Garmin’s Descent Mk3i 51mm dive computer is now available in a new, two-toned black and silver titanium color design, the company announced this week.
The Descent Mk3i features multiple dive modes for single and multiple gas dives (including nitrox and trimix), gauge, apnea, apnea hunt and closed-circuit rebreather.
The Subwave Sonar Networking function allows the diver to exchange preset diver-to-diver messages up to 30 meters/98 feet as well as monitor tank pressures and depth for up to eight divers within a range of 10 meters/33 feet.
Additionally, the “Diveview Maps” allow you to see bathymetric depth contours and more than 4,000 dive sites to help you discover new places to dive and get oriented.
Above the water, it can show how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body — to help gauge when you are best prepared to dive.
Garmin also announced software updates for the second quarter of 2026 including:
- Setup Sharing: This feature seamlessley synchronizes two Garmin dive computers, ensuring each dive computer can function as a fully interchangeable backup to the other. Setup sharing allows you to sync settings and tissue load.
- Sidemount Tank Switch Guidance: When diving with sidemounted tanks, you’ll receive visual guidance on your compatible Descent dive computer when paired with a Descent T2 transceiver as a reminder to switch tanks at a preset pressure value. This allows you to keep tank buoyancy balanced and properly manage redundant gas supply throughout your dive.
