Does the Descent G1 Scuba Diving Computer track health metrics like Pulse Ox and Body Battery?

You should verify your wrist size fits the 1.79 x 1.79 inch housing to ensure the optical sensor maintains consistent contact for accurate data collection. Once confirmed, you can begin tracking your daily recovery and oxygen levels immediately.

Descent G1 tracks pulse oximetry and Body Battery via Garmin app

The Descent G1 supports pulse oximetry (Pulse Ox), which measures blood oxygen saturation, and Body Battery, a metric that estimates your body’s energy reserves throughout the day. These features are integrated into the device’s firmware alongside a sleep score and VO2 Max training feature. Because dive computers often have limited screens, these health trends are available via the Garmin Dive smartphone app for more detailed viewing. We selected the Descent G1 for this review because it offers a specific balance of dive-focused tools and fitness tracking among the watch-style dive computers we evaluated. For a scuba diver, tracking these metrics is vital because monitoring oxygen levels and physical recovery helps ensure you are physiologically prepared for the demands of a deep dive.

Comparing the Descent G1 to Other Dive Computers

The Descent G1 is a dedicated dive computer, which is a waterproof watch that displays depth and time limits for underwater safety. It features a monochrome display and a sapphire lens for durability. This model is ideal for divers who want a reliable, straightforward interface with essential safety features. However, if you require a high-resolution color screen or advanced multi-sport features beyond the 30 built-in apps, you might look at more complex smartwatch-style dive computers that offer larger displays and more complex mapping capabilities.

If you are planning an ultra-endurance event, find out if the Descent G1 powers a 20-hour triathlon.

If you need a durable dive computer that provides essential health tracking and reliable dive data, the Descent G1 is a strong choice. It is best suited for the diver who prioritizes a clear, functional interface and solid battery life over high-resolution color graphics.
