Cressi Giotto C2 Consoles

Product Overview

Giotto is the first mixed gas dive computer designed-and-built entirely by Cressi. Giotto's 3-button interface makes it effortless to program air, nitrox and gauge modes from the first time a diver picks the computer up. The high definition screen has 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 Giotto can also be fully reset after each use, making it an excellent choice for rental departments

The Cressi Giotto Computer has a new algorithm created through a collaboration between Cressi and Bruce Wienke based on the Haldane model, integrated with RGBM factors for safe decompression calculations in repetitive multi-day dives and with gas mixtures. The software handles two different hyper-oxygenated mixtures, which can be selected during the dive.

The Giotto computer by Cressi is a recreational advanced tool. It will provide all the necessary information depth, dive times, possible need of decompression, ascent rate and all the surface intervals between dives. Nitrogen absorption and release is continuously processed by its sophisticated software, considering the quantity of inert gas contained in the different mixtures that can be used. This information is shown on the device's large display via the PCD (Priority Compartment Digit Display) system that allows 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 12/24-hour format clock, calendar and a versatile dive memory (logbook 70 hr. or 60 dives). Computer is also altitude adjustable up to 12,139' (3,700m). The mathematical model of Giotto can make saturation and de-saturation calculations of dives carried out both with air and with nitrox in any moment of the dive. In this last case you can set all the parameters related to the mixture of your dive: from the maximum allowed PO2 value from between 17.4 to 23.2 psi (1.2 bars and 1.6 bars), to the mixture's oxygen percentage (FO2): between 21% and 99% of O2. Additionally, the device may be set by the user for either metric (meters- C°) or imperial system (feet- F°).

The Giotto Dive Computer has a backlight function for low light or night diving conditions, displays depth to 393' (120m), is altitude adjustable and has a user replaceable 3-Volt CR2430 battery. The computer comes with a gauge face guard, measures (D x H) 2.6" x 1" (65mm x 27mm) and weighs 4.77 oz. (135 g). The Computer also comes with a comprehensive owner's manual.

The Mini-Manometer Pressure Gauge luminescent dial reads from 0 to 5000 psi (0 to 350 bars). For at-a-glance monitoring of air. The instruments face is divided into three different colored zones: the area from 600 psi (50 bars) and below is highlighted-in-red with a slid-bar and red stripes. If gauge is used on deeper dives, the red-scale extends and fades to 1,300 psi (100 bars), this provides for added reserve air indication required at greater depths. From 600 psi to approximately 3,000 psi (bars to approximately 200 bars) is green and from 3,000 psi (200 bars) 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 instruments are 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 lightweight. The pressure gauge housing is durable chrome plated brass. The gauge boot has an attachment point for a clip or lanyard. The pressure gauge is equipped with a 7/16" threaded high-pressure hose.
