Losing the trail, or getting turned around can happen to anyone. Don’t be caught without the ultimate survival tool. This super whistle emits shrills of extreme decibels not capable of ordinary whistles. Search and rescue teams will hear your call from up to a mile away in ideal conditions. But, you’ll probably never need a rescue since you’ll always know which way to go with the included magnetic compass on the side of the whistle. A Fahrenheit thermometer also allows you to monitor the temperature and weather to ensure you build the optimal shelter for the conditions if forced to spend a night alone in the woods.
