Review on Wintact Handheld Anemometer Small Digital Vane Wind Speed Meter Gauge, Pocket Air Flow Velocity Tester With Measuring Wind Temperature 14℉ To 113℉ For House HVAC Duct Outdoor Kite Boat Sailing Surfing by Chad Guinn

No adjustments for temp or more importantly wind velocity. How hard would it have been to have a software adjustment using the two buttons or at the very least a trimmer pot in the back? Backlight only stays on for ten seconds. At night that make it a real pain in the ass to have to keep repeatedly pressing a button to see a reading in the dark. Have a constant on setting option for the backlight and power save. If I want to save power I'll turn it off. It also loses all settings when the battery is removed. Bought this to check relative wind speed before launching drones. Absolutely cannot trust the reading. I should not have to do a mental offset to this inaccurate device. I'll probably drop it from four hundred feet AGL to see how well it bounces. At least then it it will have had been useful for something.
