Here is a chart of regulator performance from tests conducted by US Antarctic Program from '89 thru '95. The data was accumulated by Jeff Bazanic and Jim Mastro. All dives were conducted in McMurdo Sound, Antarctica. Water temp range -1.9C to -1.2C. All failures were due to free flow. FFM dives were done in Dry Valley lakes. Water temp 0C. Based on these tests, USAP now issues Maximus regulators. As mentioned earlier, we have had NO failures for past two seasons having made approximately 2000 dives on the regs during that time. Hope the information is of value.
