Garmin Descent mk2, mk2i

 

Garmin has just launched the Descent MK2 and mk2i, which is their latest dive computer model.

Garmin Descent MK2i

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.

Here are the headline hardware changes

  1. Eh, no thank you! I’ll stay with my trusty Shearwater Teric.

    First, the price is outright ridiculous. I get it! It’s a land based Fenix and a dive computer in one not so tiny package, sure. But $1500 for that, with additional $400 for a proprietary transmitter? Yeah, right. Second, people hoped Garmin would use some already established A/I tech. Now, maybe their subwave sonar stuff is indeed revolutionary and the best thing since sliced anything, but I personally would prefer to wait until the next iteration. Let somebody else be a guinea pig-fish for A/I. Last but not least, it looks Mk2i will not be getting CIQ 4.0 (no current products will, according to Ray), which means somewhere in early 2021 feature updates for this insanely expensive piece of tech will stop. It’s Mk1 all over again.

    Which is a shame. Garmin could have made some serious inroads in this space had they be a bit less aggressive with pricing.

    1. Can’t argue with that (I’m feeling agreeable today)
      Whatever happened to that Suunto one a couple of years back. I was half down the road of getting one for a diving buddy of mine to test out but the venture petered out.
      The only thing i would say is that I’m pretty sure that Garmin will have tested this particular stuff properly, otherwise there is a very large lawsuit waiting to happen

      £1000: https://varuste.net/en/p100922/shearwater-teric-2020-limited-edition

      1. You can get Teric in the States for less than $1000. I got mine and a transmitter for about $1350 a few years back. While it lacks all Garmin smartwatch and GPS tracking goodies, it does have a huge bright AMOLED screen with easy to toggle brightness, very useful in deeper darker waters, fully configurable diving screens (Garmin used to have it pretty much locked up in Mk1 — you get what you get and you don’t get upset type of situation), and I personally dig Teric all black design better. And it’s Shearwater.

        I mean… Mk2i is a sweet-sweet piece of gear. But at close to $2000 for the whole package, it’s a hard sell. Especially given that it’s too bulky to be a daily type of wear thing like Fenix. Maybe on vacation. So, it doesn’t sound like Garmin is serious into moving into this market just yet. Kind of MARQ of diving.

  2. Like the blue buttons. If I had money to spare would buy it just for looks sake. As a nice bonus I would be able to get the badges I’m missing from Garmin Connect, since I don’t have a dive watch. 😛

  3. Relaxation reminders, although marketed, is not available on Descent Mk2i. Tried all available options – Garmin Connect phone app, Connect from browser and phone Stress widget. Wish it was available but so far it isn’t.
