Cressi Leonardo Wrist Computer

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.

Hello, these are stand alone units that will do everything except let you know how much air you have. The ones that connect the regulator are the air integrated versions. Thanks for your question, Bill
