Garmin Descent X30 Rugged Scuba Diving Computer with Vibrant 2.4" Color Display

Answer the ocean’s call with Descent X30. This large-screen dive computer with a 2.4" vibrant color 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.
