"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
  • Adds normoxic trimix on top of the Easy tier's air/nitrox support
  • Up to 3 wireless transmitters for gas monitoring
  • Same thin, lightweight watch-style case as the Easy tier
Cons
  • No single authoritative USD price found, retail listings range roughly $495–$600 depending on color/retailer, with no official US price confirmed
  • No CCR support, that requires the Tech+ tier
  • Smaller support network in North America than major dive-computer brands

The iDive Color Deep steps up from the Color Easy with normoxic trimix support, aimed at divers moving into early technical diving without giving up the line’s thin watch-style case and color display.
