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;
wherein when the top knob is in the raised position, the top knob can rotate and when the top knob is in the lower position, the top knob cannot rotate, 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.

13. A sighting device comprising:
- a sighting device body;
a movable optical element connected to the sighting device body;
a turret having a bore, an outer knob and a top knob; and
a screw engaged with the movable optical element to move the movable optical element and at least partially received in the bore such that the screw is rotated by rotating the outer knob and is rotated by rotating the top knob;
wherein the top knob is movable between a locked position in which the top knob cannot rotate and an unlocked position in which the top knob can rotate, and further wherein the turret further comprises;
a cam disc connected to the screw and defining a channel around the screw terminating at first and second ends; and
a cam pin connected to the sighting device body and at least partially engages the channel;
wherein each of the first and second ends are at different radially distances from the screw and limit rotation of the outer knob. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
