An elegant expression of simple, functional design, the Leonardo is a must-have for divers entering the sport and for those who "just want to dive". Leonardo is the first computer designed, developed and produced 100% in Italy by our owned subsidiary, Cressi Elettronica. It is an entirely modular, rugged computer with a wide UFDS display, which provides the proverbial ease of navigation and Cressi computer menus. It has complete Nitrox management, depth gauge mode, and a reset option. The algorithm incorporates RGBM and Deep Stop. Menus and navigation system identical to the rest of the Cressi diving computers, with ease of reading, access to information, and model parameter modification. A single-button interface makes it effortless to program Air, Nitrox, and Gauge modes the first time a diver picks the computer up, and an edge-to-edge, high-definition screen gives large numerical displays in a computer that is still compact and travel-friendly. Easy configuration, navigation through the various menus, and access to a large amount of information displayed intuitively. Features a "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 the button or when the alarm sounds. Extended battery life through a combination of systems: battery saver mode when the computer is not used with automatic power-on. The device is powered by a long-lasting CR2430 button battery which can be replaced by an authorized Cressi center by verifying perfect watertightness. The clearly visible battery life indicator and distinct audible alarms deliver critical information and peace of mind during the dive. Gauge calibrated in salt water for maximum precision during typical use. The dive settings can also be fully reset after each use, making it an excellent choice for rental departments.
