Bynolyt SeaRanger III 7x50 with compass

The SeaRanger III is an improved version of the SeaRanger II and has larger diameter eyepiece lenses allowing more light and giving a clearer, high quality image.

These images are enhanced with BaK 4 prisms and fully-coated optics.

The combination of a high quality binocular and an integrated, illuminated, liquid damped compass with distance scales makes the SeaRanger III an excellent aid to navigation.

The fully waterproof binocular is nitrogen filled and offered in a stylish design with a dark blue, non-slip rubber finish and silver eyepiece adjusters.

The SeaRanger floats when used with the bright yellow floating belt/strap which comes with the unit, making it easy to retrieve in dark seas.

A case and floating strap is included.
