"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

Smaller, lighter case than the Mk2/Mk2i while keeping the full dive feature set
Lower price than the full-size Mk2
Same Bühlmann ZHL-16C GF algorithm and CCR support as the rest of the line

Cons

No wireless air integration
Smaller display than the Mk2/Mk2i
Still a premium price versus dedicated dive-only computers

The Mk2S shrinks the Descent Mk2’s case for smaller wrists without cutting dive functionality, making it Garmin’s answer to divers who found the full-size Mk2 too bulky.
