BUSHNELL MARINE porro prism binoculars are designed for the boating enthusiast in particular, but
are also ideal for any demanding environment or application where rock-solid durability is required.
The new model 137507 features an illuminated digital compass built into the viewing optics, with
direction and bearing indicators tracking as you view. Bearings are called out in easy-to-read precise 1°
increments, ideal for navigation and locating objects accurately. The digital compass delivers reliable
accuracy anywhere in the world (both Northern and Southern hemispheres). A range-finding scale
allows the viewer to estimate the range to objects of a known size. The BUSHNELL MARINE is fully
waterproof/fogproof and shock protected with suregrip rubber armoring, and has roll-down eyecups for
use with sunglasses and prescription eyeglasses. The optics feature multi-coated lenses for excellent
light transmission, along with a UV reducing lens coating and internal UV filter to prevent potentially
harmful ultraviolet light (wavelengths below 400nm) from reaching your eyes. The BUSHNELL MARINE
comes complete with rugged nylon case and neck strap. Built to last, with a lifetime limited warranty.
ADJUSTING THE BINOCULARS
First, adjust the width (interpupillary distance) of your binoculars with the central hinge, so that when
you look through them, you see a single circular image. Then focus the binocular for one eye at a time
by turning the oculars (eyepieces) until you see an equally sharp image with each eye. If more than one
person will be using the binoculars, you should mark the left and right eyepieces for your own vision to
permit quick readjustment.
ABOUT THE DIGITAL COMPASS
The built-in compass is a precision unit with a digital display which
indicates bearing in degrees, corresponding to the direction the
binoculars are pointed, as well as the compass point heading. When
using the compass, always keep in mind the local variation between
magnetic and true north. To turn on the compass display, press the
