There have been many advances in binocular technology over the last 20 years, making today’s binoculars more powerful, more stable and more durable than ever. Watertight technology has been one of the key innovations of recent times, resulting in waterproof and water resistant binoculars. Waterproof binoculars can function even after being fully submerged, whereas water-resistant binoculars will only be able to resist water for a while and will not function after being in very deep water.
Water-tight binoculars are often sealed air tight and cleansed with nitrogen. This means that they are not just resistant to water but also to temperature changes in the atmosphere. This ensures that the magnified image you see through the binoculars is unaffected by the clouding of the magnification lens, resulting in a clear and sharp image.
Some watertight compact binoculars are buoyant, allowing them to float. This makes them easier to retrieve from any deep water environment so they are ideally suited to marine activities. Water-tight binoculars are now often coated with rubber armour for shock absorption. Not only does this protect the binoculars from being dropped but also helps to counteract the threat of salt erosion. Along with the rubber armour, some water-tight binoculars also have extra gripping on their surfaces. This is to ensure a firmer grip in marine environments so that the buoyancy feature is not used too frequently.
