Cressi Leonardo II Leo nardo is the first dive computer designed and built entirely by Cressi An elegant expression of simple, 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 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. The clearly visible battery life indicator and distinct audible alarms deliver critical information as well as peace-of-mind during the dive. The Leonardo can also be fully re-set after each use, making it an excellent choice for rental departments. -Air, Nitrox and Gauge modes -FO2 adjustable between 21% and 50% -PO2 adjustable between 1.2 bar and 1.6 bar -CNS oxygen toxicity graphic indicator-Single button interface (short push changes function, longer push selects functions)-Three levels of user-adjustable conservatism -User-selectable Deep Stop function -Modified Haldne and Wienke algorithm -Tissues: 9 with saturation hemi-phases between 2.5 and 480 minutes -Ascent rate alarm (10 m per minute) -Log book for 60 dives/75 hours of information with 20-second sampling rate-Battery life indicator -Distinct, easy-to-hear audible alarms -User changeable battery -Adjustable unit of measure: English or Metric -Backlit display -Built-in calendar and clock. -The instrument may be fully reset, in case of renting. -PC/Mac interface with dive profile (optional) Video: https://www. youtube. com/embed/bk86g3zrSYk "
