Garmin Descent Mk1 w/DLC Titanium Band

In Stock

The Garmin Descent Mk1 is a multi-gas nitrox and trimix decompression dive computer in a premium multi-activity GPS smartwatch that includes a titanium link wrist band and bezel with a diamond like carbon coating.

This version has a titanium bezel with blue accents and a titanium link wristband that requires the services of a jeweler to make a significant adjustment in length, plus a set of silicone wrist straps. The Mk1 is also available in a version with a stainless steel bezel with black accents and only the silicone wrist straps. Just to be clear, there is absolutely no other difference between the stainless and titanium versions than cosmetic styling and price, both versions have the same features and functionality.

  • Suitable for wear as your everyday timepiece
  • Bluetooth Smart, Wi-Fi and ANT+ supports notifications with your smartphone

  • Built-in sensors include depth, temperature, 3-axis compass, gyroscope and barometric altimeter
  • Bühlmann ZHL-16c algorithm with configurable Gradient Factors

For those sport and technical divers who like a wrist-watch form factor suitable for everyday wear, the Garmin Descent Mk1 builds on the features of their fēnix® 5X multi-activity GPS smartwatch to add SCUBA diving functionality. The Mk1 includes mixed-gas decompression dive computer functionality in a premium smartwatch with activity profiles, performance metrics and smart notifications. A high-resolution 64-color Garmin Chroma Display™ with LED back light assures readability in all dive conditions. Transflective technology that reflects and transmits light at the same time enables the display to also be readable under intense sunlight. The Mk1 supports dual satellite based navigation systems (on the surface only) with onscreen topographic mapping and pinpoint location reference — so you can easily mark your dive entry and exit points.

Once underwater, the Bühlmann ZHL-16C decompression algorithm with user configurable Gradient Factors allows individual control of your dive computer decompression calculations. Full color graphics plus tone and vibration alerts help keep you informed while you’re submerged. During a decompression dive, the Mk1 can provide time-to-surface based on "look ahead" at planned gas switches along with current ceiling and stop time. Multiple gas definition presets are supported with any combination of air, nitrox, trimix and oxygen. For technical dives, the Mk1 is user configurable to NOT "lockout" after a missed stop. Even underwater (if worn next to the skin), the Mk1 is able to measure and display your actual heartbeat rate.

On land, the Descent Mk1 also functions as a robust training and outdoor companion. It has profiles for running, cycling, swimming, as well as indoor workouts and recreational activities such as boating, golf, hiking, climbing, skiing and much more. Thanks to built-in Bluetooth, the Mk1 supports notifications from a paired smartphone. It's also Wi-Fi enabled to connect and automatically send activity uploads, including your dive logs, for review or sharing on Garmin Connect. What’s more, the Descent Mk1 design is suitable for wear as your everyday timepiece.

Tek Tip Warning Image WARNING
We consider the Mk1 high/medium/low safety factor settings, although typical of sport diving within no decompression limits, to be inappropriate for required stop technical diving, especially on trimix. Because the Mk1 does not have different gradient factor preset values for technical diving, we suggest divers rely upon the custom GF feature to select values appropriate for their stop required dives. Divers might consider starting out with a custom GF value of 30/70 until they build some experience with the Garmin Descent Mk1 on mixed-gas dives or dives with gas switches for accelerated decompression.
