Giotto is the first Mixed Gas Dive Computer Designed-and-Built Entirely by Cressi Giotto"s 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 has 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 The Cressi Giotto Computer 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 Gas Mixtures The Software handles Two-Different Hyper-Oxygenated Mixtures, which can be selected during the dive The computer Giotto by Cressi is a Recreational Advanced Tool It will provide all the necessary information Depth, Dive Times, possible need of Decompression, Ascent Rate and all the Surface Intervals between dives Nitrogen Absorption-and-Release is continuously processed by its Sophisticated Software, taking into account the Quantity of Inert Gas contained in the different Mixtures that can be used This information is shown on the Device"s Large Display via the PCD (Priority Compartment Digit Display) System that allows an Easy-and-Direct "Di
