Suunto Cobra with SK7 compass

Suunto, known and recognized as the leader in dive computer technology and development introduces the air-integrated dive computer Cobra. With the Cobra, you have all the essential information for a successful dive at your fingertips.

The Cobra combines a multitude of advanced features found in the Vyper with the addition of air integration in a new design. Like the Suunto Vyper, the Cobra can be used for diving with standard air, nitrox mixes or it can be used as a depth gauge and timer all with profile memory. For easy use the Cobra has an interactive advisory display system which guides the user on what must and/or can be done next. The Cobra has been designed to allow tasks such as changing batteries and switching between metric and imperial units of measurement to be easily performed by the user.

The Suunto RGBM (Reduced Gradient Bubble Model) used in the Cobra is an advanced algorithm for tracking both dissolved and free gas in the blood and in the tissues of divers. The advantage of the Suunto RGBM is that it can address a number of diving circumstances outside the range of just dissolved gas models. For example, monitoring continuous multi-day diving, computing closely spaced repetitive diving and taking into account adverse dives deeper than the previous dive. In addition to displaying the decompression ceiling the Cobra also displays the decompression floor, the deepest point at which the divers decompression stop time will not increase. Suunto is the only manufacturer to display these two parameters determining the decompression stop range.

Cobra’s features include: complete decompression stop data, separate 3-step altitude and personal adjustments for more tailored settings, dive simulator and dive planner, customer selectable alarms for maximum depth and dive time, visual and audible alarms, automatic safety stop countdown, an electro-luminescent backlight which lights up automatically when important alarms are given, and a calendar clock.

The extensive memory functions include lifetime history memory and a 36 hour logbook with dive profile memory. The default 20 second sampling rate can be set to 10, 30 or 60 seconds. When set to the 60 second sampling rate, the diver can increase the logbook memory up to 100 hours.

The sampling rate is set by using the optional PC interface unit and Suunto Dive Manager software. The software upgrades are available free of charge at www.suunto.fi. During the dive, bookmarks can be entered into the computer’s logbook for further reference. The stored dive information, including profiles, can be read directly from the Cobra display or downloaded to a PC.

Air integration includes features such as temperature compensated tank pressure and estimated remaining air time with low cylinder pressure warning. The Cobra is 300 bar (5000 psi) compatible. As a nitrox computer the Cobra can be programmed for nitrox mixtures of 21% to 50% oxygen in 1% increments. The oxygen partial pressure can be adjusted from 1.2 to 1.6 bar in 0.1 unit increments. Includes Suunto quick disconnect and SK7 compass in module.
