The DIR philosophy is opposed to the use of dive computers. Most other technical diver training agencies recommend using two — a primary and a backup. Doing it Right: The Fundamentals of Better Diving page 119 lists 13 reasons why DIR consider dive computers to be bad.
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 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.
