The Davis Key Buoy - Emergency Buoy for Your Keys

My uncle TJ always on a trip offshore to fish, never have I heard he drop his keys into the water, but never say never. The Davis Key Fob is a keychain with the ability to inflate a small pop of tube to make your key float back up to the water surface when you drop it into the water. The tube will rise up to 14 inches above the water so you will be able to pick it up easily. Once it has inflate, you will not be able to use it again or deflate it as this keychain works the same way as car airbags, a one time pop. The keychain cost $6.99 and you can buy them from Landfall Navigation.
