Counter Assault Bear Spray. Counter Assault can prevent animal-human conflicts using a non-lethal formula that does not permanently harm the animal. Only a small amount of Counter Assault is usually needed to arrest aggressive behavior. A blast of Counter Assault will often be enough to scare an aggressive bear away, but if not, the high volume, high velocity cone-shaped spray of burning pepper (3 million Scoville heat units) are sure to stop an attack. Nylon holster included.
