The Cressi Leonardo dive computer is Cressi's first in house designed fully functional dive computer. Compatible with both air and nitrox mixes it also comes in a range of colours.
The new Cressi RGBM algorithm, which was developed by Bruce Wienke, has been specially adapted by Cressi to offer safe decompression diving in a mutli day, repetitive dive format which makes the Leonardo particularly effectively for holiday/liveaboard diving scenarios. The algorithm accommodates nine tissue compartments with saturation hemi-phases between 2.5 and 480 minutes.
The single button ensures simple menu navigation whilst the large clear display makes it very easy to read. Audible alarms alert the user to important information and the backlight makes the details clearly even in low light conditions.
The user changable batteries help to keep maintenance costs down and prevent periods of down time whilst the battery is replaced at a service centre.
