Title: Evaluation of the Scubapro MKlO and MK2O SCUBA Regulators for Use In Cold Water.
Author: Clarke, JR; Rainone, M
Abstract: NEDU tested the breathing effort and susceptibility to freeze-up of the Scubapro MKl0 and MK2O SCUBA regulators. The regulators were tested in 28 deg F (-2 deg C) salt water, at depths to 198 fsw (60.7 msw). Five samples of each model were tested. The probability of regulator failure was computed from the number of cold induced incidents, and the time to failure for each incident. Under these rigorous conditions, the probability of failure for the Scubapro MK2O was relatively high, hut was lower than in the MKlO. There were a large number of high breathing pressure events during the resistive effort measurements in both regulators at a 1500 psi supply pressure. Performance was improved at 500 psi supply pressures. Neither the Scubapro MKlO nor the MK2O is recommended for Navy use in sea water at 28 deg F and depths to 190 fsw. (MM)
