What is Edge Dive Computer Simulator?

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...

The Edge (Electronic Dive GuideTM) 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.
