Photo illustrating Dive Computer

Device that does all the hand work for you. No more multi level diving calculations, no more PADI wheel - based on empicic data and theoretic models - not necessarily always right but a great help for repetitive diving. Beeps often. Dive computers address the same problem as decompression tables, but are able to perform a continuous calculation of the partial pressure of inert gases in the body based on the actual depth and time profile of the diver. As the dive computer automatically measures depth and time, it is able to warn of excessive ascent rates and missed decompression stops and the diver has less reason to carry a separate watch and depth gauge. Many dive computers also provide additional information to the diver, for example, the water temperature, information on the diver's oxygen toxicity or the pressure of the remaining breathing gas in the diving cylinder.
