"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
  • Bühlmann ZHL-16C algorithm with RGBM, a step up from Cressi's older pure-RGBM computers
  • Handles up to 3 nitrox mixes per dive
  • User-replaceable CR2430 battery
Cons
  • Bluetooth requires a separate BT Interface accessory, not built in
  • No digital compass
  • No wireless or hose air integration on this model

Cressi bills the Giotto as its first mixed-gas computer designed and built entirely in-house, running Bühlmann ZHL-16C with RGBM rather than the RGBM-only algorithm on the Leonardo and Goa. It targets divers who want 3-gas nitrox planning without stepping up to a technical-diving brand.
