Claims38
A reticle, comprising:
- a) a simultaneously visible primary horizontal cross-hair;
- b) a simultaneously visible primary vertical cross-hair;
- c) a plurality of simultaneously visible secondary horizontal cross-hairs intersecting at predetermined distances said simultaneously visible primary vertical cross-hair wherein said primary vertical cross hair and said secondary horizontal cross-hairs are selected from the group consisting of etched cross-hairs, engraved cross-hairs, and printed cross-hairs;
- and
- d) a plurality of simultaneously visible secondary vertical cross-hairs intersecting at predetermined distances at least some of said secondary horizontal cross-hairs wherein said secondary vertical cross-hairs are selected from the group consisting of etched cross-hairs, engraved cross-hairs, and printed cross-hairs, wherein an intersection of at least one of said plurality of said simultaneously visible secondary vertical cross-hairs and at least one of said plurality of simultaneously visible secondary horizontal cross-hairs provides an aiming point.

A reticle, comprising:
- a) a simultaneously visible primary horizontal cross-hair;
- b) a simultaneously visbile primary vertical cross-hair;
- c) two upper and two lower sections defined by said primary horizontal cross-hair and said primary vertical cross-hair;
- d) a plurality of simultaneously visible secondary horizontal cross-hairs intersecting at predetermined distances said primary vertical cross-hair wherein said primary vertical cross hair and said secondary horizontal cross-hairs are selected from the group consisting of etched cross-hairs, engraved cross-hairs, and printed cross-hairs;
- e) a plurality of simultaneously visible secondary vertical cross-hairs intersecting at predetermined distances at least some of said secondary horizontal cross-hairs wherein said secondary vertical cross-hairs are selected from the group consisting of etched cross-hairs, engraved cross-hairs, and printed cross-hairs;
- and
- f) an aiming point indicated in at least one of said two lower sections.

A target acquisition device, comprising:
- a) a housing mounted in a fixed, predetermined position relative to a firearm;
- b) an objective lens mounted in one end of said housing;
- c) an ocular lens mounted in the opposite end of said housing;
- and
- d) a reticle, comprising:
- 1) a simultaneously visible primary horizontal cross-hair;
