Dive mode: the watch $ucking always reverts to compass mode!

I’ve used the Mk1 for two liveaboards recently and I $ucking hate it so far.  While diving, the watch ALWAYS changes, on its own, to the compass mode.  I want the watch to stay in whichever mode I navigate to, which is mostly the standard depth/time/deco screen.  All I care about is the time to deco and I want the large font of that screen.  I do NOT want the compass mode.  While diving, the watch reverts to compass mode ALL the time.  I stopped counting at 20 times the first dive with this watch.  Imagine scrolling through the menus 20-30 times, PER DIVE, to get to the menu you want, four dives per day, for a week.  WTF, Garmin.  Have you ever scuba dived?  Please advise how to fix this.
