Cressi Goa Dive Computer

Cressi Goa Dive Computer

Perfectly suited to the needs of recreational scuba divers and freedivers.

The Cressi Goa Wrist Dive Computer features an easy-access menu and can be set for a 12/24-hour format with seconds and calendar functions. The computer has a precision stopwatch, second time setting, alarm clock, and backlit display for reading the computer's functions in low light conditions. Surface time, desaturation, and no-fly time calculator lets you know when the battery is low and can provide metric or imperial units of measure. The computer has a 50 dive per category memory logbook function.

The GOA is a Scuba diving/apnea watch-computer of extremely reduced dimensions. This small and compact computer has a diameter of only 1.89" (48mm) and a high contrast 1.38" (35mm) display with large, easy-to-read numbers. It is also an ideal watch for other underwater activities, thanks to the deactivation option of the "dive" functions that avoids unnecessary alarms ringing while you're snorkeling or swimming. The display is made of mineral glass, and the case is heavy-duty with steel buttons. The computer/watch is depth rated up to 394' (120m). The Goa computer comes with a rubber wristband featuring a stainless steel buckle and has a plastic/steel bezel and back cover.

The Cressi Goa uses Cressi's RGBM 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 Mathematical Model of Goa 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. The computer is also altitude adjustable up to 12,139' (3,700m), has a complete diving data processor, a graphic indicator of CNS toxicity level of oxygen, a safety stop indicator, multiple level safety factor configuration, and an algorithm for managing uncontrolled ascents.

The GOA is suitable for repeated, multiday decompression diving, and it is possible to alternate between nitrox and air diving even during desaturation. Visualization of time at dive phase, ability to add/remove deep stops, alarm in case of breach of ascent speed, decompression or PPO2, and ability to disable the ascent alarms if needed. Computer indicates time at dive phase, is completely resettable - useful for renting purposes, and provides planning scrolling of no-decompression limits.

Free Dive (Apnea) Program: This program provides a display of all diving parameters, such as depth, temperature, dive calculator, maximum dive depth, dive time, length of surface interval between each dive, and length of diving session. The apnea program also provides depth, dive time, surface interval alarms, recovery time alarm, and visualization of time at the dive phase.

Gauge Program (without decompression calculator): This function of the computer provides a depth/temperature indicator, average depth, dive time in minutes and seconds, has a re-settable depth stopwatch, and visualization of time at the dive phase.
Off Mode: Sensors disabled for snorkeling/swimming activities.

The computer comes with a screen guard, a quick reference guide, instructions for downloading the owner's manual, and has a user-replaceable CR2450 battery.
