"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
  • Thin, lightweight watch-style case with a bright 1.3in color display
  • Wireless multi-transmitter air integration standard on this tier
  • Higher Deep and Tech+ tiers available as upgrades if you need trimix or CCR later
Cons
  • No single authoritative USD price found, retail listings range roughly $400–$650 depending on color/retailer, with no official US price confirmed
  • Smaller support network in North America than major dive-computer brands
  • Nitrox-only, trimix requires stepping up to the Deep or Tech+ tier

The iDive Color Easy is the entry point into Ratio’s watch-style color computer line, a 1.3in IPS display, wireless air integration, and a choice of Bühlmann or VPM-B algorithms, with Deep and Tech+ tiers available above it for trimix and CCR.
