A dive computer, personal decompression computer or decompression meter is a device used by an underwater diver to measure the elapsed time and depth during a dive and use this data to calculate and display an ascent profile which, according to the programmed decompression algorithm, will give a low risk of decompression sickness.
The Shearwater NERD was released at Dive 2013 in Birmingham, UK. [19] Shearwater Perdix in compass mode. In 2015, the Perdix wrist mounted dive computer was released. The Perdix is similar to the Petrel but has a 30% longer battery life and a thinner and lower profile. [20] The computer was named after the grey partridge Perdix perdix. [21]
The personal decompression computer, or dive computer, is a small computer designed to be worn by a diver during a dive, with a pressure sensor and an electronic timer mounted in a waterproof and pressure resistant housing and which has been programmed to model the inert gas loading of the diver's tissues in real time during a dive. [31]
The Orca Edge was an early example of a dive computer that ran a real time algorithm. [2] Designed by Craig Barshinger , Karl E. Huggins and Paul Heinmiller, the Edge did not display a decompression plan, but instead showed the ceiling or the so-called "safe-ascent-depth" and a graphic display of calculated tissue gas loadings.
In addition, each compartment may be able to tolerate more or less supersaturation than others. The final form is a complicated model, but one that allows for the construction of algorithms and tables suited to a wide variety of diving. A typical dive computer has an 8–12 tissue model, with half times varying from 5 minutes to 400 minutes. [61]
The US Navy has used several decompression models from which their published decompression tables and authorized diving computer algorithms have been derived. The original C&R tables used a classic multiple independent parallel compartment model based on the work of J.S.Haldane in England in the early 20th century, using a critical ratio exponential ingassing and outgassing model.
