Best combo for the price.


These work great. Simple and effective. I have used this combo for several years for my personal setup and liked it so much that I am now including them on my rental and student kits.

The Cressi Leonardo Computer Console is an elegant expression of a simple and 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. Leonardo has a large edge to edge, high definition LCD screen that gives large numerical displays in a computer that is still compact and travel friendly. The Leonardo's easy to see battery life icon indicator and its distinct audible alarms deliver critical information as well as peace of mind during the dive.

The Leonardo features a new Cressi RGBM Algorithm, created in conjunction with the expertise of Bruce Wienke and based on the Haldane model, integrated with RGBM factors. This Algorithm allows for safe decompression calculations for multiple dives spread out over multiple days. 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, considering the quantity of inert gases 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 de-saturation 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 (17.4 and 23.2 psi), 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 (meters) or imperial (feet) system of measurements. The Leonardo can also be fully re-set after each use, making it an excellent choice for rental departments.

The Cressi Leonardo Dive Computer has an operational depth from 0 to 120 meters (0' to 393'), is powered by a user replaceable CR2430 3-volt battery and is equipped with a 60 dive (70 hour) logbook memory function. The clock function can be set in a 12/24-hour formats. The computer is also altitude adjustable up to 3,700 meters (12,139') and has a back-light feature for low light conditions. The computer comes with a comprehensive owner's manual.

The console is equipped with a submersible pressure gauge. The gauge has a luminescent dial that has readout from 0 to 350 bars. The instruments face is divided into three different Colored Zones: the area from 50 bars and below is highlighted in red with a solid bar and red stripes. If gauge is used on deeper dives, the red scale extends and fades to 100 bars. This provides for added reserve air indication required at greater depths. From 50 bars to approximately 200 bars are green and from 200 bars to end of scale are blue.

The front glass lens is made to act as a pressure relief valve. In the event of a sudden increase in pressure inside the instrument, the glass rises slightly, allowing the excess pressure to escape. The instrument is housed in a small, modern shaped console boot, made from Polycarbonate and Desmopan, (a thermoplastic polyurethane) two materials that guarantee protection from shocks, scratches and which, at the same time, is very light. Pressure gauge comes with a 7/16" high pressure hose. The entire 2-guage console is encapsulated in a durable impact resistant console boot with multiple attachment points for clips or lanyards.

Questions & Answers

Questions about this item:

n p  Can the SPG be removed from the console? Therefore, leaving just the gauge attached to the hp hose.
Frank L  The SPG is the pressure gauge, which is connected to the hose. So no.
Shopper  is the analog pressure gauge in psi or hbar?
JOSE S  I bought one in BAR but I believe LeisurePro has both. Just check it catalog.
Frank L  This is the metric version. We have it in imperial as well.
Shopper  Hello. Is this device air integrated?
Frank L  The computer is not air integrated. This is a console with a pressure gauge and a stand alone computer module. The computer will not display pressure information, hence, the analog pressure gauge.
