All Leica full-size binoculars are waterproof to a depth of up to five metres (16.5 ft). But, if the worst comes to the worst, it's good to know there's the floating neoprene carrying strap to prevent them sinking in the first place. In bright and ultra-visible orange, it offers maximum security against the loss of your valuable equipment when by, in or on the water. The floating carrying strap is the best solution for preventing total equipment loss when observing close to, on or in the water.
