How Rangefinders Work There are many different brands and styles of laser rangefinders from which you can select. They’re manufactured by Opti-Logic, LaserTechnology, Newcon Optik, Nikon and Bushnell, just to name a few. As there are naturally many choices, you first need to know how an electronic rangefinder works to help you select the best one for your needs.
Archery Rangefinders: These rangefinders are generally designed for ranging animals at close distances as shots over 100 yards are not needed by bow hunters. Often times these units will have a lower magnification to help the user range the animal faster at close range. Many archery hunters prefer to have some sort of angle compensation feature on their rangefinders, especially those that hunt from tree stands as these models will also factor in the angle of the shot, which can affect where the archer aims. Optics maker Leupold has recently introduced a unique archery rangefinder that mounts directly to your bow and can be utilized at full draw; however; this device is not legal for hunting purpose in all states.
As you can guess, the rangefinder’s laser helps pinpoint the distance between you and an object. To delve deeper, laser rangefinders typically use three different lenses: the viewfinder, the main camera lens and the reflector lens. When using the rangefinder, you look through the viewfinder and the main lens is responsible for gathering light to help the device focus. The third lens overlays the target on the viewfinder so you can pinpoint your target. When you press the button on the electronic rangefinder, a laser shoots out from the rangefinder and towards your target. The laser bounces off your target and gets sent back to the rangefinder, which immediately calculates the distance between you and it.
