Abstract

A reticle comprises a horizontal section having horizontal section horizontal lines broken by horizontal section gaps between the horizontal section horizontal lines. A vertical section has vertical section vertical lines broken by vertical section gaps between the vertical section vertical lines. The horizontal section intersects the vertical section at a midpoint. A wide measurement ranging system includes range indicators including a highest range indicator, a plurality of intermediate range indicators, and a lowest range indicator. A height measurement ranging system has range indicators which include height measurement horizontal lines and which include a height measurement lowest range indicator closest to the vertical section, height measurement intermediate range indicators, and a height measurement highest range indicator.

Claims

1. A reticle comprising:

a. a horizontal section having horizontal section horizontal lines broken by horizontal section gaps between the horizontal section horizontal lines, wherein the horizontal section has horizontal section vertical lines;

b. a vertical section having vertical section vertical lines broken by vertical section gaps between the vertical section vertical lines, wherein the horizontal section intersects the vertical section at a midpoint, wherein the vertical section has vertical section horizontal lines;

c. a wide measurement ranging system, wherein the wide measurement ranging system includes range indicators including a highest range indicator, the plurality of intermediate range indicators, and a lowest range indicator, wherein the range indicators are correlated to the width of the vertical section horizontal lines; and

d. a height measurement ranging system including range indicators which include height measurement horizontal lines and which include a height measurement lowest range indicator closest to the vertical section, a plurality of height measurement intermediate range indicators, and a height measurement highest range indicator.

2. The reticle of claim 1, further comprising a ring bounding the reticle.

3. The reticle of claim 1, wherein the vertical section gaps have a thickness of approximately a thickness of vertical section vertical lines and the horizontal section gaps have a thickness of approximately a thickness of horizontal section horizontal lines.

4. The reticle of claim 1, wherein at least some of the vertical section gaps denote half of 0.1 mil and wherein at least some of the horizontal section gaps denote half of 0.1 mil.

5. The reticle of claim 1, wherein the height measurement ranging system is located in the top right quadrant of the reticle.

6. The reticle of claim 1, wherein the height measurement ranging system includes at least fourteen height measurement horizontal lines.

7. The reticle of claim 1, wherein the height measurement ranging system includes at height measurement horizontal lines, at least some of which have a height measurement vertical line extending downward from a midpoint of a height measurement horizontal line.

8. The reticle of claim 1, wherein the a wide measurement ranging system has wide measurement range indicators set for 0.5 meters in width.

9. The reticle of claim 1, wherein the a height measurement ranging system has height measurement range indicators set for 1.7 meters in height.

10. The reticle of claim 1, further comprising a target clear spot immediately above the midpoint.

11. The reticle of claim 10, further comprising a ring bounding the reticle.

12. The reticle of claim 10, wherein the vertical section gaps have a thickness of approximately a thickness of vertical section vertical lines and the horizontal section gaps have a thickness of approximately a thickness of horizontal section horizontal lines.

13. The reticle of claim 10, wherein at least some of the vertical section gaps denote half of 0.1 mil and wherein at least some of the horizontal section gaps denote half of 0.1 mil.

14. The reticle of claim 10, wherein the height measurement ranging system is located in the top right quadrant of the reticle.

15. The reticle of claim 10, wherein the height measurement ranging system includes at least fourteen height measurement horizontal lines.

16. The reticle of claim 10, wherein the height measurement ranging system includes at height measurement horizontal lines, at least some of which have a height measurement vertical line extending downward from a midpoint of a height measurement horizontal line.

17. The reticle of claim 10, wherein the a wide measurement ranging system has wide measurement range indicators set for 0.5 meters in width.

18. The reticle of claim 10, wherein the a height measurement ranging system has height measurement range indicators set for 1.7 meters in height.
