S.O.L Survive Outdoors Longer Rescue Howler Whistle

Traditional whistles rely on a small ball, or 'pea,' inside the chamber to create sound. In freezing temperatures, that ball can freeze to the casing and stop the whistle from working, whereas a pea-less design like the Howler ensures consistent, reliable sound regardless of the weather.

This whistle produces a 100-decibel sound, which is designed to cut through ambient outdoor noise. Under optimal conditions, the sound can carry over a mile, making it an effective signaling tool for search and rescue scenarios.

The whistle features a compact, slim design intended to be stored easily in a pocket or pack. While it does not include a lanyard, it is small enough to be attached to a zipper pull or clipped to a gear loop.

Yes, the whistle is waterproof. Because it lacks internal moving parts like a pea, it will function perfectly even after being submerged or exposed to heavy rain.

Each purchase includes two whistles, allowing you to keep one in your primary pack and another in a backup kit or on your person.
