Ranging 1000 by Coleman Range Finder - Vintage in Original Box

A cool old fashioned way of accurately judging distance.
Cool in that it is purely mechanical requiring no batteries only good vision.
It is difficult to see objects out to the advertised 1000 yards.
Best distance is to about 400 yards. The rangematic 1000 works as all optical
rangefinders do in that you look through one eye piece and you see out two.
The farther apart the two lenses are the greater the distance you can accurately
judge. The two images you see are through different color filters and because there
is space between the two lenses and you see it through one the image appears
blurry, you then rotate a wheel changing the angle of you of the mirror inside until the
two images are perfectly aligned.
The angle of the mirror is than used mathematically to determine at what distance
the two images would line up telling you how far away the object you are ranging is.
Thankfully all the figuring has all ready been done and you just look at the wheel to
tell you the distance. The included directions are quite helpful in explaining how to
operate it.
