Review on Nikon 16144 Meter Spotting Scopes by Tyler Kota

Seems to be accurate although my blade is a bit heavy I'm not sure they all are. Easy to use, plug it into your headphone jack, launch the app and hold your phone in the wind. When I checked next to the weather station it was within a few miles per hour, I think the difference is that I'm on the ground and the readings are taken much higher off the ground. I use it with the WindMeter app so I can get data and then use it with Strelek Pro, much more options. I didn't bother with the Nikon app.
