How to use inDepth

Short, practical guides: what to set before your first session, what each button or screen does, and the handful of things that confuse people. Ten minutes each, not a manual you have to sit down with.

Training app: dry breath-hold training

Coaching, the exercise library, running a session and safety, all on your phone. No watch needed.

The phone app

Garmin watch apps: optional

Already have a Garmin? These three watch apps are a free add-on to the phone app, not required to train.

  • inDepth Blue: freediving & spearfishing

    Set-up, how deep your watch can read, a dive session start to finish, the buttons, depth alarms, surface-rest models and GPS spot marking.

  • inDepth Pool: dynamic apnea

    Set-up, a pool session start to finish, the button model that catches everyone out, automatic rep start and end, turn detection and countdown alerts.

  • inDepth Dry: dry breath-hold training

    Setting your max static, the four built-in sessions, a session start to finish, the buttons, marking contractions and what happens if you feel unwell.

Safety first. inDepth is a training aid, not a life-support device. No algorithm removes the risks of dry breath-hold training, pool apnea or freediving. Never train alone, always follow the one-up one-down rule, and treat every rest recommendation as a minimum.

Looking for something else?

  • Install help & FAQ: getting the watch apps onto your Garmin over USB, USB mode and MTP, manual sideloading.
  • Freediving guides: background reading rather than instructions. Which Garmin watches read depth, which one to buy, and how surface intervals work.
  • Support: when something is wrong and none of the above covers it.
