"Gas switches" is how many different mixes this computer can be programmed to switch between mid-dive, mostly relevant for technical/staged-decompression diving. It doesn't tell you which gas types (air, nitrox, trimix) are supported. See Gas types and the product description above for that.

Pros
  • Wireless tank pressure monitoring for up to 5 tanks via SubWave sonar with the Descent T1 transmitter
  • Titanium bezel and backplate, lighter than the Mk2's stainless steel
  • Same full multisport smartwatch feature set as the Mk2
Cons
  • Transmitter(s) sold separately and add real cost on top of an already premium watch
  • Priced well above dedicated dive computers with similar depth ratings
  • Superseded by the AMOLED Mk3i in Garmin's current lineup

The Mk2i is the Mk2 plus Garmin’s SubWave sonar-based wireless air integration, letting it track tank pressure on up to 5 cylinders through the separately sold Descent T1 transmitter. It’s since been joined by the Mk3i, which adds an AMOLED touchscreen.
