Suunto Stinger ACW - Rubber strap Dive Computer
The Suunto Stinger has a pressure rating of 20 ATM (200 m/660 ft) and is marketed as the only Advanced Computer Watch in the world of separate Air, Nitrox and Free/Gauge modes. In a nutshell, the Stinger is a full decompression dive computer that’ s wonderfully compact yet manages to incorporate a variety of advance features such as adjustable profile memory sampling rate, easily accessible bookmarks, metric/imperial unit selection based on your preference, safety stop countdown and underwater stopwatch. The computer is multi level and has the capacity to monitor and report any information vital to a safe dive. It offers two patented customizable displays that can be alternated underwater with the push of a button. The Stinger can be adjusted for diving in varied altitudes of up to 3000 metres. It has a one second precision timer with user changeable 4, 10, 20, 30 or 60 second profile memory sampling rates. It automatically changes to Gauge mode after five minutes of continuous diving in the Free mode. The casing of the Suunto Stinger ACW is stainless steel. The display is scratch-resistant mineral glass that will last for many uses. The Stinger is virtually leak proof because of its monocase design without separate rear cover.

The decompression calculations are made with the Suunto Reduced Gradient Bubble Model, RGBM. DIVE COMPUTER FUNCTIONS As a highly sophisticated multi-level dive computer in every sense the Suunto Stinger monitors and reports vital information such as your dive time, current depth, maximum depth, no-decompression time and ascent time. As in the Vyper and Cobra, Stinger implements the ceiling and floor feature. The Floor is the deepest depth at which the ascent time will not increase. The Ceiling is the shallowest depth to which you should ascend. These depths will provide the range at which the diver most efficiently will utilize the decompression stop. The Suunto Stinger A.C.W. offers two patented customizable displays giving you the freedom to choose before each dive what your Stinger displays during the dive. When underwater the chosen displays can be alternated with other displays for 5 seconds by push of a button.

The Stinger can be adjusted for diving at altitudes up to 3000 m (10000 ft) and a personal level of conservatism can be added if desired. The Suunto Stinger enables you to set dive time and maximum depth alarms before your dive. The clear blue electroluminescent backlight activates automatically when dive alarms are given, making the dive parameters clearly visible and legible. The system is highly energy-efficient with only minimal power drain. Stinger’s built-in dive planning function helps you to plan your next dive by showing you the no-decompression time data for different depths. As a nitrox computer the Stinger can be programmed for nitrox mixtures of 21% to 50% oxygen in 1% increments and adjusted for oxygen partial pressure from 1.2 bar to 1.6 bar in 0.1 unit increments. Stinger gives both visual and audible alarms when the limit for oxygen partial presure, CNS or OTU values are exceeded. For freediving Stinger introduces a one second precision timer with user changeable 2, 4, 10, 20, 30 or 60 second profile memory sampling rates. After 5 minutes of continuous diving in the Free mode the Stinger changes automatically to Gauge mode.

In both Free and Gauge mode there is the option to use a run-time timer. This makes Stinger ideal also for technical and military diving. In Air and Nitrox modes, you get 36 diving hours profile memory with the default 20 second sampling rate setting. This sampling rate can be changed to 10, 30 or 60 seconds using the PC-interface. Profile memory, as well as long-term history data, can be viewed from the Stinger display. For a more detailed dive logbook you can download your dives to a PC with the Suunto Dive Manager (SDM) software and interface. WATCH FUNCTIONS As a watch the Suunto Stinger incorporates complete calendar clock functions, dual time, daily alarm and a stopwatch with elapsed time and split time measurement. If you choose to disable all the dive modes, the Stinger can even be used in water as a traditional dive watch, complete with stopwatch functions. DESIGN The casing of the instrument is all stainless steel and the display is scratch-resistant mineral glass. The Stinger’s triple o-ring pushbuttons and monocase design without separate rear cover make it virtually leak proof. The pressure rating is 20 ATM (200 m/660 ft).

The Stinger cost about $450.00
