"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
  • First Descent with an AMOLED touchscreen and sapphire lens
  • Deeper 200m depth rating than the Mk2 series
  • DiveView maps with over 4,000 preloaded dive sites
Cons
  • No wireless air integration, see the Mk3i for that
  • AMOLED display shortens raw dive-battery life versus the older MIP-based Mk2 (66h max vs 80h)
  • Available in 43mm only, no larger case option without stepping up to Mk3i

The Descent Mk3 moves Garmin’s dive line to a touchscreen AMOLED display and a deeper 200m rating, trading some of the MIP display’s battery efficiency for a sharper screen. It skips wireless air integration, which is reserved for the Mk3i.
