Emergency Response International

“In areas near fast-moving streams, high windy ridges and other environments where background sounds may prove conflicting to search efforts, the whistle’s unique sound characteristics insure clear distinction of rescuer signals and no mistaken perception of natural sounds… We will only be offering equipment that we have tested and that we believe is superior in its performance. It is our recommendation that your Signal 1 – Tri Power Whistle be a “must carry item” in our list of essentials for the outdoors.”
