APEX GEAR proudly continues to advance the most powerful and versatile single-pin sights on the market - still without a physical pin to crowd the view. COVERT PRO maintains all the advantages of a long-range sliding sight, but with unique PWRa DOT LED technology. Tactile push-button brightness controls simplify use in the field, and a gear-drive elevation dial provides smooth and precise adjustment. COVERT PRO is available with a standard green LED dot, or a DOUBLEa DOT green and red aperture. The red LED acts as a secondary pin when the green LED is set to 20 yards, or provides a point of aim for extreme distances beyond the range of the yardage tape.
