When looking for a pair of waterproof or marine binoculars, one needs to be very careful about which one to get. There are a lot of word games going on here. Truly waterproof binoculars are charged with dry nitrogen and specially sealed inside to be watertight, therefore, they can be emerged into the water and the performance will not fail. Some so-called waterproof binoculars are only water-resistant meaning they are ok when there is a splash.
