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 reset after each use, making it an excellent choice for rental department.
