Optics Most rangefinders will offer magnification of some sort in the form of a monocular (some are available in a binocular). The magnification typically ranges between 5 and 8 power. The quality of the optics will vary with the quality of the rangefinder, and again the more expensive models offer far superior optics clarity and magnification than do the cheap models.
Range The distances at which rangefinders can effectively calculate distances can vary from 100 meters to up to 25 kilometers, and quite possibly much further if the investment warrants it. Generally the super long distance rangefinders are built for military purposes and used by snipers and artillery units.
Dynamics Laser Rangefinders use an invisible, narrow laser that is pointed at an object to determine the distance it is from the user. The laser beam is then reflected off that object and back to the laser rangefinder instrument. The rangefinder then uses a super high speed clock to determine the amount of time it took for the laser to bounce back and then uses a mathematical equation to calculate the amount of distance between the rangefinder and the target object. The whole process is called "Time of Flight" in scientific terms.
