Waterproof Binoculars Cost More, But They Are Worth It
ByIf you are planning on taking your binoculars out to sea, you’re going to want to make sure they are waterproof. Although a pair of fully waterproof binoculars will cost quite bit more than non-waterproof varieties, you will ultimately save money by not having to constantly replace them.
Waterproof binoculars are not simply made of a water resistant material such as rubber. Instead, the design of the internal components actually makes the binoculars waterproof. A hermetically sealed binocular is considered waterproof, while a nitrogen-filled binocular is also fog-proof.
The lenses must be sealed for the binocular to be waterproof, since most of the damage caused by water is done inside the lenses and prisms. If you suspect that your current binoculars may be mildewing, try looking through the wrong end, held a short distance from your eyes. You should be able to see if the clarity of the binocular has been compromised.
Fog-proof, waterproof and fully multi-coated lenses are features that you should look for in a pair of binoculars. If you can’t afford all these high quality features, realize that these three features will be found in the best binoculars. These binoculars resist getting fogged up inside because they are sealed off from the atmosphere outside and the inside is filled with nitrogen. Nitrogen gas provides a constant atmosphere in the sealed tubes of the binoculars. Because each tube is sealed, the nitrogen gas won’t escape and moisture won’t get in. Your lenses won’t get foggy.
You may have to pay a little extra for waterproof binoculars, so you’ll have to weigh the pros and cons for your situation. If you’re comparing a few different models, take into consideration that being waterproof is a plus, and maybe a deciding factor for you if you’re into boating or fishing or just being around water.
Manufacturers have gone from using a single coating of some of the optics to having multiple special coatings for each piece of glass, lens and prism. This takes more time and care at the factory, and so the more coatings the better and probably the higher price binoculars. Get the best quality optics that you can afford and you won’t regret it. Objects will appear bright with optimal resolution, fine contrast and color accuracy.
