The Ultimate Survival Techniques Hear-Me Find-Me Floating Combo caters for all sorts of emergency situations. The Hear-Me whistle will attract attention even if you're hidden by a thick, leafy tree canopy or in a cave. The Find-Me mirror lets you signal emergency crews even if you're out of ear shot. And the bright orange float will make you easily visible in the water. It all comes with a break-away lanyard so you won't lose it but you won't get hung up on rocks or trees either. Bring it it just in case when your adventure takes you to unpredictable off the beaten track places.
