The Dive Computer

Computers do away with the need for some of the analogue equipment by consolidating them into a digital display that often has more detailed and accurate information

Aside from the snorkel and the exposure suit, one needs to shell out cash to buy a dive computer.

A dive computer, otherwise known as a decompression metre, serves the purpose of monitoring the moment and extent of a dive, specifically in terms of the depth or the distance of the diver from the surface and the length of time he spends under the water.

Thus, by having a dive computer, instead of a depth gauge or dive watch, the person can keep track of his decompression stops and speed of his ascent. Since the technology used in a dive computer is different from other traditional diving gears, features like temperature, pressure, and oxygen toxicity are typically included in a dive computer.

So how did the dive computer came about in the world of scuba diving? Basically, the origin of the dive computer can be traced to the conventional decompression metre, which was introduced to the public in 1972 by Scubapro. At that time, the device was in an analog form and had a simple design consisting of a waterproof casing embedded with a manometer, which signals the diver of decompression stops. Later, when electronics and personal computers were developed, the decompression meter became digital and was incorporated with more sophisticated features.

The Dive Computer

Today, modern versions of the decompression metre, now known as the dive computer, have LCDs that provide vital details on depth, maximum depth, remaining time until decompression stops, and total dive time. More advanced dive computers can even tell the diver, through the LCD or buzzers, of other dive-related information, such as ascent rate, water temperature, and dive profile, and expedition details including dive logs, maximum periods for subsequent dives, and time for plane boarding.

Most of today's dive computers operate on batteries and are sealed in a watertight cover. Since these computers calculate the pressure involved in diving and provide decompression schedules for safe expeditions, users, especially those who travel prior to or following a dive, should ensure that their diving computers retain the same pressure, atmospheric or otherwise, so that the equipment can properly and accurately read the diver's body and what it needs underwater.

There are various kinds of diving computers that are available in the market right now. When purchasing dive computers, you need to consider diving modes such as Nitrox, Air, Bottom Time, Free Dive and Gauge. You can also look for trusted brand names like Aeris, Oceanic and Scubapro. Before purchasing the model or brand that you like, it is suggested that you make a thorough research of this diving equipment and of course, spend some time familiarizing yourself with diving so that you can learn how to work and tinker with the functions and features of the equipment.
