• Speaking to Paligap, apparently the Garmin's Auto Calibrate is a bad thing and should be disabled. Particularly on 500s and a little bit on the 800s.

  • Garmin kindly removed the option to turn auto zero off - on both the 500 and 800.

    I have an ammusing email chain with them about this.

  • I never upgraded my 800 above 2.5 firmware, because if it ain't broke, don't 'fix' it is a good thing to live by.
