  • However, altimeter accuracy depends on correct calibration, which is achieved by periodically adjusting the pressure altitude in in the Kollsman window.

Ideally I’d like to see an option like Garmin’s to specify a minimum pace to auto-pause at. For multiple metrics you can chose the fields you want to display on a single screen, but you only get one screen.
