The PRO-TEC Screecher Alarm is a handheld personal safety alarm. Instead of shooting a spray that could accidentally burn yourself, the Screecher sends a super loud 116 dB (louder than an air horn) screech that can be heard from 1/4 mile away. It’s made to scare off attackers by attracting the attention of others. All you have to do is point the nozzle at the attacker, and press down on the cap!
