1. A rifle scope comprising:
- a body;
a plurality of optical elements in the body;
an adjustment knob rotatably connected to the body;
the adjustment knob being connected to at least one of the optical elements, such that an image shift is generated in proportionate response to rotation of the adjustment knob;
a detent mechanism operationally engaged to the adjustment knob;
the detent mechanism having a plurality of detent positions;
each detent position having a corresponding detent force by which the detent mechanism resists movement;
the detent force for a first plurality of the detent positions having a first value;
the detent force for a second plurality of the detent positions having a second value greater than the first value;
wherein the detent mechanism includes a first surface portion having a first plurality of similar evenly spaced ridges for engagement by a first spring biased contact element; and
wherein the detent mechanism includes a second surface portion having a second plurality of ridges for engagement by a second spring biased contact element, and wherein there are fewer second elements than first elements.

Abstract
A rifle scope has a body with a number of optical elements. An adjustment knob is rotated we connected to the body and interacts with at least one of the optical elements to provide an image shift in response to rotation of the knob. A detent mechanism interacts with the knob, and has a number of detent positions. Many of the detent positions have a first detent force, and a selected subset the detent positions have a greater second force. The selected subset of detent positions may correspond to selected major distance intervals.
