Overview

Screech is a palm-sized personal-safety alarm. A high-output piezo array behind the green-ringed ports emits a piercing screech to deter a threat and draw attention, while a locking carabiner and braided leash keep it clipped to a pack, belt loop, or bag — always within reach on the trail or the walk home.
