The Best Marine Binoculars Under $500

Factors to  Consider Before Buying Marine Binoculars

Below are factors to take into consideration before you purchase marine binoculars.

  • The Magnification Power

As we all know, been on a boat at sea is not the same as being on the land. In the ocean, as the boat or ship movements affect the way you see things especially if you are looking at them through the lens.

So the magnification power of the binoculars is important to be able to see clear images from far even when your boat is shaky on the sea waves. Magnification power is the ability of the binoculars to reduce the apparent distance of the object to you.

This figure is usually indicated in numbers. With  Example been 7×50 mm. The 7x indicates the magnification of the lens and the 50mm been the objective lens diameter. The 7x magnification is mostly preferred by the mariners because a  platform such as a boat is not stable and is easy to manage on hands. A Much higher magnification may result in shaky images.

The objective lens diameter size can affect the bulkiness of the binoculars, The bigger the diameter, the higher its ability to gather more lights from outside and from afar. So, 50mm is the optimal objective lens size preferred for marine binoculars.

  • Waterproof, fog proof and floatable

When dealing with water you can’t always be that safe. The waterproof feature ensures that your binoculars don’t get spoiled when they accidentally drop inside the water and their ability to float will help you recover them as they float on the water without drowning. Having floating straps handy is great as well.

Bad weather conditions can produce fogs which can also affect your optics vision. So because of that these days, most manufacturers of marine binoculars put argon/nitrogen inside the tube and seal the O-ring to prevent the fogging.

  • Compass

One can easily lose their bearing when inside the sea. Because of that these days, some binoculars come with an inbuilt compass. Although not necessary for some people, this feature just comes in handy if you want to know the bearing of objects.

  • Stabilization

If you are not satisfied with the 7x magnification of the binoculars. Then getting ones with an extra feature such as a stabilization factor is not a bad idea. It will help you get a steadier view of things.
