I've been comparing my G-Shock Rangeman's Station Pressure and Temperature to that of my Kestrel Elites lately. It has been spot on with Station Pressure (weather I'm wearing it or not). Temperature has been within +/-2 degrees Fahrenheit after it has been taken off my wrist for ~10-15 minutes. Wouldn't hesitate to use it calculating a density altitude via a chart in the field. Just some Tuesday morning coffee on the porch thoughts.
