"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
  • Monitors up to 3 wireless transmitters for multi-gas or multi-diver setups
  • Bluetooth sync, unlike many budget Mares computers of its era
  • User-replaceable CR2450 battery good for 100-150 dives
Cons
  • No digital compass
  • Small 1.25in display next to larger console or watch-style rivals
  • Older RGBM algorithm rather than Bühlmann ZH-L16C
Diver community sentiment
Mixed opinions

On Scubaboard, divers who compared the Smart Air to Mares' cheaper Puck Pro+ generally felt the extra cost was worth it for the customizable display and air-integration capability, though one experienced user found the second button didn't add much practical value and noted the screen felt smaller than the Puck Pro+. The most recurring complaint across multiple threads is post-dive log download: several separate users independently reported that Mares' own Dive Organizer software failed to recognize the Smart Air, with fixes requiring either updating to the latest Mares software or installing a third-party USB driver. No divers reported problems with underwater performance or air-integration accuracy.

Summarized from public forum discussion (Scubaboard, Reddit, and similar), not a survey we ran ourselves. See the linked threads for the original conversations.

The Smart Air adds wireless air integration to Mares’s entry-level Smart computer, keeping the same compact segmented display and RGBM algorithm while adding support for up to three tank pressure transmitters.
