The nature student and sportsman who takes pride in optical quality can make no better choice than the Discoverer Zoom 15x-60x Spotting Scope. The Discoverer is one of the optically finest, most versatile 60mm spotting scopes in the world. With the D i s c o v e r e r, the user can scan an area with a wide, bright field of view at 15 power and instantly zoom in for breathtaking 60 power close-up. The Zoom Power Control Ring smoothly increases or decreases the magnification as desired. T h e exterior body contains a unique rubberized surface providing d u r a b i l i t y, noise reduction and a non-reflective surface. T h e following directions should be followed closely to assure sharp clear observations. Power Exit PupilFOV At 1000 yds M O U N T I N G 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. Power: 48 oz. Weight: 17.5” Length: 15mm Eye Relief: 60mm Objective Lens: 15x to 60x F O C U S I N G 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 counter-clockwise as far as it will go. 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 re-focusing after zooming rapidly to a higher power, this can be caused by the eye’s inability to adjust quickly enough to the new magnification. It will help to look away momentarily, then resume focusing. USE WITH EYEGLASSES By the use of its retractable eyecup, the Discoverer aff o r d s 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. Continued on page 2 CHANGING POWER To change magnification, rotate the Zoom Power Change Ring to the desired power as indicated by the white engraved scale. As you zoom from low power to high power under low light conditions, you may notice a decrease in image brightness. This is normal. All magnifying optical instruments show a decrease in image brightness as magnification is increased. 3 . After setting up, locate the subject through the camera’s viewfinder in the usual way with the spotting scope at it’s lowest magnification. This gives the widest field of view. Once located, you can frame the picture as desired with the Zoom Power Change Ring in the same manner as when using it as a spotting scope, then use the focusing system of the spotting scope to bring the subject into sharp focus. Minimum focus distance as a telephoto lens is 80 feet.

It then becomes an integral part of the camera’s optical system and functions as an extra powerful zoom lens. The two accessories needed for this are; a #22-3030 Telephoto Camera Mount and a Camera Body Adapter that matches your particular camera (see listings under accessories at the end of these instructions). TO A S S E M B L E 1 . Turn the spotting scope’s Telephoto Adjustment Control Ring clockwise all the way until it stops, then screw the Telephoto Camera Mount over the eyepiece. 2 . Screw the Camera Body Adapter to the other end of the Telephoto Camera Mount. 3 . Remove the standard lens from the camera and attach the body to the Camera Body A d a p t e r. TO USE 1 . Films with the highest ISO ratings are recommended. The faster the shutter speed, the sharper your picture. 2 . Mount the spotting scope on a sturdy tripod or shooter’s stand. A car window mount is also available but it is recommended that the camera not be operated while the car motor is running since the sli...
