Bigger. Bolder. Brighter. The Garmin Descent X50i is the ultimate dive computer for those ready to explore the depths with confidence and style. Featuring Garmin’s largest-ever 3-inch vibrant color touchscreen, it delivers your dive stats in stunning detail. The intuitive display ensures critical data, such as the projected ascent dive profile and in-dive depth chart, is visible at a glance, while the responsive touchscreen makes setup effortless above the surface.

Unparalleled Features for Every Dive

The Descent X50i is built to meet the demands of technical and recreational divers alike. Its rugged sapphire lens, leakproof metal buttons, and integrated dive light make it a dependable companion for even the most challenging dives. Rated to 20 ATM, it’s ready to venture to new depths with you.

With Subwave™ sonar technology, this dive computer lets you communicate with other divers up to 30 meters away, monitor up to 8 tanks for pressure, depth, and distance, and exchange preset messages — adding a new layer of safety and teamwork to your dives. Paired with optional Descent™ T2 transceivers, air integration becomes seamless, making tank monitoring more efficient than ever.

Plan and Navigate Like a Pro

The preloaded Diveview™ maps, featuring bathymetric depth contours for over 4,000 dive sites worldwide, make it easy to plan your next underwater adventure. With Garmin’s surface GPS and TopoActive maps, you’ll track your entry and exit points and always hit your target dive site. Meanwhile, the advanced ascent dive profile and decompression tools ensure safe and controlled ascents, giving you confidence throughout your journey.

Performance and Convenience Combined

The Descent X50i includes customisable dive modes, depth history tracking, and the ability to store up to 200 dives, all of which can be synced and shared through the Garmin Dive™ app. Built-in ABC sensors and an underwater compass provide unmatched navigation tools, and tide data keeps you informed of ocean conditions in real time when paired with a compatible smartphone.

Whether you’re exploring wrecks, navigating reefs, or taking on deep technical dives, the Descent X50i is designed to elevate your underwater experience. Dive smarter, plan better, and stay connected — because the ocean waits for no one.
