Binocular Levenhuk Nelson 7x50

Marine binoculars with fixed 7x magnification plus compass and built-in rangefinder. The wide field of view and 50mm high aperture lenses focus the light for observation in low light conditions.

Nelson models are the perfect choice for water sports enthusiasts and all other users who want to use binoculars in all conditions without worrying about getting them wet, dusty or fogged up. The binoculars are nitrogen-filled to eliminate fogging and condensation inside the optics.

The Porro prism system provides high light transmission and a stereoscopic, three-dimensional image. The eyepieces show a rangefinder measurement scale, which is used to calculate the height or distance to the object under observation. A built-in compass indicates the direction of the object.

The binoculars' housing is made of durable, waterproof plastic. When dropped into water, the binoculars stay afloat without risking damage to the optics. The non-slip coating increases grip stability.

The air-glass boundaries have been multi-coated with anti-reflective coatings to reduce unwanted reflections and loss of light passing through the optics. Twist-up shells make it easy to adjust the distance between the eyepiece and the eyes. Sharpness is adjusted separately in each eyepiece.

Complete with: carrying case, neck strap, lens and eyepiece covers, cleaning cloth.
