Cressi Goa Dive Computer
After the successful Leonardo, Giotto, Newton and Drake, GOA is the fifth project designed, developed and 100% produced in Italy by its subsidiary Cressi Elettronica. It is a clock-format computer of completely modular construction, extremely robust and reliable. Cressi has all the quality control of this product because it is entirely developed and manufactured in Cressi Elettronica, both in terms of software programming and in its construction and manufacture, quality control and after-sales service.
It is an elegant and polyvalent proposal, under its aspect of modern and attractive watch hides a complete dive computer and apnea that stands out for its versatility.Suitable for the advanced diver or for technical diving and for apnea or snorkelling,but surprisingly simple for the average diver by providing information clearly and simply with just two buttons.
- Anti-impact technopolymer case. This composition allows a great lightness, resistance to the blows and to the aesthetic aging. The computer case is extremely flat, with a very hydrodynamic cornerless section and its dimensions are relatively contained, with a vision of the model digits.
- Extra-flat profile (maximum height 14 mm) with a completely rounded design, very hydrodynamic and avoids possible snagging. Even the anchorage of the strap follows the profile of the box.
- Two highly integrated low-profile pushbuttons with the minimised backlash to ensure that the O-rings are watertight when working perfectly perpendicularly and to prevent the entry of particles or small grains of sand that could block them.
- Case diameter only 48 mm
- Large screen UFDS (User-Friendly Display System) 38 mm in diameter vs 48 mm total box. The distribution of the information, screen contrast, proportions and size of the digits have been studied to facilitate the reading. All data are segmented with slight separation lines that facilitate reading even in a stressful or emergency situation.
- New high-performance, low-power processor. Allows much faster data processing, more power backlighting and sound alarms and doubles the battery life compared to previous models. CPU ARM Cortex M3 32 bit | Frequency14 MHz | Flash Memory 256 Kb | 32 Kb RAM
- High intensity backlit display by push-button or in case of alarm (5 seconds per push)
- High-strength mineral crystal display
- Guaranteed resistance up to 120 m depth
- Optional Bluetooth interface
- Thermoplastic rubber strap with stainless steel buckle
- New menu navigation system and parameter input for maximum usability and it is intuitive. The ease of configuration, navigation through the different menus and access to a large amount of information is always very intuitive.
- Clock 12/24 hours with calendar and seconds
- Precision chronometer
- Alarm Clock
- High intensity backlight function
- Indication of no-fly time and desaturation time
- Low battery indicator
- Metric or imperial units
- User-replaceable battery
- OFF MODE for use in snorkelling/swimming
- LOG BOOK with the historical memory of 50 dives per mode or 40 hours.
- Air, Nitrox (EAN), Gauge and Free modes.
- Extremely long battery life through a combination of systems: economy mode when not using the computer with automatic start and a new low-power processor. CR2450 Battery
- Interface with connection to the dive computer simply supporting the computer and connection to the PC with a USB cable. Software is compatible with all Windows and Mac versions.
- Depth gauge calibrated in saltwater for maximum accuracy in the most common use
- Five colours available: Black-Grey, Black-White, Black-blue, White-Pink, White-Black
- Possibility of deactivating DIVE functions to avoid unnecessary alarms during snorkeling or swimming.
- Polyvalent Air/Nitrox
- Possibility of using two different mixtures in the same immersion, 1st mix from 21% to 50%, 2nd mix from 21% to 99% O² with 1% increments
- Modified RGBM Wienke 9 tissue algorithm

- Optional safety stop (“Stop”) in case of dives in the safety curve
- Approximate autonomy of 4 years (50 dives per year)
- Temperature, time, instant PO2, maximum depth allowed and mix used visible underwater at the press of a button
- High power backlit display (one-touch, 5 seconds)
- Reset option via a menu. Eliminates residual nitrogen memory for use in dive centres for rental or teaching.
- Time display during the dive
- Possibility of silencing ascent rate alarms.
- Studied to provide the necessary basic parameters for diving with mixtures with decompression tables calculated by specific programs.
