"Alright. Now focus it using the wheel closest to you, and aim it at one of the targets," Goldy instructs.
The sight is 3-9x40 with a 6 mil-dot reticle. Goldy pauses until Makita seems ready.
"Now, the posts and little dots on the crosswire can be used to estimate the range to objects of known size, or to estimate the size of objects at known distances. For example: at this magnification, the distance between each dot is approximately one inch at one hundred yards. There are fourteen intervals there, and the targets are fourteen inches in diameter, so how far away are they?"
Goldy knows that the targets will be stretching from post to post, since she's used this set up herself on numerous occasions. She looks at Makita expectantly, waiting for her to complete the facile mental calculation.
