The Garmin Descent Mk1 Dive Computer: Versatility For Your Aquatically Active Lifestyle

From ocean to office and everywhere in between

It may be hard to believe that there exists a dive computer that is perhaps suitable for any diver, but The Garmin Descent Mk1 is not your average dive computer. This wrist worn computer is made to flow stylishly into your daily life whether you’re at a business meeting or diving the USNS Vandenberg off the coast of Key West. Whether you want to go freediving or deep diving or use single gas or multiple gases or want to track your on-land workouts or monitor your sleep at night, or if you just want to have an ultra-sleek and stylish smartwatch on your wrist, this watch seems to have it all.

As a diver using the Descent Mk1, you’ll be able to access multiple functions and switch your modes easily while underwater when needed. This is a computer you can trust to help keep you safe on your ascent since it uses the conservative Buhlmann ZHL-16C algorithm. You won’t have to worry about struggling to see the valuable information portrayed on your computer’s sapphire crystal face since it uses vibrant full color graphics with LED backlighting, and the audible and vibrational alerts will sound off when it’s time for you to see what’s next for your dive. An additionally vital bit of info can be found on the watch when worn directly on the skin—your heart rate. Of course, not only will your heart rate read while you’re diving, this computer is designed to analyze your body’s response to your on-land workouts and training as well. And no matter where you are in the world, the Descent Mk1 can keep up with that too. By using dual satellite based navigation to pinpoint your need-to-know locations, it marks your entry and exit points when you dive down into the ocean or go cave diving inside a mountain, and it can even track your path, speed, and distance when cycling, running, and swimming your favorite triathlon trail.

Seems like a computer like that would use up loads of power pretty quickly, eh? Not exactly. If you’re using it simply as a watch it can last up to 19 days, as a smartwatch you have 10 days of use without having to recharge. As a dive computer, the Descent Mk1 can make it up to 40 hours! That’s an amazingly long battery life for a dive computer.

Another aspect of this computer you’ll love is that it’s not only supremely stylish, but it’s incredibly lightweight, and comfortable too, due to its titanium construction and strong yet flexible silicone band.

So keep your scuba lifestyle safe and stylish when you use the Garmin Descent Mk1 Dive Computer. With so much more versatility than your average dive computer, the Descent Mk1 will be the last dive watch, dive computer, fitness tracker, or timepiece you’ll ever need.
