Carpenter was trained by Robert A. Barth. Shortly before the experiment took place, Carpenter had a scooter accident on Bermuda and broke a few bones. The crash ruined his chances of making the dive.

In 1979 on a diving trip to the Bahamas, he was introduced to the concept of multi-level diving and the technique of repet-up s, which was in use by commercial divers as a way to make more effective use of the Navy tables for multi-level diving, though there were some theoretical uncertainties with the system, as the Navy tables of the time used six tissue compartments, but only considered the ...
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 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.

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.
Dive profile of an actual dive as recorded by a personal dive computer and displayed on a desktop screen using dive logging software. In this case depth is in metres. Personal dive computer display of dive profile and log data. A dive profile is a description of a diver's pressure exposure over
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.
It has been argued that the lack of necessity to purchase a dive computer reduces DIR costs (Jablonski: "Dive computers are expensive, and prevent divers with limited resources from purchasing truly useful equipment" [92] "), it has also been argued that the lack of a dive computer adds to the risk of diving for recreational divers.
