Product Overview

The Garmin Descent MK1 dive computer watch is a fully featured, premium watch size computer with a bright color screen and not only supports scuba, it is multi-sport functional. 

 Famous for their GPS technology, Garmin includes GPS with the Descent MK1.  Through the full-color, onscreen mapping and location reference, divers can easily mark their dive’s entry and exit points, allowing for simple surface navigation and later reference.  This is accomplished through an advanced suite of built-in sensors including; 3-axis compass, gyroscope, barometric altimeter as well as GPS and GLONASS capabilities.  The easy to read compass display is available for both above and below the surface.  A simple “double-tap” will bring up the compass display.

The Garmin Descent MK1 supports all diving activities including recreational, technical and free diving, providing real-time data needed for confident diving.  Planning dives is accomplished directly on the Descent MK1. The computer is automatically activated when the diver enters the water, showing the current depth, dive time, water temperature, ascent/descent rate, no-deco time, decompression stop information, battery life and more on the unit’s crisp 1.2” color display.  The Descent MK1 utilizes the proven Bühlmann ZHL-16c algorithm making sure the diver stays within their dive limits.  

Audible tone and vibration alarms can be set to provide reminders at critical points of the dive. Up to 6 different gas mixes are supported, including nitrox and trimix (up to 100% oxygen), and it provides CCR (closed circuit rebreather) support. Configurable conservatism settings allow for the adjustment of personal safety limits. 

Beyond scuba, the Garmin Descent MK1 functions as a premium multisport watch suitable for daily wear.  This computer offers a complete set of sports/training, fitness and outdoor navigation tools, leveraged from Garmin’s popular fēnix line of high-end multisport watches. Owners can tap into an array of physiological metrics, running dynamics, fitness tracking features and more to monitor their workout stats, measure progress and help avoid injury.  

Special preloaded activity profiles are provided for swimming, running, biking, hiking, skiing, rowing, paddle boarding and more. Various timekeeping, lap counts and map tracking functions are easily accessible. Plus, for added motivation, you can even download advanced workouts and training plans to your device from Garmin Connect.

An impressive safety feature is the ability to pair the Garmin Descent MK1 dive computer with the inReach Mini® two-way satellite communicator (satellite subscription required).  Owners can receive notifications and weather on their wrists and even trigger an SOS from the surface.  When the inReach mini dive case is used, the system can be used to signal from the surface and is protected to a depth of 328ft (100m).  Information will not be transmitted while underwater.  

Crafted of premium grade materials, the Descent Mk1 dive computer is available in stainless steel bezel with treated silicone watch band or a deluxe titanium bezel version with brushed DLC titanium bracelet. Both models offer advanced GPS and GLONASS satellite reception, via an EXO™omnidirectional antenna in the bezel, for better reception in challenging environments (versus GPS alone). A bright, high-resolution, full-color Garmin Chroma Display™ with LED backlighting assures great readability in all lighting conditions, above or below the water. And for added scratch resistance, both models incorporate a high-strength domed sapphire lens.  The QuickFit® bands are highly adjustable and longer straps are included for use over thick wetsuits and drysuits.  

For all of its capability, the Descent MK1 has impressive battery life.  Expect 40 hours in dive mode, up to 19 days in watch mode, up to 10 days In smartwatch mode and up to 20 hours in GPS mode, all depending on settings.  Additional content such as watch faces, apps and data fields can be accessed through the Garmin Connect IQ™ store.  The Descent MK1 is wifi enabled.
