• Amazon: Suunto Vyper Dive Computer
• Pros: Option for air integration. Dual nitrox switching. On-board dive simulator. Many user definable features.
• Cons: No battery hot swap.
• Recommended Uses: The Suunto Vyper dive computer is suitable for any diver; beginner or experienced. You can start using it for simple air dives and as your skills and knowledge increase, you have the ability to set it up for wireless air integration and nitrox, so this computer will grow with you as your needs change.
The Suunto Vyper incorporates 3 dive modes; Air, Nitrox and Gauge with dual nitrox switching capabilities. It also includes optional wireless air integration which gives you the added benefit of receiving cylinder pressure information and air time remaining on the same unit as your other critical data – no more chasing hoses and gauges around underwater! If other divers are using Suunto Vyper wireless transmitters, you need to manually reset the internal code so each diver is using a unique one, ensuring that you are reading the pressure information from your own cylinder.
Useability and Features
The Suunto Vyper’s completely redesigned user interface means that the display is amazingly clear and easy to read, and with user programmable backlighting you can use this computer under any lighting conditions. The electronic 3D compass makes underwater navigation a breeze and can also be used on the surface if required. You can set the compass readings to time out after 1, 3 or 5 minutes after which time it returns to the mode you activated it from ; either Time or Dive. The 4 button operation is a little more complex than some comparable dive computers, however the user manual is perfectly structured and extremely easy to follow with detailed graphics of all the computers functions and how to access them.
Suunto dive computers are renowned for the number of settings the user can change, and this means you can truly personalise the Suunto Vyper dive computer for your individual requirements. You can change Depth alarms and Dive Time alarms and switch between the Safety Stop and Deep Stop options. Experienced divers can set the RGBM from 100% to 50% if they are prepared to accept the added risk that applying a lower RGBM effect poses to their health and well being while diving. There is the option of setting a secondary Tank Pressure alarm between 10 and 200 bar – this is in addition to the Primary Pressure alarm which is factory set and non changeable at 50 bar.
Choose from 3 Altitude Adjustment settings when you’re diving at altitude and 3 Personal Adjustment settings for added safety and further conservatism during the dive. Like other Suunto dive computers, the Vyper uses a continuous decompression feature which will inform you of how long to stay at the shallowest depth allowable for this dive (Ceiling), how long it will take you to ascend to the Ceiling, the time needed at the Mandatory Safety Stop depth and the time needed to reach the surface after all other conditions have been met.
There are 2 bar graphs which represent your Ascent Time and Tank Pressure – great for those divers who prefer graphical representations of data rather than just numbers. The Vyper has user replaceable batteries but doesn’t include a hot swap option, so oxygen absorption and nitrogen loading calculations will be lost on changing the battery.
A handy feature for when you’re on the surface and want to analyze your dives is the ability to bookmark certain points in your dive. Set the bookmark and it will be shown as an annotation when you download your dive log to your pc. Bookmarks log water temp, time ,depth, tank pressure and compass heading at a particular point during your dive. Also included in this model is and on-board dive simulator which allows you to run through actual dive profiles for either your AIR or Nitrox dives.
