First Claim
Patent Images
1. A sighting device with a turret comprising:
- a movable optical element;
a screw engaged with the movable optical element such that rotation of the screw causes movement of the movable optical element;
an outer knob operably connected to the screw such that rotation of the outer knob causes rotation of the screw; and
a top knob movable between a raised position and a lower position and engaged with the movable optical element such that rotation of the top knob causes rotation of the screw; and
further wherein the outer knob has a first outer perimeter and the top knob has a second outer perimeter, wherein the outer perimeter of the outer knob travels a greater distance than the outer perimeter of the top knob when moving the screw the same amount of degrees.

Abstract
An optic device turret for adjusting the optical element of the optic device with at least two knobs that are each movable between a first position wherein the knob is not rotatable and a second position wherein the knob can be rotated. The access to and rotation of both knobs can be accomplished without the use of tools. The rotation of each knob adjusts the optical element. A spiral cam mechanism is engaged with the turret to define a maximum and minimum adjustment of the optical element. A rotation indicator displays the amount a knob has been rotated.
