3 Function Survival Whistle, Olive Drab w-Lanyard
Don't go to camp without this 3 Function Survival Whistle from Red Rock Outdoor Gear. If you're in need of help and cold, this whistle will put off an ear drum piercing blast and tell you the temperature at the same time. And if that wasn't enough, there's a built in compass for navigation or backup.
