Claim 11:
12. A rifle scope with spiral cam mechanism comprising:
a scope body;
a movable optical element defining an optical axis connected to the scope body;
a turret having a screw operably connected to the movable optical element for adjusting the optical axis in response to rotation of the screw;
an outer knob operably connected to a first set of teeth and to the turret such that the outer knob is movable between a locked position wherein the turret cannot be rotated and an unlocked position wherein the turret can be rotated;
the spiral cam mechanism operably connected to a second set of teeth;
the spiral cam mechanism defining a first stop surface positioned for engagement by a stop element to limit rotation of the turret, such that the position at which the stop element engages the first stop surface defines a zero position of the screw and the movable optical element;
the spiral cam mechanism defining a second stop surface positioned for engagement by the stop element to limit rotation of the turret, such that the position at which the stop element engages the second stop surface defines a maximum point of displacement of the screw and the moveable optical element;
wherein the first stop surface and second stop surface are connected by a channel wherein the channel defines a first transition and a second transition when the channel overlaps itself for the first time and second time, respectively; and
a rotation indicator coupled to the stop element that moves outward radially from the turret each time the turret is rotated,
wherein the outer knob is in a locked position when the first set of teeth are engaged with the second set of teeth and the outer knob is in an unlocked position when the first set of teeth are disengaged from the second set of teeth.
