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 nre-set after each use, making it an excellent choice for rental purposes.
