Description

The Garmin Descent X30 is a large-format dive computer built to show your essential dive data at a glance. Its vibrant 2.4-inch color display and four large, leakproof metal buttons are easy to read and easy to use, even with gloves on, and flip-screen mode lets you put the buttons on top.

The X30 supports single-gas and multi-gas dive profiles, including nitrox and trimix up to 100% O2, plus gauge mode, all running the Bühlmann ZHL-16C decompression model with gradient factors. NDL Aware depth metrics show in real time how a change in depth affects your no-decompression limit, and the dynamic depth chart shows your depth history and projected ascent plan.

On the surface, GPS marks your entry and exit points, and a 3-axis digital compass helps you navigate underwater. Audible and vibration alerts keep you aware, your dives sync to the Garmin Dive app, and setup sharing can sync gases, conservatism and alerts with a second compatible Descent dive computer used as a backup.

Battery life is up to 30 hours at the default medium brightness (up to 47 hours in night dive mode), and the housing and bezel are made with recycled ocean-bound plastics. The hinged silicone dive band fits easily over a wetsuit, and the X30 also takes 26 mm QuickFit bands, including the bungee mount.
