The main product line is the Garmin Descent series, which features advanced watch-style dive computers. These devices combine comprehensive dive functionality with full-featured multisport GPS smartwatch capabilities.

Air integrated models, such as the Descent Mk3i and Mk2i, pair wirelessly with the Descent T2 transceiver using Garmin's SubWave sonar technology. This allows divers to monitor tank pressure and, in the case of the Mk3i, enables diver-to-diver messaging and tracking of dive buddies.

Premium models like the Descent Mk3i and Mk2i offer advanced functions including Multi-GNSS surface tracking, support for multiple dive modes up to 11 gas mixes including Trimix and CCR, and a 200-meter dive rating. They also feature bright AMOLED displays and scratch-resistant sapphire lenses.

Yes, the Descent series is designed as an all-in-one device. It includes the full Garmin fitness-watch universe with features like wrist-based heart rate, advanced sleep monitoring, GPS for 100+ sports, music storage, and contactless payments via Garmin Pay.

The Diver Readiness feature provides the user with a score based on an analysis of personal data, including sleep score, recovery time, Body Battery level, and recent dive history. This helps divers assess their physical preparedness for their next dive.

Dive data is automatically recorded and can be logged and reviewed via the dedicated Garmin Dive app. This app allows divers to track their dives, review data like entry/exit points and tank pressure profiles, and share their experiences with a community of fellow divers.

The Garmin Descent G1 series is an excellent, rugged choice. It provides essential dive data, multiple dive modes, a long battery life, and comprehensive fitness tracking at a more accessible price point than the premium Mk series.
