Being able to find the way in even the worst weather conditions is important to many people, especially those on boats or in rugged terrain and waterproof binoculars is almost a necessity if you are out on the water often. You should also consider the diameter of the lens for its light gathering capability as weather conditions will play a role in how well they deliver an image.

Since visibility in rainy, or foggy weather will probably be limited high magnification may not be very useful, a set of 7X50 waterproof binoculars will be a good choice with the ability of the 50mm lens to produce an image under low light conditions being slightly above average while still being light enough to handle easily with comfort. The seven power magnification should be effective under wet weather conditions.

Keeping A Grip On Your Visual Aids

A good pair of waterproof binoculars will also have a covering with a non-slip grip to help prevent them from being dropped while you search the waters for navigational markers or other boats, or while hunting in the wet woods looking for game or your way back to the hunting camp. Also make sure the lanyard is secure to help keep it from falling from your grip.

Most waterproof binoculars are nitrogen purged to remove air with o-rings to help seal out moisture and are rated for certain degrees of waterproofing. For example, you may see them listed as waterproof to ten feet, which basically means that if they are submerged in water less than 10 feet deep, water should not penetrate the seals and get into the inner workings of the waterproof binoculars.

Most waterproof binoculars are of the roof prism design as the ferro prism binoculars with their offset lenses are tougher to present a water barrier. The straight barrel of the roof prism design makes them easier to keep water out, although the price will usually be higher for this design.

Keeping in mind the purpose of your buying waterproof binoculars is to use them in harsh weather conditions, the usually seven or eight power magnification is also good for general use binoculars.
