Guard Dog Security Compact Air Horn 1.4oz

A compact 1.4 ounce air horn built for signaling. One press puts out a blast that carries up to a mile, which covers the situations where a voice will not reach: open water, a job site, a trailhead, a stalled car on a dark shoulder.

It runs on compressed air, so there is nothing to charge and nothing to aim. Small enough to ride in a glove box, a boat bag, a pack lid or a dorm room drawer. Noise by itself breaks up a lot of bad situations, and it works the same for anyone regardless of size or training. Keep it where it can be reached without digging.
