The Descent X30 Dive Computer features a vibrant 2.4-inch display and a housing and bezel made with recycled ocean-bound plastics. With four large metal buttons, up to 30 hours of battery life and support for multiple dive profiles, it’s perfect for your next dive.
2.4-Inch Color Display & Flip-Screen Mode
See critical information and custom dive screens at a glance on a large, easy-to-read color display. Flip-screen mode orients the buttons on top, allowing navigation of up to three data fields per page, with large metal buttons that are easy to use even with gloves.
Multiple Dive Profiles & NDL Aware Depth Metrics
Supports single- and multi-gas dive profiles, including trimix, while NDL Aware depth metrics extend your bottom time by showing real-time impacts on your no-decompression limit (NDL) as depth changes.
Surface GPS, Compass & Dynamic Depth Chart
Mark surface entry and exit points with advanced satellite connectivity, navigate underwater with the 3-axis digital compass, and review depth history during dives to guide decompression and safe ascents.
Dive Bands, Dive Log & Garmin Dive App
Comfortable, durable hinged silicone bands fit over wetsuits and are compatible with 26 mm QuickFit bands. Store and review all dive data in the dive log and automatically sync and upload via the Garmin Dive app.
Water Thermometer, Surface Interval Tracking, Alerts & inReach Connectivity
Track water temperature to locate thermoclines, plan multiple dives safely with surface interval tracking, stay alert with audible and vibration notifications, and remotely trigger an SOS above the surface when paired with an inReach satellite communicator.
