The versatile magnification of the Viper spotting scope allows you to view a wide field
of view at lower power, then zoom in on distant details.
Adjust the magnification
Change the magnification of your spotting scope by
simply turning the magnification adjustment ring.
• Increase the magnification by turning
the adjustment ring in a counter-clockwise
direction.
• Decrease the magnification by turning
the adjustment ring in a clockwise direction.
Caution: Never look directly into the sun (or any other intense light) with your Viper spotting
scope. This could cause damage to the retina and cornea of your eyes to the point of causing
blindness.
Fine focus of the Viper spotting scope
After setting the magnification, you can adjust the fine focus. This does more than
allow you to see critical details, it also ensures fatigue-free viewing. When you change
the magnification, some refocusing is usually required.
Handle the coarse and fine adjustments with just the tip of a finger:
1. Slowly turn the coarse focus dial
until the subject is nearly in focus.
2. Turn the fine focus dial to pick out
the finest details.
