1. An optic comprising:
a tubular body having an internal movable optical adjustor adapted to shift an image generated by the optic;
a knob connected to the tubular body for rotation about a knob axis and operably connected to the optical adjustor to position the optical adjustor based on a rotational position of the knob;
an indicator skirt operably engaged to the tubular body, non-rotating with respect to the tubular body, and threadedly engaged to the knob;
the indicator skirt being operable to move axially with respect to the knob such that the axial position of the indicator skirt is based on the rotational position of the knob;
an aperture defined by one of the indicator skirt and the knob; and
a locking device to mate with the aperture, wherein the locking device is defined by, or coupled to, the other of the indicator skirt and the knob;
wherein the locking device is engaged with the aperture during one or more initial revolutions of a plurality of revolutions of the knob, and one of the locking device and the aperture is arranged to make radial or axial movement with respect to the other of the locking device and the aperture in response to a threshold rotation of the knob, to disengage the locking device from the aperture for one or more subsequent revolutions of the plurality of revolutions.
