Individual focus
First each eyepiece is set manually, then it automatically maintains focus.

Magnification/lens 7×50
The image is seven times larger than what the naked eye sees. 7x is the recommended magnification in marine binoculars. The second number 50 indicates how large the lens diameter is. The higher the number, the better the light incidence. This is an advantage in poor lighting conditions. For marine use, a 50 mm lens is recommended.

BaK-4 prism
Prism material barium. Is excellent at transporting light and image from the lens, through the prisms to the eyepiece and out to the eye. The BK-4 is an excellent quality optic.

Viewing angle: 7.0
The viewing angle in degrees indicates the width of the image that can be seen at a distance of 1000 meters. A viewing angle of 7.0º gives a width of 132 m at a distance of 1000 meters.

95% light transmission.
