Diving Light Submarine Scuba Flashlight with Battery Dive Light Waterproof Underwater Torch for Scuba Diving Night Snorkeling Pack 2

Important: Turn on the flashlight before diving, make sure the flashlight's head and bottom are screwed tightly in case of water floods into the flashlight underwater. (It is much easier to flood water into the flashlight as you couldn't screw the switch tightly underwater) Clean the flashlight with fresh water after each diving. Lubricate the switch and O-rings after each driving. Don't drop the flashlight on the beach, in case the sand goes into the switch. Take out the battery if you don't use the flashlight for a long time.
