Digital Anemometer Handheld - BTMETER BT-100 Wind Speed Meter Gauge, Accurately Measure Wind Velocity Temperature Speed for CFM with MAX/MIN/AVG, Backlight LCD, HVAC

Does the job, tells me wind speed, need to test it with stronger wind, great little thing for my drone so I know when to fly it or not.

Simple, straightforward, includes batteries

It works. Checked against my Nav instruments. It needs to be kept in its case. The rotor could easily get damaged. It uses two standard AAA batteries. 👍 from me.

Excellent product

Small enough to always have in the rucksack, reads the same as much more expensive equipment

I am considering installing a small wind turbine at my property. I had a feasibility study done but it was difficult for the company to say for sure what wind speed I would get due to neighbouring properties/trees. Enter this anemometer to measure wind speeds at my property and send the data to my phone for analysis on averages etc. I chose it because it stated it could connect via bluetooth to an app and give regular data. The wind speed and temperature readings seem about accurate, but the device constantly powers off and disconnects from bluetooth even though I am well within 10 meters of the device. I have changed the settings in the app for it to not power off but it made no difference. In order to get average readings I am now forced to go to the anemometer and take a reading at the same time each day. It was actually meant to be attached to my chimney, obviously I can't climb the chimney every day so it's not really in the right place to get accurate measurements. I could have bought a much cheaper model if I knew I'd have to go and check it every day. Very frustrating.

Unfortunately as this review come through to my email.. We was starting to use this for the first time and unfortunately it failed to work after 2 min of use. Hopefully the supplier will see this and replace it or refund it

My only negative comment is the display.It's not easy to read without the backlight being on, especially the smaller text such as the Units selected.Otherwise it's a good thing to have when flying drones.A really nice touch was they included a small screwdriver to help open the battery compartment.
