Dive Computers Reviews:

Here is a fact that divers should not let their worry-wart friends in on: each hour of diving is 36 to 62 times more dangerous than driving a car. Good gear and a cautious approach to scuba diving can help reduce the risk of injury from inhaling gases or aspirating water. But divers also have to be careful about descending and ascending too quickly. Decompression sickness is a real possibility, and it can be a painful and potentially dangerous one at that. A dive computer can be a life-saver; not only can it help you avoid the bends, it can help you monitor each aspect of your dive. A good diving computer helps you stay safe - but more importantly, it will help you take your eyes off your wrist, your mind off your depth, and your attention fully on the incredible scenery that is waiting for you below the surface.

What Can Diving Computers Do? - Diving computers are much more than sleek, sporty watches; they are safety tools first and foremost. As a safety device, scuba diving computers are regulated by the International Organization for Standardization, or the ISO 6425 standard. This means that every watch or wrist computer that is marketed as a diving computer has to meet these standards - or exceed them. These are:

*Unidirectional bezel with 5-minute elapses minute markings and pre-select marker to mark a specific minute
*Clearly distinguishable minute markings on the face
*Readability and visibility at 25cm, or 9.84 inches, in total darkness
*Running light indicator
*Magnetic resistance and accuracy to +/-30 seconds/day as measured before the test
*Shock resistance
*Chemical resistance
*Strap/band solidity
*End of Life (EOL) indicator on battery-powered watches
*The cases have to be adequately water and pressure resistant

Some other considerations to think about before you buy include:

*Style. You can choose from wrist dive computers or console models, which are attached to your other scuba gear with a hose. Each has benefits: a dive computer watch allows great freedom. You can check your measurements without stopping, just as you would check your watch. A console dive computer usually has a bigger readout and a pressure gauge, which wrist models do not.
*Nitrox? If you dive with nitrox, or plan to, choose a model that can monitor air mixtures to measure your intake of nitrogen. You can even find those that accommodate a trimix of helium, oxygen, and nitrogen).
*Audible warnings if you ascend too fast or near a limit. These can be user-set.
*Compatibility with your computer.
*Keep it simple. If you are a beginning diver, choose a diving computer that is simple and easy to use. Many veteran divers also depend on the simple models that are reliable and dependable.
*Do you want to be cool at the office or safe in the water? Dive watches do make excellent watches for sporty, chic men - if you want a dive watch that is more of a fashion accessory, that's fine. If you want one that will be a diving companion, check to make sure it meets the toughest criteria.
