When I splash for the second dive, the Garmin will behave exactly as if I had had it set to GF50/80 from the beginning (before the first dive)?
I expect the answer is yes, but it sure would be nice to get confirmation from a Garmin developer or someone who talks to a developer....
After discussing it, I'm fairly certain the answer here is going to be yes. Unfortunately I haven't had a chance to do my second round of testing yet (after the full 24 hr SI)
Secondly, I have confirmed that the 'deco lockout' enabled/disabled setting does remain after the 24 hour lockout period expires.
