding a strong charge.Size: 6.5" tall; 1.5" thick; and 3.5" at its widest. The handle is 2.5" wide and 1.25" thick. Has a nice case. Fits well in my flying bag. Fits well in my small man's hand. Feels good in the hand.Weight with batteries is 7 oz.Construction: solid impact resistant plastic with heavy duty rubber grip in handle part.Impeller blade: 8 blades which rotate freely with the slightest breath.Screen: 1-1/8 × 1-3/8 inches. LCD which is very easy to read. Backlight is easily clicked on for low light situations.Sounds: makes nice chirps when turned on and when functions are changed.Functions: Easily switched between all the functions. I only use it for measuring wind speed in mph or kilometers/hour. Also, measures in knots. There are other functions listed by seller, but I do not use them.In summary, I am impressed with the quality of the build, its reliability, its ease of use, the readability of the screen and its portability. I can't be without it.Good going on a fine product at a great price.

So far, happy with this instrument. Have not had it long but it is easy to use and is providing good wind speed measurements. The data is used for reference on the race committee boat at sailboat race events. It is light enough to stuff in a jacket pocket but it is not small so I'm talking about a big pocket. If it proves durable it will be a great value. The only nit pick is that it uses a 9v battery so need to have a spare on hand. Nothing I own uses 9v except this. It would also be nice if it recalled the last Unit when turned off instead of having to reset it each time. It probably saves battery by not having persistent memory but the Knots unit is the last one in the cycle so every use requires a bunch of button presses. Leaving it on is an option but that uses up the 9v battery more quickly that it's worth.

Works good, definitely feels cheap but it is cheap so no complaints

I got this anemometer for use in gaging wind events such as tropical systems, since I live in Florida. There was a problem trying to get the separate (but included) PAKKO battery in. It's 1/16” too long. A 9-volt Duracell battery fits perfectly, though.As far as reading the wind speed, I found the numeric result to be clear and easily readable. However, the units are much smaller and harder to read. I'll be using mph, which is found under the UNIT button. It has to be set each time the device is turned on again.This anemometer will work fine for my needs.

Great little instrument at an attractive price and exactly as advertised. I can't speak to its accuracy as I haven't tried to calibrate it. Given my application (kitesurfing), I'm not much interested in +-2% variations in true wind speed.The features that I appreciate are: easy of use: clear, legible LCD screen, backlight, easy one-handed operation, broad choice of wind speed units (MPH, KMH, KNOTS, m/s, ft/s, ft/min, mil/h). Also, the vane rotates with the slightest breeze and reads wind from both directions.

I got this for use in the garden and for help in siting a plastic greenhouse. There was a problem trying to get the separated but included PAKO/PAKKO (?) battery in. It turns out it was 1/16” too long. A 9v Kirkland battery fit perfectly, tho.As far as reading the result, the numeric result is clear. However the units are much smaller and some people might need a little magnification.I will be using mph, found under the UNIT button.I think it will work fine for my needs and also heavier usage.

Used ot for duct work in a darkroom. It's easy to use and actually displays cfm which is super convenient. In a not well lit room and at a certain angle, the display can be difficult to read with or without the backkight on. I'm assuming the results are accurate and precise but I don't have anything to compare it to. Overall, it seems like a decent cheaper anemometer.

Purchase this meter about three years ago and only used it approximately 3 to 4 times, and It has always been kept in the zipped case that came with a unit. The last two times I’ve used it if you lay it down on its back side on a vent to read the airflow, the fan blades stick, slow down, and makes a rubbing sound. But if you flip it face down on the vent it seems to move freely. But then you can’t read the data, (wind speed). Haven’t contacted the manufacturer yet but surprised with only using it a few times that this is happening already. It’s never been dropped or abused and has been kept in a safe place in the zipped case that came with the meter.
