Dive computer

Dive Computer is a device used by underwater divers to measure the time and depth of a dive so that a safe ascent profile can be calculated and displayed so that the diver can avoid decompression sickness.

Overview

A dive computer is a type of computer that is specifically designed to be used by scuba divers. It is a crucial piece of equipment that helps divers monitor and manage their dive profiles to avoid decompression sickness, also known as the bends. The dive computer provides real-time information about the diver's depth, dive time, and ascent rate, among other data.

Function

The primary function of a dive computer is to calculate and display the amount of time that a diver can safely remain at their current depth without needing to perform decompression stops during their ascent. This is known as the no decompression limit (NDL). The computer continuously recalculates the NDL as the diver ascends or descends, taking into account the changing pressure and the diver's breathing gas.

Types of Dive Computers

There are several types of dive computers, including wrist-mounted computers, console computers, and air-integrated computers. Each type has its own advantages and disadvantages, and the choice of which to use often depends on the diver's personal preference and the type of diving they plan to do.

Safety

While dive computers are an essential tool for divers, they are not infallible. Divers should always have a backup plan in case of computer failure, and should never exceed the limits set by their computer. It is also important to remember that the computer's calculations are based on a theoretical model, and individual divers may react differently to decompression than the model predicts.
