CHOOSE THE RIGHT BINOCULARS:

When choosing your new sailing binoculars are the characteristics that give you the best return on your binoculars.
Below you can read about the different concepts and their significance.

Magnification

The magnification of a telescope is designated by the first number in the example. 7 x 50. The image in a 7 x 50 telescope could
magnified 7 times more than what the naked eye sees.
7 x magnification, the recommended magnification in a marine binoculars. Selecting a higher magnification can be difficult to hold the binoculars still enough to look sharp - especially when the boat is not at rest.

OBJECTIVE LENS DIAMETER

On a 7 x 50 binoculars are the 50 that indicates the objective lens diameter. The higher the number, the more light there. This is an advantage in bad light.
For marine use recommend an 50 mm lens, as this will give a good light in most conditions - there are binoculars with larger diameter, but the 50 mm allows a telescope in a good manageable size.

POINT OF VIEW

The viewing angle in degrees indicates the width of the image can be seen at a distance of 1000 m. For example. will a viewing angle of 6,6º provide a width of 115.3 m at 1000 meters distance.

LENS AND PRISM COATINGS

Blue coated: Improves sharpness and contrast.

Green multi coated: Improves sharpness, contrast and color. Green coated lens is ideal for use on the water. It allows maximum light transmission and reduce glare

Multicoated: Fully coated lenses, multicoated prisms for better brightness, higher contrast and sharper colors.

Fully coated: Enhances brightness and contrast.

Fully/multicoated: Both lenses and prisms are multicoated, giving the best possible light, the best contrast and the best colors.

Ruby Coated: Rubycoatede lenses filter out the glare from the sun. Perfect in strong backlight at sea and in the snow.


TYPES OF FOCUS SYSTEMS

Center Focus: Manual focus with central adjustment

Autofocus: Focuses (due. Lens grinding)

Individual/autofocus: Set manually on each eyepiece, then automatically focuses.


PRISM TYPES

BK7: Borosilicate standard (class B) prism material.

BK7-Select: Borosilicate prism material.

BAK-4: Barium prism material that passes light and images better than BK7. The primary difference between the two prisms is precisely the ability to guide light and image from the lens and out to the eye. BAK-4 is an excellent quality optics.
 

THE BEST CHOICE

The ideal binoculars for Marine Use will thus be a 7x50 as the relationship between magnification and light is optimal. If you have special needs, there may be other and better solutions. If you choose a telescope that magnifies more, it is difficult to keep it quiet enough that you can look sharp. If you choose a smaller lens diameter you get smaller light.
