Garmin has released the latest models for their diving computer series. The Mk2 series has seen both hardware and software changes. Garmin has also altered the series - the more expensive version now comes with additional features besides the inclusion of the titanium band.

The Descent Mk2 | $2,149 AUD | All listed compatible accessories and included box content available on this page.

The Descent Mk2i | $2,499 AUD | All listed compatible accessories and included box content available on this page.

Just tell me what's changed?

The big new feature is that the Mk2i model can now pair with a Descent T1 Transmitter for integrated pressure monitoring on up to 5 tanks via Garmin's SubWave sonar data network.

Similar to the previous iteration, the core software is based on a fenix 6, but the body has gone through more rigorous testing along with additional diving only features added.

Hardware Design Change

The display screen size has increased from 30.4mm diameter to 35.56mm; the resolution has also increased from 240x240 (Mk1) to 280x280 (Mk2 and Mk2i). This increase has also caused the entire body to increase in size slightly up from 51x51 (Mk1) to 52x52mm (Mk2 and Mk2i).

The Mk2 series now also come with the Pulse Ox sensor to measure your blood oxygen saturation.

Battery

The Mk2 series has an improved battery life when compared to the previous iteration.

Software Features

Specifically looking at the new diving features, the Mk2 series now has support for the following:

  • Closed Circuit Rebreather (CCR)
  • PO2: up to 2.0 with customisable deco PO2 setting
  • Subwave Support (only on Mk2i)
  • Air Integration (via Subwave)
  • Gas Time Remaining and Consumption Rate (Mk2i only)

Because Mk2 series is based on the fenix 6 series while the Mk1 was based on the fenix 5 series, there are several general health and fitness features that are only available on the Mk2 series. I'll list some key highlights here but check the full specification breakdown below for a complete list.

Health and Monitoring

  • Mk2 series now include Pulse Ox, Stress Tracking and Body Battery Monitor.

General

  • Mk2 series now come with music storage and a larger memory capacity at 36GB
  • Additional batteries aver moves
  • Garmin Pay (Pay with your watch via NFC)

Safety Features

  • Live event sharing
  • Incident detection during certain activities

Gym, Fitness Training Features

  • Additional activity and training profiles
  • Yoga, Pilates and animated workouts
  • Training Load focus
  • Heat and Altitude Acclimation
  • PacePro Pacing Strategies

The Mk2 series also come with Golfing features (vector map for 42,000 golf courses, custom targets, scoring, etc.) and unique outdoor recreation profiles (hiking, trails, mapping for worldwide ski resorts and more).

Mk2 vs Mk2i – What's different between these models

The only real differences between these models are the included titanium band for the Mk2i and the compatibility with the Descent T1 transmitter along with the Subwave functionality.
