WW-3 Survival Whistle
ACR No. 2228 (2227/2231)
Meets USCG/SOLAS 83 requirements
U.S. Navy-specified sea-going whistle has an unusual flat design to prevent the whistle body from holding water and damping sound. As a result, this is the whistle you can hear loud and clear across great distances. Every life jacket, raft, and foul weather gear should have one attached. Complete with 18" (45.5 cm) of lanyard.
