Ambient Weather WM-5 Overview

On a recent hiking trip, I had the chance to use the WM-5, and it’s like having a weather station right in your hand. This handy device from Ambient Weather isn’t just portable; it’s also designed with a pocket-knife style that tucks away when not in use, which I found to be a clever way to protect the unit.
