Pentax MARINE 7x50 Owner's Manual

The PENTAX Marine roof prism binocular is de-
signed particularly for the boating enthusiast, but
is also ideal for any demanding environment or ap-
plication where accuracy and durability is required.
Featuring a liquid-filled compass built in to the
viewing optics, compass "swing" stops immediately
due to an advanced dampening design. Bearings are
defined in easy-to-read precise 1-degree increments,
ideal for navigation and locating objects accurately.
A range-finding scale allows the user to estimate
range based on objects of known size. The PENTAX
Marine binocular is fully waterproof, fogproof, and
shock-protected with sure-grip rubber armoring and
twist-out eyecups for easy use. PENTAX Optics are
fully multi-coated for excellent light transmission
and clarity. The PENTAX Marine binocular comes
complete with a rugged nylon case and neck strap.
Built to last, the PENTAX Marine binocular features
our lifetime Worry-Free Warranty.

How to Use:

1. Adjust interpupilary distance until a single image
circle is formed.
2. Acquire a test subject and sharply focus the left
eye using the center focusing knob.
3. Looking through the right eyepiece turn the di-
opter to sharply focus on the same subject.
Each user may have to re-adjust the binocular to suit
their particular vision correction.
Using The Compass:
The built-in precision compass features extremely
fast dampening, so there is almost no "swing" and
it is corrected for latitude (dip). The compass scale is
defined in 1 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.
