Garmin Descent mk2, mk2i
Garmin has just launched the Descent MK2 and mk2i, which is their latest dive computer model.
At heart, it’s a Fenix 6 that’s REALLY not designed to leak even when diving at 100m. The headline feature is compatibility with the new Descent T1 tank pressure transmitter which uses a new sonar-based communications method called Garmin SubWave.
The price tag has shot up from $1000 for the MK1 to a mouth-watering $1500 for the MK2i. You DO get more for your money.
What’s New in the Garmin Descent MK2i?
There are improvements and additions across the board, some of them minor.
The case format is slightly increased but more notably we see an increased real screen size and we can expect that to hit other new Garmin models like the 655, note that the pixel density is the same. Also of note is improved battery life but recent Garmins seem to be eating through the battery faster than they should, so be mindful of that.
There are two new models: MK2 and MK2i with the ‘i’ representing the new Air Integration compatibility with the air integrated tank pressure monitoring using Subwave technology.

- Connectivity is unchanged except for the interesting addition of SUBWAVE compatibility.
- We also see Garmin PAY and the ability to store about 2000 songs
- Live event sharing, incident detection and assistance features are available – not sure if they will work in dive activities.
