Amazon: Cressi-Sub Archimede II Dive Computer

Summary

Pros: Dive Planning function for safely planning repetitive dives. Nitrox programmable for up to 2 gas mixes. Bar graphs for Residual nitrogen and Oxygen loading.
Cons: Only calibrated for salt water. Could be more user friendly. Always on (watch and calendar) so chews through battery life. PC interface software isn’t compatible with Windows Vista or Windows 7.
Recommended Uses: If you are a recreational or sport diver who won’t be doing decompression dives and you prefer to stay within conservative limits while diving, the Cressi-Sub Archimede II is a fantastic choice.

Full Review

The Cressi-Sub Archimede II is a wrist style, multi- function dive computer that can be used for either Air or Nitrox diving. It also has a gauge only mode, which when used for free diving displays only the current depth, maximum depth, dive time and ascent speed.

Features and Useability

The Cressi-Sub Archimede II has a 3 button operation which at first seems a little over complicated, but a good couple of practice runs on the surface should improve useability. The display is easy to read as the characters used are quite large and the screen layout is both logical and clear. Because backlight is on demand, energy use is negligible as backlight only activates for 5 seconds at a time. The battery is user changeable, and if the level gets too low, the Archimede II enters a mode which doesn’t enable you to use it for a dive. It also incorporates a watch and calendar function which is great, but also means that the computer stays on permanently, which degrades the battery life.

There are 3 dive programs available – Air, Nitrox and Gauge, with the Nitrox program allowing for up to 2 different Nitrox mixes to be used during the one dive. The Cressi-Sub Archimede II is also diver programmable to incorporate a more aggressive or conservative dive profile with a total of three settings, although even the most aggressive of these settings could still be seen as too conservative for some divers. If you’d prefer to stay on the safe side, then the conservative nature of this dive computer is perfect for you. It’s important to note that Cressi discourages the use of the Archimede II for decompression dives. If the no decompression limits have been exceeded during your dive, however, the current NDL icon is replaced by the DECO icon which will assist you with specific information related to decompression and surfacing safely.

This Cressi-Sub Archimede II uses a refined RGBM algorithm which penalises the diver less in colder temperatures or for faster ascent rates. Nitrogen absorption and release is continuously processed and when on the surface, the tissues Residual Nitrogen is represented in graph form. In fact there are 2 other graphs available as well – the Oxygen Loading bar graph shows the Central Nervous System 02 toxicity level, and the Ascent rate bar graph displays how fast you ascended, along with any alarms if you exceeded the recommended rate.

The Cressi-Sub Archimede II’s PC interface is an optional extra. Even without the PC download kit, though, the Archimede II is able to log a total of 60 dives with 3 different data displays for each. There is also a dive history function already included with which you can store up to 999 dives. The dive history displays data such as Total Hours of all dives, Maximum Depth reached during all dives and Total Number of dives. When you’re on the surface, you’ll have plenty of information to check and analyze in preparation for your next dive. Another feature you can use when you’re not actually diving is the dive simulator, which allows you to test potential dives without getting your fins wet!
