This sealed three pack of cartridge flares is an interesting look at the days before cell phones, GPS and modern navigational aids. The directions recommend waiting until after dark, then shooting one flare and three shots every 15 minutes while hoping for rescue. It would be much more productive to just get out your compass and walk back to the truck. These would fit a 30/06 rifle and might burn down the neighborhood, I recommend them for collecting, not for shooting. Free shipping.
