"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.

  • Single-button interface across Air, Nitrox, Gauge and Free modes
  • User-replaceable CR2430 battery

  • No digital compass

Diver community sentiment
Mixed opinions

Real Scubaboard discussion of the Donatello skews toward brand skepticism and support complaints rather than the enthusiasm found on marketing-style review sites. One thread saw a dive instructor bluntly advise a prospective buyer to skip Cressi computers altogether, suggesting Scubapro, Aqualung, or a Shearwater Peregrine instead. A longtime owner (100+ logged dives) documented frustration that Cressi discontinued support for its UCI desktop software, breaking JSON export/import compatibility with tools like Subsurface, though downloading recent dives directly to Subsurface still worked. No thread was found containing strong unprompted praise for the Donatello's diving performance itself.

Summarized from public forum discussion (Scubaboard, Reddit, and similar), not a survey we ran ourselves. See the linked threads for the original conversations.

The Donatello is one of Cressi’s newer wrist computers, built around a bigger, higher-definition display than the classic Leonardo/Giotto line while keeping the same single-button simplicity. It handles hyperoxic nitrox mixes up to 50% O2, but pairing it to a phone still means buying Cressi’s separate Bluetooth interface cable.
