Garmin fēnix 8 Dive Computer Review | Best Smartwatch for Divers?

The Garmin fēnix 8 isn’t just a dive computer — it’s a full-featured sports smartwatch built for life on land and underwater. In this review, Torben from Divein.com takes the fēnix 8 on liveaboards, pool sessions, open-water dives, and even into a dive chamber to see how it stacks up against other top contenders like the Garmin Mk3i, Garmin G1/G2, Suunto Ocean, and the Apple Watch Ultra.

We’ll break down how the fēnix 8 performs as a recreational dive computer with nitrox support, customizable dive screens, and a reliable Bühlmann ZHL-16C algorithm — and where it falls short with its 130-foot (40 m) depth limit and no air integration.

Beyond diving, we’ll also explore its sports tracking, GPS accuracy, health monitoring, and smartwatch features to see if this is the ultimate all-in-one watch for divers and athletes alike.
