Thank you for visiting our ebay store! We are born explorers. The eAlarm+ helps us explore with confidence. It is an ultra-compact emergency alarm, small in size but big in sound. Once you pull the pin, the device emits a 130 decibel alarm. The siren will sound continuously for 30 minutes unless pin is returned to device. The eAlarm+ allows maximum utility for those intending to use in the outdoors with a rugged rubber water-resistant shield. The extra bottom hook feature allows easy construction of a tripwire or campsite alarm.
