Setting Altimeter vs Barometer

By ATM Ranked #309 - Altimeters December 8, 2006

As a follow-up to the review posted by Schott5504, setting the Barometer is less accurate than setting the altimeter to a known elevation. Most NWS barometer readings are ~30min old, and the barometer can change enough in 30 min to affect the accuracy of the altimeter. Since the altimeter and barometer work together, i've found that setting the altimeter to a known altitude (http://geonames.usgs.gov/pls/gnispublic/f?p=151:1:7302452860451648895::NO:::) is a much more accurate way to calibrate this watch. Setting the correct real altitude will also auto-adjust the MSL Barometer reading as the local barometer reading is determined by the watch and should not be adjusted. Great watch overall!
