Garmin Descent™ X30 Dive Computer

Answer the ocean’s call with Garmin Descent™ X30 Dive Computer. This large-screen dive computer with a 2.4" vibrant colour display makes it easy to view critical information.

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 your dive data - such as depth and ascent profiles and more - in the Garmin Dive™ smartphone app.
