Product review (3 stars): Testing WM-3 Handheld Weather Meter
Received my WM-3 last week but had no wind till a cold front moved through so waited till I could test the wind speed. During the front I ended up traveling to an Ag noaa weather station to try an calibrated the wind speed. My meter was showing 4.5 mph slower than the Ag station. It took several tries to get the wind speed calibrated but finally got it. Not sure why the wind speed can't be fairly accurate out of the box.
The unit is nice and small to handle but the belt carrier loop is too small for my western leather belts so I ended up just putting it in my shirt pocket. It will be a nice unit to carry in the tractor when I'm field spraying to keep track of the wind speed. Once I calibrated the humidity to my desk top station it has been fairly accurate.
I would like to see the buttons a bit further apart as my big fingers had a hard time pushing 2 buttons at the same time to calibrate.
