ACR 0.2 oz Emergency Whistle

"The flat design of this 0.2 oz emergency whistle makes it ideally suited for wearing on a neck lanyard..."

About the ACR WW-3 Emergency Whistle

The WW-3 Whistle was developed for the US Navy and is USCG approved. Its pea-less design and high impact plastic means that it's durable and rugged enough for extended backcountry use. It is one of the loudest emergency whistles available, audible from great distances.

Its unique flat design prevents the whistle from holding water, which unless you are planning on using it to signal an emergency while drowning in an alpine lake, won't be a particularly useful feature for the backcountry hiker (adventure racers, backcountry canoeists and packrafters may appreciate this feature, however!).

The reason we really like the ACR Emergency Whistle's flat design, however, is that it's virtually unnoticeable when hanging off a lanyard (included) around your neck, unlike bulkier whistles like the Fox 40 Mini Whistle.

We compared the performance of the ACR WW-3 Emergency Whistle to the Fox 40 Mini Whistle (another backcountry favorite), and here's what we found: The ACR Emergency Whistle requires less air to blow at a particular decibel level than the Fox 40 Mini Whistle. In addition, the maximum db output of the ACR Emergency Whistle is greater than the Fox 40 Mini. We think this performance, combined with the flat, lay-next-to-your-chest-and-not-be-noticed-design makes the ACR Emergency Whistle the ideal whistle for the backcountry traveler.

Oh yeah, did we mention that it is lightweight?!

Freaks that sit with their feet dangling off the edge of the ultralight cliff will want to replace the stock lanyard with AirCore 1 Spectra Accessory Cord.
