ACR Electronics WW-3 Survival Whistle - USCG/SOLAS Compliant Dual-Tone Rescue Whistle

The ACR Electronics WW-3 Survival Whistle (part number 2228) is a compact emergency signaling whistle designed to get attention fast when someone has fallen overboard or needs rescue on land or at sea. It issues a shrill dual-tone blast audible up to 100 decibels, making it far louder and more attention-grabbing than a standard round whistle. The WW-3 uses a unique flat design that keeps water from collecting inside the body, so it stays ready to sound off immediately even after submersion.

Originally developed for the U.S. Navy, the WW-3 is also used by NASA, major airlines, and shipping companies, and it meets USCG and SOLAS requirements, including the SOLAS 83 mandate. It comes complete with an 18 inch (45.5 cm) lanyard, letting it attach quickly to life jackets, vests, foul weather gear, ring buoys, rafts, or keychains. Its small size and flat profile mean it can be clipped onto safety gear without adding bulk, and it is built to hold up to the demands of marine and outdoor use.

Whether stowed on a life jacket, a raft, or a keyring for hiking and camping, the WW-3 gives boaters and outdoor users a reliable, USCG-compliant way to signal for help when it matters most.
