When Garmin released the Descent MK1, air integration was the one feature that it really missed. By adding wireless transmitter functionality, Garmin have created the best recreational, technical and closed-circuit rebreather smartwatch dive computer on the market, hands down! But diving isn't the only thing it is good for. Garmin has a lot of experience with developing watches for other sports and activities. The MK2i is built upon the blueprint of another popular fitness watch model, and that means full multi-sport fitness watch functions including GPS, heart rate and pulse oxygen sensors allow the Descent MK2i to be a true all-in-one, everyday watch.

The Descent Mk2i was awarded the Scubalab's Tester's Choice in their November 2020 edition, so we know that we aren't the only ones that think this dive computer is amazing.

The original Descent MK1 was a fantastic smart dive computer that brought true integration with your smartphone via Bluetooth technology, but the MK2 takes it so much further with a computer that is based on a popular, tried and tested, high-performance Garmin multi-sport watch. Obviously, it has been highly modified to suit our needs with a heavy-duty casing, 3-axis compass, new SubWave sonar-based wireless transmitter technology and ABC sensors. The beauty of basing it on an existing fitness / sport watch is that it packs loads of features for everyday use as well. No longer do you need a separate dive watch, dive computer and day-to-day watch.

Function wise, the only difference between the MK2 and the MK2i Titanium is the option for wireless air integration using the . The MK2i can support up to 5 transmitters at a distance of up to 10m. Unlike most transmitter, which use radio frequency (RF) to transmit the data, Garmin has developed a sonar-based technology. The biggest problem with RF waves is that they don't travel through water very well, whereas sonar works best in water which allows for the significant improvement in transmission range.

As with the MK2, the Descent Mk2i comes with ABC sensors, an underwater 3-axis compass as well as surface GPS capabilities to mark your entry and exit points. On land, the Descent Mk2i doubles as a premium multisport GPS smartwatch with multi-GNSS support, multiple sports apps, wrist-based heart rate monitoring, a Pulse Ox sensor, advanced training features, Garmin Pay™ payment service, music storage, smart notifications for calls, texts and calendar alerts and much more.
