Hello readers:
Old Meters
The very earliest computers, such as the 1979 DecoBrain, were actually time-depth recorders that referenced dive tables internal to the device. In other words, they actually did not calculate gas loads in compartments and calculate ascent criteria. They contained look-up tables.
If something occurred that was not in the table, they would respond with an out of range warning and leave divers to fend for themselves.
Then there was the ScubaPro (Bend-O-Matic) that had a bladder and porous plug. It was a pneumatic device and was prone to errors many errors.
Electronic Calculators
The meters today, starting with the Orca Edge, will actually calculate gas loads. The dives described in the paper would not be allowed. The final dive would need a drastically truncated bottom time to be safe.
The authors assertion that some meters allow these dives eludes me as to its meaning.
