Bushnell MARINE 13-7500 Manuel D'instructions page 2

The BUSHNELL MARINE is the perfect binocular for sailors and outdoorsmen. Features a
liquid-filled compass built into the viewing optics. Compass swing stops immediately due to
advanced damping design. Compass bearings are called out in easy-to-read precise 1° increments.
Ideal for shipboard navigation work or locating objects accurately. A range-finding scale allows
the viewer to estimate the range of objects to 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. Optics feature fully multi-
coated lenses for excellent light transmission. The BUSHNELL MARINE comes complete
with rugged nylon case and neck strap. Built to last, with a lifetime limited warranty.

HOW TO USE
First, adjust the width (interpupillary distance) of your binoculars 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.
USING THE COMPASS
The compass is a precision unit. It has extremely fast damping so
that there is almost no 'swing' and is corrected for dip (Latitude).
The compass scale is in one degree increments and is aligned with
the vertical range finding scale. When using the compass, always
keep in mind the local variation between magnetic and true north.
HOW TO USE THE RETICLE
The vertical scale (reticle) visible through the left half of the binocular, above the compass
display, allows you to calculate distance to an object if you know its height, or to calculate the
height of an object if you know its distance from you.
