The Garmin Descent X30 dive computer offers a bright 2.4-inch color display, making it easy to read crucial information at a glance. Designed for divers, it supports both single and multi-gas dive profiles, including trimix, and features underwater navigation with a three-axis compass. Enhanced situational awareness is provided through audio and vibration alerts, while NDL Aware depth data allows for extended dive times. Crafted with 100% ocean-sourced plastic, the Descent X30 is environmentally friendly and features a 10 ATM water resistance rating. With surface GPS, divers can mark dive start and end points, and sync logs wirelessly to the Garmin Dive app for detailed analysis.
