how accurate and sensitive is barometer?

Hi Robbie, this watch is a little less accurate then some others with a altimeter resolution of only 5 meters (determined from the barometer). The barometer has a resolution of millibar, so small changes in atmospheric conditions/weather can be tracked easily. All of these instruments have an inherent drift and a rule of thumb is ~ +/- 60 meters depending on the weather changes and how much elevation changing you have done. To keep it as accurate as possible always calibrate to references around you; i.e. summit markers, GPS, etc...
