Garmin Descent Mk1/Mk2/Mk2i Model Differences

For those sport and technical divers who like a wrist-watch form factor suitable for everyday wear, the Garmin Descent builds on the features of their premium multi-activity GPS smartwatches to add SCUBA diving functionality.

  • The Garmin Descent Mk1, introduced in 2017, builds on the features of their popular fēnix® 5X multi-activity smartwatch to add SCUBA diving functionality.
  • The Garmin Descent Mk2, introduced in 2020, offers diving functionality identical to the Mk1 but is based on their more advanced fēnix® 6X series that offers many additional non-diving related features such as a pulse oximeter, Garmin Music, and Garmin Pay.
  • Although Mk2 models are only 1 mm larger than the Mk1 in over all size, the most significant visual difference is the display of the Mk2 offers a 36% larger area (1.4 vs 1.2 inch diameter) with a slimmer bezel and higher resolution (280x280 vs 240x240 pixels).
  • Depending on the features enabled, the Mk2 also has a battery life about double that of the Mk1. The MK1 and Mk2 also use different USB data and charging clips.
  • The top-of-the-line Mk2i model adds support for their SubWave™ sonar data network which can share real time data — such as remaining dive time, gas consumption rate and more — while underwater during the dive between you and other Mk2i divers with {33 feet | 10 meters}.
  • The MK2i model also supports hoseless gas cylinder pressure integration, sometimes called air integration (AI), with up to five (5) separately purchased optional Descent T1 Tank Pod wireless pressure transmitters. No other Garmin Descent model (without the little 'i') supports AI.
  • The only other significant differences between the Garmin Descent models are their cosmetics, especially bezel materials and colors. Garmin sometimes offers bundles with specific accessory packages such as different wrist bands, but the core Descent features remain as described above.

On land, every Descent model also functions as a robust training and outdoor companion. They have profiles for running, cycling, swimming, as well as indoor workouts and recreational activities such as boating, golf, hiking, climbing, skiing and much more. They support dual satellite based navigation systems (on the surface only) with onscreen topographic mapping and pinpoint location reference. Thanks to built-in Bluetooth, they support notifications from a paired smartphone. All Descent models are able to connect via Wi-Fi and automatically send activity uploads, including your dive logs, for review or sharing on Garmin Connect.
