Frequently Asked Questions?

What is the Dive Readiness feature?

Dive Readiness analyzes biometric inputs - sleep quality, exercise load, heart rate variability, and stress - to give you a personalized readiness score before each dive, helping you make informed go/no-go decisions.

How does the Mk3 43mm differ from the Mk3i 43mm?

The Mk3i adds SubWave sonar for diver-to-diver messaging (up to 30 m), native air integration via the T2 transceiver (up to 8 divers' tanks), and a built-in LED flashlight. The standard Mk3 lacks these features.

What maps are available on the Descent Mk3?

DiveView maps with bathymetric depth contour charts and a preloaded database of 4,000+ dive sites worldwide, helping you plan dives and navigate underwater terrain.

Can the Mk3 be worn as an everyday smartwatch?

Yes - GPS, wrist heart rate, sleep tracking, Body Battery, and 60+ sport profiles with ~14-day battery in watch mode make it practical for daily wear.
