Cressi Leonardo

The Leonardo computer by Cressi is a multifunctional instrument for sport diving. It will supply any wanted information on depth, dive

times, decompression status, ascent rate and surface interval times between dives. Nitrogen absorption and release is continuously processed

by its sophisticated software, taking into account the quantity of inert in the different mixtures which can be used. Such information is displayed on the instrument’s large display, thanks to the PCD (Priority Compartment

Digit Display) System, allowing an easy and direct “dialogue” between the diver and the computer, ensuring a clear understanding of all

the data needed at any given time and a perfect readability in any situation. The computer is provided with clock and calendar, a versatile dive memory (logbook), as well as a dive simulator.

The mathematical model of Leonardo can make saturation and desaturation computations of dives carried out both with air and

with Nitrox, whose parameters can all be set:

from the maximum allowed PO2 value (between

1.2 bar and 1.6 bar), to the mixture’s

oxygen percentage (FO2) between 21% and

50% of O2. 

Additionally, the instrument may be set by the user for either metric (m-°C) or

feet system (ft-°F).
