I thought you actually meant "plane Dive" ... I flew internationally exactly 91 days ago. while I haven't dived underwater the Garmin has registered my plane trip as a dive! I like this feature, allows you to know Cabin Altitude and N2 loading, off gas over time as the flight continues. It assumes you have saturation dived at sea level, and have now "surfaced" to 8000 or so feet!! quite fun thank goodness it doesn't record it as a dive to the Dive App.
