This measurement is at times made more difficult by many variables. Rivers, hills, trees, rocks, and other land marks often interfere with your depth sensing, even short distances can be difficult to gauge. The correct shot distance can be ascertained by the use of a rangefinders, there by helping the hunter to measure out his shot.
Today we will talk about just how a laser rangefinder functions. The distance to an objective is calculated by a rangefinder by the rebounding of a laser light beam off the object to be ranged. The time it takes for the laser light beam to reach the target and return is measured by a high speed digital clock. This time that commonly takes less than one second, is then computed by the rangefinder and displayed as a distance on the rangefinders build in screen.
History Rangefinders have actually been around for quite a while; clear back into the 19th century. Laser rangefinders in particular, being not nearly as old, have only become popular to the average person in the last 20 years or so. They have been used by commercial and military operations for some time now, but these models were typically too big and heavy, and way too much for the average person to use on a day to day basis, not to mention they are much too expensive for the average person to afford.
