Cressi Giotto Computer

The device was designed and built entirely by an Italian company, and features a high-definition screen with a large digital display that includes battery life along with visual and audio alarms accessible through a three-button interface. Based on a new algorithm of the Haldane model, the device can be used in nitrox, air, or gauge modes. There are many other features such as deep stop option, a user-replaceable battery, 60 dive log backlit display, along with an optional PC/Mac interface. Audible alarms provide critical information as well as peace of mind during the dive. The Giotto can also be fully reset after each use, making it an excellent choice for rental departments. It has a new algorithm created through 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. Tissues: 9 saturation half-times ranging from 2.5 to 480 minutes. "Dive" program: full processing of dive data, including decompression if applicable, for every dive performed with air or nitrox. Full setting of FO2 parameters (oxygen percentage) and PO2 (partial pressure of oxygen) with the option to set PO2 between 1.2 bar and 1.6 bar, and FO2 from 21% to 99%. Option to take a nitrox dive after one with air (even while desaturating). Gage setting option (depth gauge and timer). Deep stop can be turned on or off. Replaceable protective display screen. User-replaceable batteries. Planning: decompression curve scrolling. User can switch units of measure from metric (meters and Celsius) to imperial (feet and Fahrenheit). Visual and auditory alarms. Graphic CNS oxygen toxicity indicator. Backlit display. Built-in calendar and clock. Log book (70 hours or 60 dives) complete with dive profile. Dive history saved. Option for full reset if needed, helpful when renting the device. PC/Mac interface with simulator and dive profile (optional).
