About Cressi Leonardo Computer Console with Compass

The Cressi Leonardo Computer Console with Compass 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, taking into account 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 17.4 and 23.2 psi (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 Imperial (feet) or Metric (meters) System. 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 393' (0 to 120 meters), 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 12,139' (3,700 meters) and has a Back Light Feature for Low Light Conditions. The Computer comes with a Comprehensive Owner's Manual and is covered by a 24 month limited warranty.

The Console is equipped with a Submersible Pressure Gauge. The Gauge has a Luminescent Dial that has Readout from 0 to 5,000 psi. The instruments Face is divided into three different Colored Zones: the area from 600 psi 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 1,300 psi. This provides for added reserve air indication required at greater depths. From 600 to approximately 3,000 psi is green and from 3,000 psi to end of scale is 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 compass also has a luminous dial for easy reading in low light conditions. The compass face is divided into 10 degree sections, has a side scan window for gun sight accuracy, lubber line, rotating bezel with double references and compass rose. The entire 3-Guage Console is encapsulated in a Durable Impact Resistant Console Boot with Multiple Attachment points for clips or Lanyards. The Pressure Gauge and compass are covered by a 12 month limited warranty.

    Comments about Cressi Leonardo Computer Console with Compass:

    This is a nice computer with plenty of functionality and features for the average rec. diver working with air or nitrox. My largest complaint is the terrible PC interface software and especially the PC interface itself if you have a Leonardo in a the compass console like this one.

    The interface is designed such that the computer has to sit as flush as possible, face down on the unit for it to 'see' the PC link signal from the computer. After I took a hack saw to mine and removed the thin plastic tab on one side of the interface, I am able to get the computer to mate with the interface, but just barely, and you have to hold it in your hand just so and be very still for the download to happen.

    Next, the computer software is abysmal and looks like something an undergrad created in a 1st semester labview class. I can find no way to bulk export my entire logbook and it appears one has to export each dive in the log as a single text file. It is a real shame that Cressi nailed the design of this computer but the whole PC interface and software seem like such an afterthought.

    Given the quality of the computer, I can still recommend it for some, but if you do a lot of diving and have an need for moving logs into other software, you may want to look at other computers.

    Questions about this item:

    Shopper  Why Did You Choose This?
    LYN H  We have found Cressi products to be of high quality at reasonable prices. My husband and I wanted a console computer that wasn't too complicated but with enough features that we could grow into as our diving experiences increase. We are happy with this selection.
    Shopper  Just to clarify - this is the Leonardo Console 3, yes?
    LYN H  When I looked on the Cressi website, the difference between the #2 and #3 is the number of dials. I purchased the 3 dial model with the compass and computer in front and SPG gauge on the back. A link in this Q&A section shows complete photos. FYI, while I haven't used mine in a dive yet, I like it so much already that I ordered another for my husband. The online class has been very helpful in getting us up to speed. Hope this info is helpful for you.
    Shopper  What replacement battery do you recommend and offer for this console?
    Marilyn S  The battery for the Cressi Leonardo is the 3.0 Volt CR-2430 Battery SKU: AQUBY2430!1
