After Leonardo, Giotto is the second project designed, developed and produced 100% in Italy by subsidiary Cressi Elettronica created 4 years ago. It is a completely modular, rugged and reliable computer. Cressi has complete control over the quality of the product, from the software programming to construction, manufacturing and post-sales service. Low relief profile with ergonomic design to properly fit the wrist and allow free movement of the hand. Stainless steel trim gives Giotto a technical, elegant and attractive appearance. Its wide-screen UFDS (User-Friendly Display System) provides the proverbial ease of navigation and Cressi software menus. It offers complete Nitrox management with the ability to use two different EAN mixes during the same dive. Air, Nitrox Gauge Modes. Reset option available through the menu, very useful when renting or for diving classes. This eliminates the residual nitrogen so that different users may make consecutive dives. The algorithm incorporates RGBM and Deep Stop (optional). Menus and navigation system identical to the rest of the Cressi diving computers, with ease of reading, access to information and model parameter modification. Easy configuration, navigation through the various menus and access to a large amount of information displayed intuitively. Four buttons for greater ease of navigation, accessing information and parameter modification. “User-Friendly Display System”. The information display, screen contrast, proportions and digit size have been carefully chosen for ease of use. All of the information presented is separated by light lines to facilitate reading even in stressful or emergency situations. Back-lit display activated by button or when alarm sounds. Extended battery life through a combination of systems: battery saver mode when the computer is not used with automatic power-on, low-consumption processor and CR2430 battery replaceable by the user without tools. The interface (optional) uses IR to connect to the diving computer and a USB cable for PC connection. Software compatible with all versions of Windows and with Mac. Gauge calibrated in salt water for maximum precision during typical use.
