The Cressi Leonardo Wrist Computer is an elegant expression of a simple and functional design, the Leonardo is a must-have for divers entering the sport and those who just want to dive. A single-button interface makes it effortless to program air, nitrox, and gauge modes. Leonardo has a large edge-to-edge, high-definition LCD screen that gives large numerical displays in a computer that is still compact and travel-friendly. The Leonardo's easy-to-see battery life icon indicator and its distinct audible alarms deliver critical information as well as peace of mind during the dive.
The Leonardo features a new Cressi RGBM Algorithm, created in conjunction with the expertise of Bruce Wienke and based on the Haldane model, integrated with RGBM factors. This Algorithm allows for safe decompression calculations for multiple dives spread out over multiple days. The Leonardo computer by Cressi is a multifunctional instrument for sport diving. It will supply any wanted information on depth, dive times, decompression status, ascent rate, and surface interval times between dives. Nitrogen absorption and release are continuously processed by its sophisticated software, considering the number of inert gases in the different mixtures which can be used. Such information is displayed on the instrument's large display, thanks to the PCD (Priority Compartment Digit Display) system, allowing an easy and direct dialogue between the diver and the computer, ensuring a clear understanding of all the data needed at any given time and a perfect readability in any situation. The computer is provided with a clock and calendar, a versatile dive memory (logbook), as well as a dive simulator. The mathematical model of Leonardo can make saturation and de-saturation computations of dives carried out both with air and with nitrox, whose parameters can all be set: from the maximum allowed PO2 value between 17.4 and 23.2 psi (1.2 bar and 1.6 bar), to the mixture's oxygen percentage (FO2) between 21% and 50% of O2. Additionally, the instrument may be set by the user for either imperial (feet) or metric (meters) system. The Leonardo can also be fully re-set after each use, making it an excellent choice for rental departments.
The Cressi Leonardo Dive Computer has an operational depth from 0' to 393' (0 to 120m), is powered by a user-replaceable CR2430 3-volt battery, and is equipped with a 60 dive (70 hours), logbook memory function. The clock function can be set in a 12/24-hour format. The computer is also altitude adjustable up to 12,139' (3,700m) and has a back-light feature for low light conditions. The computer comes with a comprehensive owner's manual.
