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.
