Abstract
The invention is a highly precise sight for archery. The invention uses a C-frame that is attached to the bow by a bar. Across the open area of the C a blade is attached. The blade contains a rack and along the blade runs a gauge on the rack. For an archer to sight he moves the gauge up and down the blade which moves the sight up and down. The archer can precisely measure to one thousandths of an inch from the gauge. Thus if an archer wishes to reposition his sight to the exact location within a thousandth of an inch all that is necessary is that he write down or remember the gauge readout. In one embodiment of the invention the gauge is analog. In another embodiment of the invention the gauge is digital. The sight also has a windage adjustment that can also be adjusted down to one thousandths of an inch. To get the accuracy down to one thousandth of an inch for this elevation and still manufacture the sight inexpensively, applicant used the parts from mass produced calipers. He takes a regular caliper with the jaws removed using only the blade and the gauge and places it in a c-shaped frame that attaches to the bow, and mounts the scope housing to the gauge of the caliper.
