(2 pack) Ozark Trail Boat Accessories Sports and Marine Safety Air Horn 3.5 oz.

This is the very small one but for me, seems to last forever. I only use it when, I need to. In other words, hearing something strange outside in the dark of night. Getting the attention of others. I never have but these would probably be a very handy item to keep in your purse or coat pocket. They're extremely LOUD and would get everyone's attention plus scare off an attacker.

Raccoons don't like it. That's why I got it. Raccoons were clawing their way into a wood sided shed in my yard. I ambushed them with the horn and they scattered. They came back in a couple of days and I did it again. They haven't been back for two weeks now so far.
