Answer the ocean’s call with Descent X30. This large-screen dive computer with a 2.4" vibrant colour display makes it easy to view critical information at a glance. Enjoy support for single and multi-gas dive profiles, including trimix.

Navigate below the surface with the 3-axis compass and maintain situational awareness with audible and vibration alerts. Extend your bottom time with NDL Aware depth metrics and see in real time how specific depth changes impact your no-decompression limit (NDL). Built for divers by divers, Descent X30 features a housing and bezel made with recycled ocean-bound plastics.

The rugged design features a 10 ATM dive rating and 4 large metal leakproof buttons. Use the surface GPS to navigate to dive sites and mark entry and exit points. Wirelessly upload your dive logs back on deck and review data from your dive in the Garmin Dive smartphone app. Plus, get up to 30 hours of battery life in dive mode so you can explore longer.

Key Features and Benefits
Large 2.4″ Colour Display
A vivid, easy-to-read screen ensures you can see critical dive data at a glance. Customisable layouts allow up to three data fields per page, making reading depth, NDL, or gas mix information effortless, even in low-light conditions.

Multi-Gas and Trimix Support
Supports single-gas, multi-gas, and Trimix dive profiles, accommodating both recreational and tecreational divers. Gas-switching features provide flexibility for extended dives without overcomplicating the interface.

Rugged, Dive-Ready Design
Built for challenging conditions with a 10 ATM (100 m) depth rating. Four large, leakproof metal buttons are easy to operate with gloves or thick wetsuits, and flip-screen mode lets you orient the device to suit your dive setup.

Surface GPS and Compass
Mark entry and exit points accurately and navigate underwater confidently with a 3-axis digital compass - particularly useful for low-visibility dives or unfamiliar locations.

NDL Aware™ Depth Metrics
Real-time insights into how depth changes affect your no-decompression limit (NDL) allow divers to extend bottom time safely and make smarter decisions underwater.

Environmental Awareness
An onboard water temperature sensor helps locate thermoclines and anticipate changes in dive conditions, supporting safer and more comfortable ascents.

Smart Alerts
Customisable audible and vibration alerts keep you aware of ascent rates, gas switches, decompression requirements, and safety stops, reducing cognitive load during critical moments.

Extended Battery Life
With up to 30 hours in dive mode, the X30 has the endurance to support multiple dives across a full trip, including high-brightness and night-dive settings.

Comfortable and Adaptable Bands
Hinged silicone straps fit easily over wetsuits, and compatibility with 26 mm QuickFit® bands provides flexibility for alternative straps or bungee mounts.

Dive Logging and Connectivity
Store dive data on the device and sync it to the Garmin Dive™ app for seamless logging and sharing. Pairing with inReach® satellite communicators (with a dive case) allows for SOS messaging above the surface.
