The Old Brass Rangefinder Make Your Own Mobile Private Range

Bill shows off a brass range estimator which is based upon an original made in 1869 A.D. It does NOT use telescopes, lasers, or anything that breaks or needs batteries. Instead, you hold a string in your teeth, hold the range finder level at the end of the string, and move a slider to frame a target from top to bottom in the "window." The distances on the side are yards based upon an object six feet high. The string has to be 25 inches from your teeth bitten near your k-9 tooth right side for right-handed left side for left-handed to the range estimator. Suppose there is a fixed parameter that needs to be estimated. Then an estimator is a function that maps the sample space to a set of sample estimates. A fixed value often an abbreviated notation is used in which the symbol is interpreted directly as a random value, but this can cause confusion. 1 Yard is equal to 0.9144 meter (m). Stadiametric rangefinding, or the stadia method, is a technique of measuring distances with an instrument. The term stadia comes from a Greek unit of length Stadion (equal to 600 Greek feet, pous) which was the typical length of a sports stadium of the time. Stadiametric rangefinding is used for surveying and in the telescopic sights of firearms, artillery pieces, or tank guns, as well as some binoculars and other optics. It is still widely used in long-range military sniping, but in many professional applications it is being replaced with microwave, infrared, or laser rangefinding methods. Although much easier to use, electronic rangefinders can give away the shooter's position to a well-equipped adversary, and the need for accurate range estimation existed for much longer than electronic rangefinders small and rugged enough to be suitable for military use or North American hunters.

Had one of these years ago. Lost it hunting, best tool you can ever have in "any field".

It’s impossible to guess how far that buffalo is on a screen since you have no depth perception.

[@ChacoteOutdoorRecreation]

Paul I am sorry you are right.

You should not set it at 25 inches. You should have a buddy or large 6 foot object at 100 yards and then move the range finder closer or farther from your face until it lines up. Then you mark that distance on the string. That's the distance YOU need for that device to work properly. You then set your string length to that lenght and it's tuned.

You earned a sub sir! Wish I found your channel sooner.

Dude you need peripheral vision to estimate distance

[@joshuamiller135]

Can you go as short as 20-40 yarda

[@daleythmpsn]

Where can I get one

[@ChacoteOutdoorRecreation]

Ted Cash or Jedidiah Starr

I understand why six foot is the base line but of you adjusted the length of the cord to frame a steel post at 100 yards for example would it still be accurate if you used it on a post of equal height at 600 yards? Does the object have to be 6 feet to work?

[@oldtrooper8320]

Yes it’s based on the height of a man at 100yrds… 6’ is the base line…

There is a rangefinder engraved by the manufacturer on my large knife blade (United Cutlery Bushmaster Survival Knife). Where can I learn to use it?
