Back in the early 80’s the commonly used tank in Australia was an Australian manufactured AL88, and were the only tanks I used for many years.
Dive 33 after my O.W.course was 30 metres for 20 minutes
Dive 39 was to 34 metres for a total for 22 min
Dive 43 was to 37 metres for a total time of 23 minutes
Dive 54 was to 40 m for 18 min as part of a Cave Diving Association of Australia Cat 2 course.
All dives were done on a single 88, no redundant air supply. In fact I am not even sure if I had an octopus. Part of the CDAA test was to buddy breathe while the out of air diver was following a guide line, so they may not have required an octopus in those days.
None of this was exceptional in anyway for the time, it was quite simply what was done.
