Abstract
An aiming reticle comprising two primary characteristic feature sets consisting of a grid system and auxiliary crosshairs. The grid comprises horizontal crosshairs that are perpendicular to but do not intersect with a primary vertical crosshair. Omission of markings along the primary vertical crosshair and non-intersecting horizontal crosshairs provides improved target visibility along the vicinity of the primary vertical crosshair. The grid horizontal crosshairs are marked with intersecting major stadia lines, preferably at unit spatial intervals. The grid system further comprises self-contained crosses of predetermined size, within the space enclosed by the grid major stadia lines and grid horizontal crosshair separations to provide sub-unit reference in the vertical and horizontal reference.
