The Suunto Vyper Dive Computer is an older model than Suunto’s D6 and D9 dive computer models and so as you might expect does not offer the same number of functions packed into those two models. However, that does not mean to say that the Suunto Vyper should not be considered if you are looking for a dive computer offering performance, ease of use, a bunch of useful functions and of course good value.

Features of the Suunto Vyper

The Suunto Vyper has numerous functions to make the most choosey of divers (both advanced/professional divers and those relatively new to diving) go weak at the knees. Suunto has built into the Vyper full decompression functions, standard air or Nitrox mix modes, a depth gauge function and a timer including a profile memory.

Like Suunto’s D6 and D9 models, the Suunto Vyper also records and saves information about your dives so that you can look at it at a later date. This is achieved via a PC interface and software enabling you to examine, analyze and compare your diving experiences and your performance throughout them. All of your data can be converted into graphical representaions to eanble you to identify trends in performance or to highlight areas of weakness that you should focus upon.

The Suunto Vyper: Summary Review

The Suunto Vyper is a a stalwart of Suunto’s dive computer range these days. It’s not the flashiest of models but its reliability is undisputable… just ask ask anyone who owns one. Although it has some advanced features and is a fairly tough model, it is most likely to appeal to the advanced recreational SCUBA diving market.

As with Suunto’s D9 and D6 models, the Vyper uses the same Reduced Gradient Bubble Model (RGBM), which considers the possible formation of small gas bubbles within body tissues.

The Suunto Vyper is very simple to use and consequently extremely user friendly: its three button configuration enables you to navigate through the menu options quickly and easily. Suunto’s Vyper is also easy to read even in extremely dark conditions due to the power of its electroluminescent display. This is of course always a useful feature for night or wreck dives. All the dive information that the Suunto Vyper outputs to its owner is logically presented and very clear to understand making it very safe to use.

In short, the Suunto Vyper is a great model for those who do not want to pay the earth for a lot of stuff they will seldom use. However, it will still provide more than enough features for most divers and most diving environments.

The Mares Nemo Wide is one of Mares’ offerings in the dive computer niche. Mares claim that the Nemo Wide is “the best interface between man & sea”.

Is it actually so?

The Rationale Behind the Nemo Wide

The design brief for the Nemo Wide was to create a dive computer that was easy to read and reliable, that promoted diver safety and was intuitive to use. Has this been achieved and if so how?

The Mares Nemo Wide dive computer has a very large display (the reason it is called the Nemo Wide). The large display means that there is plenty of room for the large digits that make reading the Mares Nemo Wide easy.

Combined with a strong back light and the brightness of the digits on the display itself, there are not many dive computers available on the market today that can claim to be as diver friendly in terms of readability.

The Nemo Wide is also very easy to use dive computer. It is ergonomically designed to make operation of the computer simple through its four large buttons: Mares calls this its “Easy Access System”.

At a Glance Features of the Mares Nemo Wide Dive Computer

• Maximum depth 492 feet (150 meters).
• A wide face with a high contrast display.
• Large digits make for easy reading.
• 170° viewing angle.
• Intense backlighting.
• Mares 4 button “Easy Access System”.
• Mares-Wienke RGBM: a new algorithm designed to reduce risks of micro-bubble formation.
• Multiple dive modes: bottom time, Nitrox and air.
• Residual nitrogen clear.
• Digital and analog ascent rate readout.
• Deep and safety stop functions.
• Logbook function stores 38 hours of dive information.
• Audible alrams.
• Altitude progams included.
• Usable in salt and fresh water.
• Tough, mineral glass face.
• User replaceable alkaline batteries.
• Upgradeable software.

Summary Review of the Mares Nemo Wide

The Nemo Wide is possibly one of the most usable and user friendly dive computers you can buy.

Its display could not be clearer and can be viewed easily from multiple angles.

With the many advanced features and functions inbuilt as well as its robust build and advanced ergonomic design, the Mares Nemo Wide is a dive computer created to withstand the toughest of diving environments.

