BTMETERBT-100 Handheld Anemometer, Digital Wind Speed CFM Meter Gauge Air Flow Velocity Tester for HVAC Shooting Drone, Wind Chill, 14℉-113℉ Wind Temperature

I picked up the BTMETER BT‑100 Handheld Anemometer recently for drone flights and my RV HVAC checks—and it's quickly become my go-to gadget.For anyone serious about wind data—drone pilots, HVAC DIYers, sailors, hobbyists—the BTMETER BT‑100 delivers pro-grade features in a compact package. Accurate, versatile, and user-friendly with an unbeatable price tag. It’s earned a permanent spot in my toolkit.

Great little guy with accurate information and easy to use.

Use it on my sailboat for backup wind readings and detecting airflow inside the cabin on hot days. The lighting is very useful for the nights where it's too dark to read. The display is good, and the battery life is phemonemal. It doesn't like speeds over 30kts of wind. Fits nicely in your hand and the attached lanyard helps a ton in windy precarious spots. Build quality is good, would love for it to be water resistant as measuring wind with rain still leaves something to be desired. In all a great product, and would buy again.

Works well. Good value.

Purchased for my husband for Christmas, he wanted a handheld digital wind speed meter - don't know why he wants to go stand out in a storm to read the wind, but that's just him! Anyway, he said it's easy to grip, provides good wind speed readings, easy to read - he said it is a good quality product...guess we are ready for hurricane season now!

Seems to be fairly accurate I use it to ✓ tte wind for my drone

Good little cheap unit. I can’t say it’s 100% accurate but it helped balance the airflow of the house after finding where the issues were. I just wish someone would make a meter where the display lighting stays on. This one shuts off after 4 seconds and when you’re in darker areas you need it lit up to see the readings. It shuts off before the readings are stable.

After installing the batteries (a small screwdriver was included as a thoughtful accessory) it took less time to begin using this device than it took you to read this sentence. Press the "on" button and it begins reading instantly.The buttons are intuitive. Press "max/min" once and you'll get the maximum wind speed. Press it again to get minimum wind speed. Press it again to go back to normal mode. Similarly, "Avg" gives you average speed over time.Really like that this comes with a protective case.The backlight is very bright - even in daylight it makes reading so much easier. It's also a must-have at night (for those like me who may use it in darkness for measuring potential windchill). Backlight turns off automatically after 15 seconds (presumably to save battery life).I tried to see if this has auto-off feature but after leaving it on for several minutes it doesn't turn off. This can be a good thing when measuring min/max/avg wind speed though.Booklet that comes with this device states ±5% accuracy, and it's rated to 65mph (plenty fast wind speed for almost all occasions). These are decent accuracy and speed ratings for this great price range.Because this is a "directional dependent" device, I recommend using a wind sock or similar method of knowing wind direction. Aligning this device with the wind direction gives best results.
