The Suunto Vyper Air is a nitrox wrist mounted dive computer. For those of you who are beginner divers, a dive computer can be a highly useful tool you might use whilst learning about diving.
The easy to read interface makes it the best choice for beginner divers, but also has advanced features which suit someone who is keen to learn. It features 3 dive modes, Air, Nitrox, and Gauge mode, with the option to switch between two gas mixes. Each mode does as follows:
- Air Mode – This mode is used when diving with standard air only
- Nitrox Mode – This mode is used when diving with oxygen enriched dive mixtures and has the ability to switch between two gases on the dive. Nitrox mixes can also be programmed in one percent increment between 21% and 100% oxygen.
- Gauge Mode – In this mode the dive computer can be used as a bottom timer or for free diving. It will not make any decompression calculations therefore will not show any warnings or alarms.
It also can show you your tank pressure and remaining air time on the same display as your other important dive information.
There is also a 3D compass on the device with 45 degrees tilt technology as well as an amazing dive simulator which allows you to test potential dives without setting a foot in the water.
The Suunto Vyper Air has a very intuitive menu base user interface with the ability to back step, which makes navigating easy. It has 4 operation buttons; MODE, SELECT, and the UP/DOWN buttons.
There are also two bar graphs which shows your current tank pressure and ascent rate. Overall, the display is amazingly clear, and with the ability to configure the back-lighting to illuminate for 5,10, 20, 30, and 60 seconds, you can use this dive computer in any lighting condition.
The Suunto Vyper Air uses Suunto’s RGBM (Reduced Gradient Bubble Model) algorithm developed by Dr. Bruce R. Wienke, based on both diving and laboratory tests as well as data from DAN. The Algorithm takes into account both dissolved and free gases in your tissues and blood, the result is a greater margin of safety for divers.
The Deep Stop feature incorporated in the algorithm allows the Vyper Air to calculate continuous decompression for excellent ascent time. If you are planning on diving deep, the deep stop option adds further protection with a series of deep stops between your maximum depth and ceiling.
In the Suunto Vyper Air there is also the ability to set the RGBM Algorithm to become more Liberal. If you are an experienced diver you can set the RGBM from 100% to 50%, however you should only do this if you’re willing to take the added risk this might cause to your health and well-being while diving.
Also induced is a dive simulator which allows you to run through actual dive profiles, in either air or nitrox, without being in the water.
The optional wireless air integration lets you control your tank pressure right on your wrist along with your current air time remaining and other crucial dive information.
The device also has both audio and visual alarms to alert you to all dangerous situations.
The Suunto Vyper Air dive computer uses a R2450 user changeable battery that should last about 100 dives or 2 years.
Changing the battery is straight forward with detailed instructions in the manual. However, changing the battery is a delicate process and should be done carefully.
The dive log on the device is a useful feature when you want to analyse your past dives, and the Suunto Vyper Air actually has a very sophisticated dive log. It also can save about 42 hours of dive time. One of the best features is that you can bookmark a certain point of your dive. When you download the dive log to your PC the bookmarks will log the current time, depth, water temperature, tank pressure, and your compass heading at that particular point in the dive.
Suunto Vyper Air Verdict
All in all, the Suunto Vyper Air make a great dive computer for any diver, whether or not you are a beginner or experienced. It’s easy to read display and intuitive user interface makes operation and find out your most critical diving information a breeze.
