"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
  • Manages up to 3 nitrox mixes per dive
  • User-changeable, globally available standard battery
  • Bluetooth sync to Aqualung's companion app for logs and settings
Cons
  • No digital compass
  • No air integration on this model
  • Same segment LCD as the cheaper i200C, no color upgrade

The i300C sits just above the i200C in Aqualung’s recreational lineup, adding a third switchable nitrox gas and altitude adjustment up to 14,000 feet while keeping the same monochrome segment display and Pelagic Z+ algorithm.
