Storm Safety Whistle

Published in the August 2008 Issue Published online: Aug 26, 2008

The loudest whistle you can buy, even if it's drenched. Special self-draining chambers quickly purge water so it can sound a blast many times louder than U.S. military whistles. You can even hear it underwater. Made out of plastic, it has easy-to-grip ridges. Available for $9.49.
