Alright, for anyone interested, Garmin did replace my Descent at no charge to me. The process was fairly painless. My new one has been working flawlessly since I received it, other than the odd ski run miscount from time to time. In dive mode, the compass has been working and I can now download my stored hr data with no issues. Now, if only we could get a max depth as data field somewhere...
Sorry that no one helped you with your questions, myself included. I must have missed this.
I 100% agree on being able to see your Max Depth during a dive, as every other dive computer does this, you’d think a $1000 computer would too. I suggested this months ago, so hopefully this extensive update that they’ve supposedly been working on since January, will include this beneficial data.
