The 3 button interface makes it effortless to program Air, Nitrox and Gauge modes from the first time a diver picks the computer up. The high-definition screen gives large numerical displays in a computer that is still compact and travel-friendly. The clearly visible battery life indicator and distinct audible alarms deliver critical information as well as peace-of-mind during the dive. The Giotto can also be fully re-set after each use, making it an excellent choice for rental departments. It has a new algorithm created through a collaboration between Cressi and Bruce Wienke based on the Haldane model, integrated with RGBM factors for safe decompression calculations in repetitive multi-day dives and with mixtures. The software handles two different hyper-oxygenated mixtures, which can be selected during the dive.
