Congratulations on your purchase of Giotto underwater computer
which offers the utmost safety
Always keep this manual with your Giotto.
MAIN FEA
CRESSI RGBM algorithm. 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.

Possibility of using two Nitrox hyper-oxygenated mixtures selected at any time of the dive.
Full setting of FO2 (oxygen percentage) and PO2 (partial oxygen pressure) parameters with the option to
set PO2 between 1.2 bar and 1.6 bar

Option to take a Nitrox dive after one with air (even while desaturating).
Option to set Deco (decompressive computations) or Gage (depth gauge and timer).
Deep Stop can be turned on or off.
Large display with “PCD System” for perfect understanding and readability of values.
Replaceable protective display cover
User-replaceable batteries.
Dive planning with manual safety curve scrolling.
User can switch unit of measurement from Metric (meters and °C) to Imperial (ft- °F) system.
Sound and visual alarms.

Backlit display
Built-in calendar and clock.
Log book (60 dives).
Dive history saved.
Option for full desaturation reset if needed, helpful when renting the device.
PC/Mac interface with general data and dive profile (optional).
