Designed and built by an Italian manufacturer entirely, the instrument has a high definition screen with a large numerical display which includes a battery life along with visual and audio alarms that can be accessed by a three-button interface. Based on a new algorithm of the Haldane model, the instrument can be used in nitrox, air or in gauge modes. There are many other features such as deep stop option, a user replacable battery, 60 dive log book backlit display along with an optional PC/Mac interface.
Audible alarms deliver critical information as well as peace-of-mind during the dive. The Giotto can also be fully re-set after each use, making it an excellent choice for rental departments. It 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 mixtures. The software handles two different hyper-oxygenated mixtures, which can be selected during the dive.
Tissues: 9 saturation half-times ranging from 2.5 to 480 minutes.
”Dive” Program: Full processing of dive data, including decompression if applicable, for every dive performed with Air or Nitrox.
Full setting of FO2 parameters (oxygen percentage) and PO2 (oxygen partial pressure) with the option to set PO2 between 1.2 bar and 1.6 bar, and FO2 from 21% and 99%.
Option to take a Nitrox dive after one with air (even while desaturating).
Gage setting option (depth gauge and timer).
Deep stop can be turned on or off.
Replaceable protective display screen.
Planning: decompression curve scrolling.
User can switch units of measure from Metric (meters and C°) to Imperial (feet and F°).
Visual and auditory alarms.
Graphic CNS oxygen toxicity indicator.
Built-in calendar and clock.
Log book (70 hr or 60 dives) complete with dive profile.
Dive history saved.
Option for full reset if needed, helpful when renting the device.
PC/Mac interface with simulator and dive profile (optional)
The Cressi Giotto wrist computer is so easy to operate and very comfortable to wear, plus the layout of the screen makes seeing the information much easier read than my previous computers.
