Welcome to a world of adventure with your new Bausch & Lomb® Discoverer® Zoom Spotting Scope. The nature student and sportsman who takes pride in optical quality can make no better choice than the Discoverer Zoom
MOUNTING
The Discoverer’s tripod mount provides a convenient means of fastening to any standard photographic tripod, car window mount or shooter’s stand. For best viewing results, mount your Discoverer on a firm support to prevent movement of the scope. Movement makes the viewed scene appear to dance or vibrate at high magnifications. Afirm mount will also help you to locate, track and keep objects in the field of view.
LENS SHIELD
Unscrew and remove the lens caps from the objective lens and eyepiece. The objective lens shield may be extended by pulling it out from the end of the scope.

FOCUSING
The Discoverer used as a spotting scope will focus from 24 feet to infinity at any power setting with rotation of the Focus Control Ring.
Make sure the Telephoto Adjustment Control is turned
The depth of field (visual distance over which the image is seen in sharp focus), and the area covered, is greater at the lower powers. However, if the instrument is initially focused at a low power you may find that additional focus adjustment is required as power is increased.
Some users may have difficulty
USE WITH EYEGLASSES
By the use of its retractable eyecup, the Discoverer affords the user the same eye relief (distance from the eye to the eyepiece at which a full field of view is seen) with or without eyeglasses. Turn the knurled eyecup clockwise for use with eyeglasses - counterclockwise for normal use. Except in cases of astigmatism, most users will choose to remove their glasses since the focus adjustment accommodates for near and far sightedness and a full sight picture is achieved without disturbing side light.
