The Garmin Descent G1 Dive Watch Computer is a fantastic smartwatch with multiple diving functions. Just like its sibling the Garmin Descent G1 SOLAR Dive Watch appeals to all active scuba divers and adventurers looking for exceptional value for money equipment with a multidisciplinary approach to fitness. From free diving to technical rebreather diving and from walking to professional fitness and health tracking - this is one amazingly versatile piece of equipment for underwater and surface sports.
The Garmin Descent G1 Watch for Diving
The Garmin Descent G1 dive computer is a powerful tool for any diver. It offers an abundance of surface and underwater modes every diver will find extremely useful. For underwater functions, the Garmin G1 Dive Smartwatch offers multiple and customisable dive modes such as single and multiple gas dives (air, nitrox and trimix), gauge, apnea, spearfishing and even closed-circuit rebreather and underwater 3-axis compass. On the surface, it empowers your scuba adventures by linking powerful satellite communication via an inReach2 Mini device or feeds data on ocean conditions via your smartphone. It is GPS enabled to help mark surface entry and exit points.
The Garmin Descent G1 for Sport and Fitness
The Garmin Descent G1 is also a powerful tool for any active sportsman and sportswomen. Super helpful sports functions include trail running, swimming, running, biking, hiking, rowing, skiing, golfing and more. It provides data on your fitness age recovery time, training status, respiration, sleeping patterns and many more. It offers an astonishing 30 built-in sports apps and advanced training features.
The Garmin Descent G1 Dive Watch's Design
The Garmin G1 smartwatch dive computer is designed for intensive use in and out of the water. The casing of the Garmin G1 is made out of the impact-resistant, fibre-reinforced technical polymer, and it is dive rated to 100m and built to match military spec MIL-STD-810. The screen is made of impact and scratch-resistant sapphire lens sheltering high contrast easy-to-read monochrome display. You can enjoy extended battery times with up to 25 hours in dive mode, 21 days in smartwatch mode and 26 hours in GPS mode.
