Title: ORCA's new Delphi computers: Impact on the diving community
Author: Heinmiller, PA
Abstract: Delphi Systems Dive Computers are the third line ofcomputers from ORCAIndustries. Beginning with the EDGE in 1983, and continuing with SkinnyDipper in 1987, ORCA has led the industry in the development of dive computers. Delphi Systems continue the ORCA tradition with a user changeable battery, instinctive display design, and the time-tested ORCA Decompression Model. Delphi adds tank pressure measurement, altitude operation, and simple graphics to SkinnyDipper-style operation. Inside every Delphi is a permanent memory of the last 35 hours of underwater time. This "black box dive recorder" stores maximum depth every 2.5 minutes, and is not damaged when the battery is removed. Data recovered from the recorders will be assembled as a database at ORCA, and then donated to the Divers Alert Network (DAN) for distribution and analysis. In the analysis of the data, ORCA will be able to provide comprehensive statistics on computer diving bends incidence, as well as validation and modification of the decompression model. After three years of the Delphi program, over one million hours of underwater profiles will be accumulated. The collection of owner information and actual, not predetermined, profiles will greatly advance the study of decompression in recreational diving.
