Staying true to their ""Live Safe"" mantra, Byrna is excited to introduce the Byrna Banshee: a military-grade, 130dB personal safety alarm capable of producing an ear-piercing alert that draws attention to you and thwarts potential attacks. It comes packaged with a carabiner that conveniently attaches to backpacks, purse straps, and pant belt loops for quick access during emergencies. It is durable and water resistant and the batteries are replaceable lasting up to one year. The Byrna Banshee is ideal for students, adults, seniors, and outdoor enthusiasts. Note: 130dB is equivalent to hearing a military jet aircraft take-off from 50 feet away.
