About Garmin Descent G1 The Garmin Descent G1 is a versatile dive computer and GPS smartwatch that combines advanced diving functionality with comprehensive fitness tracking features. Designed for both underwater and land-based activities, this rugged device offers a high-contrast monochrome display, multiple dive modes, and a battery life of up to 25 hours in dive mode or 3 weeks in smartwatch mode. Adapt to Any Dive Style with Six Specialized Modes The Garmin Descent G1 offers six dive modes to match different diving styles and preferences. These modes provide tailored features for various underwater activities: Single-Gas & Multi-Gas Modes: Support up to 12 gas mixes with oxygen content ranging from 5% to 100%. CCR (Closed-Circuit Rebreather) Mode: Allows for two partial pressure of oxygen (PO2) setpoints and supports both closed-circuit and open-circuit gases. Gauge Mode: Provides essential bottom timer features. Apnea & Apnea Hunt Modes: Designed for freediving, with Apnea Hunt mode specifically optimized for spearfishing. The device enables divers to set up multiple breathing gases, including oxygen and helium percentages, ensuring accurate decompression calculations. For precise dive predictions, only gases that will be used should be enabled. Stay Powered Longer with Extended Battery Life The Garmin Descent G1 offers impressive battery life across different activity modes, allowing for extended use in various conditions: Dive Mode: Up to 25 hours of use. Smartwatch Mode: Lasts up to 21 days, or up to 124 days with solar charging (G1 Solar model). GPS Mode: Provides 26 hours of battery life, extending to 39 hours with solar charging. Factors like GPS usage, backlight settings, and enabled sensors may impact battery life. Dive activities consume more power, typically draining 5-10% per 1-1.5 hour dive. To maximize battery efficiency, divers can adjust power modes, disable unnecessary features, and take advantage of solar charging for extended performance.
