The Garmin Descent X30 puts dive information on a 2.4-inch colour screen, with customisable data pages and four large metal buttons that can be used with gloves. It supports single-gas, multi-gas and gauge diving, with a digital compass for underwater navigation and surface GPS to record entry and exit points.
Features for planning and reviewing your dives
-
A display you can arrange around your dive: choose custom data screens with up to three fields per page, use the large-font option, or flip the screen to position the buttons above the display.
-
Air, nitrox and trimix support: configure one bottom gas and up to 11 decompression or backup gases. The computer uses the Bühlmann ZHL-16c decompression model with adjustable gradient factors.
-
Depth and decompression information: NDL Aware depth metrics show how changes in depth affect the no-decompression limit. A dynamic depth chart displays your depth history during the dive.
-
Navigation above and below the surface: surface GPS marks entry and exit locations; the three-axis digital compass provides heading information underwater. GPS positioning is for surface use only.
-
Audible and vibration alerts: receive dive alerts for ascent rate, gas switching and other monitored dive parameters, with custom alerts based on depth or time.
-
Dive logs in one place: store and review dives on the computer, then sync logs to the Garmin Dive app on a compatible paired smartphone.

Compatibility and care
The Descent X30 is compatible with 26 mm Garmin QuickFit bands, including the bungee mount. These optional accessories are separate from the supplied hinged silicone band.
Optional inReach connectivity can remotely trigger an SOS above the surface when the computer is paired with an inReach satellite communicator and dive case. The communicator and dive case are not included, and a satellite subscription is required. Satellite-device use may be restricted in some jurisdictions.
Use the supplied Garmin documentation for charging, operation and care instructions.
