Waterproof binoculars should be able to stand up to the difficult marine environment and waterproof boating binoculars are of utmost importance as too are night vision equipment that can be used for search and rescue missions. The Pro Mariner waterproof 8×30 are ideal waterproof binoculars and Pro Mariner’s range of waterproof binoculars are innovative and effective to use on board, having rub-coated lenses that incorporate BAK4 prisms that are conducive to retaining extra light while at the same time, reducing eye glare.
Another type of waterproof binoculars is the Magellan 7×50 Marine which is all weather, rugged binocular ideal for use in the roughest waters and extreme weather conditions. It also includes an illuminated compass as well as an internal Rangefinder. Bushnell sets the standards for waterproof binoculars with its H20 10×40 WP/PF Porro Prism, which is reasonably priced and is completely O-ring sealed as well as being nitrogen-purged for waterproofing and fog proofing, in any kind of weather conditions.
The first time buyer of binoculars may be totally confused by the mind boggling array of options available, such as magnification, size, light factors, waterproofing, anti-reflective lens coating, viewing angle, rubber armoring and integral compass. But, there are a few simple rules that should be followed when purchasing waterproof binoculars and these include magnification, size of the objective lens, centre focus, fixed focus or individual focus, spectacle wearers, and quality and lens coating.
For magnification, a 7x magnification is the maximum requirement for waterproof binoculars that can be safely handled at sea because of the motion of the boat. The next thing to decide is the size of the objective lens which is the wide lens at the far end from where light gets transmitted to the binocular and for marine use; this should be 50mm in diameter. The smaller the wide lens, the smaller is the size of the binocular. In addition, most binoculars have a viewing angle of seven degrees and are quite acceptable for marine use.
The waterproof binoculars that are completely waterproof will cost about two hundred US dollars and to check whether the binocular is indeed waterproof, there should be printed on the binocular, words that state that it is waterproof or nitrogen filled. In addition, most of the waterproof binoculars available today have individual-eye focusing systems and a great many come with soft rubber eyecups. In addition, one should look for clarity, brightness and comfort of use when selecting binoculars.
