The WW-3 Res-Q(c) Whistle (EDMO# 2228) is developed for the U.S. Navy to locate over-board persons. This signal whistle produces a 102 dB, dual tone shrill that can be heard over long distances. The flat design prevents the whistle from holding water. Included is an 18-inch lanyard to attach to life jackets, rafts, and foul weather gear.
