Exploring under the water can be a fascinating adventure and experience to behold.

Descending into the depths of the unknown gives you a thrill, as you never know what you're going to see or find. Perhaps you have aspirations to find buried treasure or you're simply enamored with the opportunity to study underwater life. Whatever the reasons, you're going to need some type of monitor to ensure that your trip is as safe as possible, so that you avoid getting lost or experiencing when you decide to surface. While it's possible to dive without a dive computer, this little device will provide you added assurance for your safety and you'll be glad for having made the investment.

A dive computer is a small, watertight, battery-operated device housed in a pressure-resistant case and sometimes worn around the wrist (like a watch). The computer is designed to measure the time, depth, and ambient pressure of a deep dive under the water. In so doing, the computer ensures that a safe can be calculated and conveniently displayed back to the diver in order to avoid complications when surfacing. In other words, once a diver has spent a certain amount of time at a particular depth, after which a direct ascent (without stopping) would be unsafe or inadvisable, it is the dive computer's job to calculate an algorithm (a self-contained and step-by-step set of operations to be performed) that is based on the surrounding water pressure and time input to estimate when a no-stop ascent is no longer possible. Part of the calculation for this algorithm involves the measurement of inert gases that have dissolved inside a diver's tissues at a given point.

An inert gas is defined as one that does not go through a chemical reaction under particular conditions. For a diver, an inert gas is part of the breathing mixture that is not metabolically active. Once the dive computer has calculated this algorithm, it then estimates which decompression stops will need to be made by the diver during his ascent, at particular altitudes, and for how long. This process minimizes the chances for decompression sickness. So what types of information can a dive computer display?

Most dive computers feature for easy viewing in the water. Firstly and most important is the no stop time, which is displayed as the amount of time that a diver can remain at his current depth without the need to make decompression stops on the way up to the surface. The computer will also display the current depth and the total elapsed time for the dive. Some dive computers can also display total ascent times and the temperature of the surrounding water, and they have audible alerts when a diver is ascending too quickly or when a decompression stop has been missed. A Brief History Of The Dive Computer Up until the early 1980s, recreational diving was learned by leveraging.

Because these tables were not based on multi-level diving profiles, algorithms were produced to account for changes in nitrogen uptake when a diver's depth was constantly changing. These algorithms were not computer-accessible until the invention of the. Rather than showing a decompression plan, the Orca Edge would display a safe-ascent depth instead. In 1983, Austrian biologist Hans Haas innovated the first decompression diving computer called the DecoBrain, which was capable of displaying the same information that most modern dive computers display today. Around the same time, Orca Industries released the Orca Edge, which became the first commercially available dive computer.
