Product review (5 stars): A real bargain.
I got the WM-3 last week and wanted to give it a decent test. I took it to a local airport and was pleasantly surprised that the readings matched high end equipment that is installed there. Then it was off to the beach. The WM-3 has quick response to wind speed measurements and was able to keep up with the gusts at the beach. Temperature and humidity were quick to respond. I have been working with weather equipment for over 15 years and this is the handiest handheld unit I have owned. Mine came with a lightweight case with loop that slid onto my belt. You could forget its there. The display is lighted  and shows up well in most light conditions. The auto shutoff feature is good also because I often forget to shut down equipment. I want to take it to the target range and try it out compensating for wind drift when distance shooting. I suspect this will end up in my trucks glove box as an all purpose device to keep at the ready.
