Be leery of manufacturer claims. Many use terms such as water resistant, weatherproof, or some other proof to describe attempts to protect their binoculars against the elements of weather. Since we often have no guidance as to what this "proofing" really means, the best suggestion may be to insist only on waterproof and ignore all other claims as being lesser version of proofing.

Sealing is the most important aspect of waterproof binoculars. Proper sealing denies access to the interior of the binoculars by foreign objects. The type sealing done, the process used to seal, and the care you provide your binoculars goes a long way in obtaining a true waterproof binoculars that will function properly for years. An article I recently read suggest one could waterproof their own binoculars by adding beeswax around the rim edge of the eyepieces. I don't know your skills at home remedies, but I prefer to add a few extra dollars and purchase a pair of binoculars guaranteed to be waterproof. Not only does this provide me with a warranty to cover any problems associated with waterproofing, but I also have not dripped beeswax all over a perfectly fine set of binoculars.

Unfortunately you cannot just pick up a pair of binoculars and determine how well it has been sealed, since sealing is done internaly to the binouclars at its construction. One must depend primarily on the manufacturer's claim to waterproofing. But there are a few points one can use as guidance.

First. If the binoculars has been advertised and guaranteed as being waterproof, then generally the manufacturer is standing behind that claim.

Second. Have a feeling for the manufacturer's credibility. Binoculars from brand name manufacturers typically come with written warranties that define their waterproof coverage.

Third. Always ask if the manufacturer will correct any waterproof problems free of charge. Most will not charge for any repairs or resealing of a problem waterproof binocular. Generally you will have to cover the shipping charges.

Binoculars typically retain their waterproof status under normal usage, during rainy weather, after a drop into a wet boat, or even after a fall into a water puddle. But don't push the extremes of water and water pressure. A drop into a few feet of water may be all right - if you fish the binoculars back out immediately and don't constantly repeat that process. However, submerging binoculars into water for any length of time will compromise its waterproof capabilities. Also, be aware that the depth of submersion can also compromise the binoculars ability to hold its waterproofing. Water pressure increases with depth and will seek to force itself into the chassis of the binoculars.

Using a few precautions will allow your waterproof binoculars to serve you well for years. Handle your binoculars with care at all times. Don't bang or bump them during use, as the jarring will tend to loosen the internal waterproof sealing. When not in use protect your binoculars with rain covers, lens caps, and place them in a protective carrying case. Avoid abrupt weather changes, such as walking into a warmly conditioned lodge after an all day affair outside in sub zero temperatures. Allow the binoculars to gradually adjust to temperature changes. Waterproofing is a feature to consider when purchasing binoculars, and a condition that requires care and maintenance during its lifespan.
