The Garmin Descent Mk2i watch-sized dive computer with Carbon Grey DLC coated Titanium bezel and Black band features Air Integration. By adding wireless transmitter functionality Garmin has created the best recreational, technical and closed-circuit rebreather smartwatch dive computer on the market, hands down! Not only is it a dive computer with smartwatch functions but also a full multi-sport fitness watch with GPS, heart rate and pulse oxygen sensors that allow the Garmin Descent Mk2i to be a true all-in-one, everyday watch.

Scubalab Testers Choice Dive Computers 2020
The air-integrated Mk2i was so new when we received our test sample that its full manual wasn't yet available. Fortunately, it's so easy to set, navigate and operate that we didn't have an issue using it. In fact, no computer-scored higher for easy and intuitive operation—which is saying something because the Mk2i is packed with features including a heart rate monitor, GPS, mapping and a long list of fitness and adventure activities. "Lots to explore here," one tester noted. The 1.4-wide colour display is crisp, well-organised, and highly visible in all conditions, and test divers rated it excellent for readability underwater. Alternate dive screens offer extensive data, and you can scroll through them by button or with a double-tap of the screen. Graphics are clear and easy to understand, and critical data are accompanied with both audible and vibrating alerts. The Mk2i can view the tank pressure and battery status of up to four other divers, and can be paired with Garmin's diveable inReach Mini satellite communicator to receive text alerts and send an SOS on the surface. Despite the other goodies, the Mk2i is a dive computer first and foremost, and an excellent one at that. The Garmin Descent Mk2i is our Testers Choice for dive computers.

Monitor your gas and depth with the advanced, watch-style dive computer that comes with multisport training and smart features.

The original Descent Mk1 was a fantastic smart dive computer that brought true integration with your smartphone via Bluetooth technology but the Mk2i 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 is the option for wireless air integration. The Garmin Descent Mk2i can support up to 5 transmitters at a distance of up to 10 metres. 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.

Garmin Descent Dive Computers: Exploring Air Integration

As with the Mk2, the Garmin 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 Garmin Descent Mk2i doubles as a premium multi sport 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.
