7 X 50 Marine Boat Yacht Equipment Binoculars BK7 Porro Prism WS Series

7 x 50 Boat Binoculars BK7 Porro Prism WS Series Marine Navigation Equipment

Brief Introduction:

Binoculars are described using two numbers, such as 7 x 50 or 8 x 25. The first number identifies the

magnification or power. The second is the diameter of the objective lens (the lens at the front) in

millimeters. Magnification power describes how much closer objects appear when you view them. In a

7 x 50 binocular, the image is magnified seven times. Increased magnification reduces the brightness

of the image, so as magnification increases, binoculars require increasingly larger objective lenses to

maintain brightness. The larger their size, the more light they can gather.
