ZEROING: Select the reticle you desire by turning the reticle selector knob and set the intensity at the best position for you. With the E/D sight mounted,rest gun on a solid support and aim at a target 50 to 100 yards away.Test shots should be done in the same conditions to achieve maximum accuracy for adjustment,for which the use of firm rest for firing and same type cartridge is recommendable.Each click adjustment moves the point of impact by 1 MOA(approximately 1" at 100vbs,1/2" at 50 yds). Reflex sights are popular thanks to the intuitive, non-magnified method they employ to help you aim your telescope accurately. Depending on your chosen LED color, a small LED emits a red or green aiming pattern onto a viewing window which you peer through to aim the telescope after a simple alignment procedure.Once the pattern is lined up with your intended target object, you're all set to view it through the telescope. The Finder Deluxe is a non-magnifying reflex sight that makes aiming your telescope easier and more accurate than ever - day or night! Finder projects a small red or green LED reticle pattern onto a viewing window so you can easily aim your telescope at night or during the day. Horizontal and vertical fine-adjustment set-screws allow precise alignment of the reflex sight with the telescope. Includes dovetail finder bracket that fits most telescopes. Requires CR-2032 lithium button-cell battery (Not Include). Finder Deluxe features a large viewing window, four different aiming reticle patterns to choose from, and five brightness levels of red or green light. The power of the finder will be turned off when you turn the knob to "R" or "G".
