Yes, studies have proven that air horns are a harmless but effective deterrent for bears, cougars, and coyotes. The Hornet rechargeable air horn will generate over 121 decibels of sound, more than enough to frighten-off these animals at a distance of 100 feet or even greater.
Field researchers working in bear country will use an air horn intermittently when traveling through the forest and underbrush to ward-off bears in the area before a chance encounter can even occur.
On one battery charge, the Hornet rechargeable electric air horn will offer over 35 minutes of sound at 121 decibels for this type of precautionary warning.
