"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
  • Compact 48mm watch-sized case, small enough for everyday wear between dives
  • Four modes (Air, Nitrox, Gauge, Free/Apnea) with adjustable PPO2 (1.2-1.6) across two switchable nitrox mixes
  • User-replaceable battery, no service center trip needed
Cons
  • Bluetooth/PC logging requires a separate Cressi Interface cable, not built in
  • No digital compass
  • Could not confirm current USD retail price

The Cartesio packs Cressi’s RGBM algorithm and four operating modes (Air, Nitrox, Gauge, and Free/Apnea) into a 48mm watch-sized case, aimed at divers who want one computer that covers scuba, gauge diving, and freediving without swapping gear. It supports two switchable nitrox mixes per dive rather than the single blend on Cressi’s cheaper puck computers, positioning it a step above the Leonardo line.
