ACR ELECTRONICS WW-3 Res-Q™ Whistle
Developed to locate overboard persons, the compact WW-3 Res-Q™ whistle meets USCG requirements and issues a shrill dual tone, up to 100 decibels, that is audible over great distances. The unique flat design keeps it from holding water and the WW-3 Res-Q™ whistle comes with a 31.5 inch lanyard for easy attachment to life jackets, rafts and foul weather gear.
