Garmin Descent Mk2S Watch Dive Computer

010-02403-0* 09/22

Have you always gazed fondly at the Garmin Descent Mk2 dive computer, maybe even tried one on but thought it was just a bit big to use as an everyday watch despite the huge list of surface/fitness functions that Garmin also packs into the smartwatch? Well, fret no more. Garmin has now released a smaller version, the Garmin Descent Mk2S, that is lighter, slimmer and has a smaller diameter. It was developed mostly for women that don't want such a chunky watch but also for anyone that just wanted a smaller model.

This is the smaller, watch-style dive computer that features multiple modes as well as multisport training and smart features.

From a function point of view, the Descent Mk2S is exactly the same as the standard Mk2. On the outside, the titanium bezel and back have been replaced with high strength composite components that all colour match the straps and also make the watch lighter.

The Garmin Descent Mk2S is still a full-on dive computer that supports Air, Nitrox, Trimix and CCR diving but, just like the standard Mk2, the Mk2S isn't air integrated so if that is an issue the Mk2i is the model for you.

The Garmin Descent Mk2S really does work seamlessly with your everyday life. For most, diving takes up a small percentage of your time, so having a dive computer that also connects to your smartphone, tracks your fitness efforts, sleep and so much more just makes complete sense.

The Garmin Descent Mk2S is the versatile watch-sized dive computer for you if you want a truly smart dive computer that's just a bit smaller! Think high-end dive computer, smartwatch and fitness watch all rolled into one device with a shed load of extra features on top of that. If you don't want to have to own multiple devices just to enjoy the activities you love then this is the smart choice.

ScubaLab Testers Choice 2021
With a 43 mm case and a weight of about 2 ounces, the Mk2S is the smallest, lightest computer we've ever seen. Pleasing to the eye, and comfortable to wear and operate, it took top score for ergonomics. The 1.2-inch high-resolution colour display is equally impressive, with excellent visibility and a sleek layout that presents data cleanly and clearly, with depth and NDL visible at all times. Testers were especially fond of the intuitive ascent/descent graphic. Alerts provide clear instruction and are accompanied by haptic feedback as well as audible tones. Simply double-tapping the screen will cycle through the alternate dive displays, which can be customised and provide divers with a stopwatch and digital compass. With a host of data, including a dive profile graphic and GPS coordinates, the computer's dive log scored excellently. The Mk2S also offers robust GPS, smartwatch and fitness capabilities, but remains incredibly easy to pick up and use, scoring excellent for intuitive operation. A favourite among testers, with outstanding performance, the Descent Mk2S is our Testers Choice.

Smaller, Versatile Watch Style Dive Computer with Surface GPS for Your Diving Adventures

Dive computer manufacturers have tried to bridge the gap between diving and everyday life with the watch style dive computer for many years but really all they have ever been is just a small dive computer. The Garmin Descent Mk1 was a big step forward with actually smartphone integration and a host of other features as well. Now Garmin has literally blown the competition away with the Mk2. It really is an evolutionary step forward for dive computers.

The Garmin Descent Mk2 does so much it is almost incomprehensible. As well as the normal recreational, technical and closed-circuit rebreather features you would expect in a high-end computer it also uses the built-in GPS to supplement your dive log information, when diving with the watch against your skin the heart rate and pulse Oxy sensors will also be recorded and used in your decompression calculations.

On land, it is a full-blown multi-sport watch with advanced training features, contact pay features, integration with music services, smart notifications and it has a phenomenal battery life. Install the Garmin smartphone app and desktop app and you'll benefit from the incredible support and update services that Garmin offers. Regular firmware updates continue to improve the function and features of the Descent Mk2 long after you make your purchase.
