Freediving guides for Garmin owners
You already own a capable dive watch. 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 — written by the maker of inDepth Apnea Blue and inDepth Apnea Pool.

The user guides are the practical ones — what to set before your first session, what every button does, and the handful of things that genuinely confuse people. Ten minutes each.
Which Garmin watches can actually read depth in a Connect IQ app
A dated, sourced table of measured Connect IQ depth ceilings on Fenix 5, 5 Plus, 7, 8 and Descent Mk2 / Mk3 — which read true depth, which clamp near 3 m, and which inDepth supports.

Budget freediving computers in 2026: what everything costs
Every wearable dive computer with a real apnea mode, priced and dated - Descent G1 to Mk3i, Suunto Ocean and D5, Shearwater, Apple Watch Ultra plus Oceanic+ - and the used-Garmin-and-free-app route that undercuts all of them.
Freediving surface intervals, explained
Why surface intervals matter, how hypoxic blackout risk builds across repeated dives, and the surface-rest models freedivers use — including the ones inDepth Apnea Blue implements on Garmin watches.
