BTMETERHard Travel Case Bag Protect BT-100 Series Handheld Anemometer

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

Works great and gives different qind speeds ie, m/s kmh mph

It's pretty damn' accurate! I tried it as I walked in a flat calm and it recorded a definite wind speed....This little beauty will let you know if the wind will rip ypu off your board or tear your kite into pieces, or.... it will let you know if your beloved wake/foil board is just another floating chunk of whatever and your kite is just a pretty thing to look at as flops forlornly on the ground.Trust me on this.... my wife will kill me for saying that!... This is something that should be in every kite/foil/wake boards toolbox, and also,here's the rub, in every light aircraft pilot's toolbox as well. If you don't know just how strong (or light) the wind is, how safe are you?Happy flying!

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.

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.

I bought a previous one for £10 cheaper and it lasted only a year. This one is robust and has average wing setting. Perfect..
