Product Overview

The Cressi Leonardo Wrist Computer, is a simple, beautifully designed dive computer offering an affordable price point without sacrificing function.  This is the perfect wrist mounted dive computer for those just entering the sport or those who want to keep it simple. 

With an intuitive, simple, single button operation, the Leonardo provides all vital information in a very readable format.  Air, Nitrox and Gauge modes are easily chosen with a push of a button.  Readability is excellent thanks to the edge-to-edge, high-definition screen, offering large numerical displays, while remaining compact and travel worthy.   The backlit display also shows date and time.  

The Leonardo includes user-friendly options such as the ability to set the conservancy level of profiles, utilizing the Modified Haldane and Wienke algorithm.  The FO2 is adjustable between 21% and 50% and the PO2 is adjustable between 1.2 bar and 1.6 bar.  CNS oxygen toxicity is monitored and graphically displayed.   An ascent rate alarm will warn the diver if the recommended ascent rate is exceeded and there is a user-selectable Deep Stop function.  The audible alarm has been heavily researched to maximize and clarify the sound underwater. 

The logbook feature stores up to 60 dives or 75 hours of information with a 20 second sampling rate.  An optional PC/Mac interface provides a simulator, dive profile function as well as dive information download. The interface uses IR to connect to the dice computer and a USB cable for the connection too either PC or Mac.  Battery life is displayed and the Leonardo uses a user changeable CR2430 battery which is useful when traveling.  

The Leonardo is designed and manufactured in Italy by Cressi, a brand pioneer in Scuba Diving, Snorkeling and Freediving equipment.  This computer can be fully reset after each use, making it an excellent choice for dive operation use.
