Sometimes yelling for help is not good enough and that is why we recommend The Screecher Personal Alarm.
It uses compressed air to emit a very loud alarm that is ear-piercing and attention grabbing. The blast is readily recognized as an emergency call for help with its high-pitched shriek that can be heard up to a quarter mile away.
The Screecher Personal Alarm is small enough to fit inside a pocket or purse and has a push-top activator. The unit will emit approximately 30 short blasts.
