Comparison Evaluation of Explosive Diver Recall Devices

Abstract : NEDU evaluated non-developmental explosive diver recall devices for inclusion on the Diving Equipment Authorized for Navy Use List. The devices tested were: Broco MK 2 MOD 0 and MOD 1, Hands Fireworks SC-81 and SC-810, Compact Energy, Ltd. N1 MK 1, and the military M-80. Characteristics that were evaluated include acoustic output, fragmentation production, human factors, operational reliability and end item cost. Based on the comparison of these factors, the Broco MK 2 MOD 0 is deemed most suitable for Navy SCUBA operations where an explosive type recall device is required. Also, due to safety and reliability problems, it is recommended that the M-80 (NSN 1370-00-028-5252) be removed from the ANU as soon as suitable substitutes are in the fleet.