Suunto creates another winner.

The Suunto D9 is the first dive computer in the world to integrate wireless cylinder data reception and digital compass technology…

… it also comes in a stunning titanium casing! How do you like those apples?

What Are The Main Features of the D9?

Like the Suunto D6 the D9 features the following:

• Complete timepiece functions
• Full decompression stop information
• Adjustable Suunto Reduced Gradient Bubble Modelling
• Ascent rate indicator
• Air, Gauge and Nitrox operating
• Integrated digital compass
• Audible alarms (including a maximum depth alarm)
• Numerous memory settings
• USB compatible PC interface and software

Unlike the D6 the Suunto D9 has:

• Wireless transmission
• Optional luxury Suunto titanium strap
• Gas changing (3 mixes 21-100%)

The Suunto D9 incorporates all the vital information you need on your dives, such as time, depth, tank pressure, direction and decompression status. The principal benefit of this is you have just one instrument to monitor rather than several, which can significantly improve your dive experience. However the D9 can of course be of use to you on land: the D9’s integrated digital compass does not just function underwater and neither does it stop telling the time!

Monitor Your Tank Pressure and Air With the Suunto D9

The Suunto D9 has an optional wireless transmitter, which can help you to monitor the pressure in your tank and your consumption of air. Consequently, the D9 is able to give you real-time information (graphically or numerically) about how much air you have left.

Gas Switching

The Suunto D9 can be used with up to 3 gas mixes (21-100% oxygen) enabling you to switch gases during your dive. Like the Suunto D6 dive computer, the Suunto D9 calculates decompression information through Suunto’s Deep Stop Reduced Gradient Bubble Modelling (RGBM). Suunto RGBM facilitates iterative deep stops as opposed to a single safety stop in cases where you intend to deep dive (you can wear your Suunto D9 up to 200 meters (660ft).

Suunto D9 Dive Profiling

The D9’s digital logbook will give you a real time graphical representation of your dive whereby you can analyze and assess factors such as tank pressure and water temperature.

Stylish Suunto D9 Titanium Casing and Strap

If you thought the D6 was an attractively packaged dive computer (it is) the Suunto D9 titanium model will blow your socks off. The D9’s titanium housing is simply stunning.

A dive computer that ticks all the boxes, the Suunto D9 might just about be the coolest diving gadget your money can buy.

Rating:

The Suunto D6 is a specialized dive computer designed for wear on the wrist. It is an advanced dive computer built for demanding dives and dive locations.

What Are The Features of the Suunto D6 Dive Computer?

• Full decompression stop information
• Ascent rate indicator
• Adjustable Suunto Reduced Gradient Bubble Modelling
• Gas changing (2 mixes 21-99%)
• 3 operating modes – Air, Gauge and Nitrox
• Fully integrated compass (digital)
• A host of audible alarms (including a max-depth warning)
• Dozens of memory settings
• PC interface
• Eyecatching black or metallic strap

Versatile and Robust: Suunto’s D6

D6 dive computers are literally packed with functions to make your diving experiences more safe. During all points in your dive the Suunto D6 will help you to manage your depth and times as well as providing you with constant directional data.

The D6 and Suunto’s RGBM

The D6 also helps you to manage decompression stops to get the most from your dive. Suunto’s Reduced Gradient Bubble Modelling algorithms allows you to select a deep stop model enabling iterative stops at depth instead of a single safety stop. This gives you maximum enjoyability with maximum safety.

The Suunto D6 and the Suunto Dive Manager Software Suite

The Sunto D6 dive computer is able to store data about your dives for you to analyze your performance later on your PC. Suunto enables this by providing the Suunto Dive Manager software online, free of charge.

The major benefit of the Suunto Dive Manager is that it can help you to create a more detailed account of your dive to add to your logbook.

The Suunto D6 is a highly recommended piece of kit for your dive.
