Guides
Freediving guides for Garmin owners
Chances are the watch on your wrist can already do a lot more underwater than you think. These guides cover which Garmin watches read depth, which one to buy for freediving in 2026, and how surface intervals keep you safe between dives. They're written by the people who make inDepth Apnea Blue and inDepth Apnea Pool.

The user guides are the hands-on ones: what to set up before your first session, what each button does, and the few things that tend to trip people up. Each takes about ten minutes to read.
