The program Edge? Dive Computer Simulator is a simulator for the Edge
Dive Computer. The program simulates diving with the Edge for both no-
decompression and decompression situations. The program uses the same
decompression algorithms and shows the same display as the actual Edge
dive computer.
This text serves the purpose of a manual for the program, but is
actually an addition to the owner?s instructions manual for the Edge
dive computer. The reason is that familiarity is assumed with the
usage of dive computers in general, and possibly with the Edge dive
computer in particular. Also, this text is not intended to be a
replacement for the Edge owner?s instructions manual.
### The Edge Dive Computer
The Edge (Electronic Dive Guide?) is manufactured by Orca Industries.
The Edge Dive Computer, �1984 by Orca Industries, is a compact
submersible computer which provides the diver with information to plan
a dive, it is a precision depth control, dive timer and surface
interval timer. It handles single dives as well as repetitive dives.
The Edge calculates continuously the decompression status based on the
diver?s individual dive profile, and gives the diver a continuous
readout of this status.
The simulation program uses the same decompression model as the Edge,
i.e. the Haldanian decompression model which is similar to the Navy
standard air decompression model. The model is based on the uptake and
elimination of nitrogen in twelve tissue groups with half times
ranging from 5 to 480 minutes. As for the Edge, the update interval
for the decompression status is 3 seconds.
