The Garmin Descent Mk3i is a diving watch that combines advanced smart features with the functionality of a dive computer, featuring a 1.4-inch AMOLED display and 20 ATM water resistance.
The device boasts a 66-hour battery life in dive mode and up to 25 days in smartwatch mode, with an always-on display that can last around 10 days.
The watch includes SubWave sonar support, allowing divers to send preset messages underwater to others using compatible devices with a range of up to 30 meters.
The Garmin Descent Mk3i includes several advanced dive features, such as single and multigas setups, including Nitrox and Trimix, as well as freediving apnea gauge mode and closed-circuit rebreather diving.
Outside of the water, the Garmin Descent Mk3i functions like a full smartwatch, offering more than 80 sports apps, heart rate tracking, VO2 max, Pulse Ox, sleep tracking, and training suggestions.
