With dive mode, you will have multiple aspects of your dive analyzed and calculated.

If you opt to resubmerge and continue your excursion, the dive tracking resumes.

With the post-dive function, it engages three minutes after surfacing.

The logbook will be automatically closed, and the dive computer begins to display other metrics.

You'll be able to review your desaturation time, no-fly time, and surface interval.
