Garmin Expands Descent Mk3i Lineup with New Black and Silver Titanium Colorway

Garmin has introduced a new color option for its Descent Mk3i dive computer — a two-toned black and silver titanium finish for the 51mm model. The new variant retails at $1,599.99 and will be available to order.

The Mk3i supports multiple dive modes including single and multi-gas configurations for nitrox and trimix, as well as dedicated modes for gauge, apnea, apnea hunt, and closed-circuit rebreather diving. For freedivers, the apnea modes provide depth, time, and surface interval tracking.

One of the Mk3i's standout features is SubWave sonar networking, which allows divers to exchange preset messages up to 30 meters apart and monitor tank pressures and depth for up to eight divers within a 10-meter range.

The titanium construction keeps the watch lightweight while offering scratch resistance and durability suited to both diving and everyday wear. Technical specifications remain identical to existing Mk3i models.

The new colorway expands the Descent Mk3i lineup, which already includes carbon gray titanium and stainless steel options. It is available through authorized Garmin retailers worldwide.
