Dunkive 2 Pack 1.4oz Bear Horn Self Defense, Loud Air Horn for Bears, 120dB Heard up to 1/2 Mile Away, Air Horns for Safety for Wild Animals, Bear Alarm Scare Bears, Ideal for Hiking

I bought this to scare off coyotes that frequent my area. Not a smart move, but I took one out and tested it in my house. I held it a full arms length away from me and held it down for about a second. My ears hated me! It was super loud and worked very well! My ears had a continuous ring for over 5 minutes. So does it work? Absolutely! I would definitely recommend it! Perfect value for receiving two for the price. Very easy to use.

Small and convenient to go for a hike. It would be nice if it can be attached to the belt. Tested, really loud

Works for bears and humans. Believe me, I experienced it.

Consider this a deterrent. Easy to carry, and handy to have around camp.

Thank goodness I haven't had to use it, but I'm glad I have it on hand. We have a resident coyote that roams the neighborhood and although we have two large labs, it stares at us, like a challenge.
