However, it is important to be aware that there are several different types of laser range finders on the market today designed for different purposes such as hunting, golfing, surveying, and forestry. Thus, as a bow hunter, you should make certain to choose a model that is specifically designed for archery. For instance, Leupold, Nikon, and Bushnell all produce archery specific models of laser rangefinders in a wide range of prices. Also, when choosing a laser rangefinder, you should be aware that they have different "priority" mode functions for different purposes. For instance, some rangefinders read the first object in their line of sight (called First Priority Mode) whereas, others ignore the first object and range past it to the object behind it (called Second Priority Mode). Therefore, rangefinders that range objects in First Priority Mode are particularly useful when you have an unobstructed view of the target but, rangefinders that operate in Second Priority Mode are of far more use when you have intervening brush and trees between you and your target. Furthermore, it should be noted that in addition to operating in either First Priority Mode or Second Priority Mode, many laser rangefinders are available with additional modes such as Automatic Range Compensation (ARC) or Horizontal Mode and San Mode. In fact, the ARC or Horizontal Mode is particularly useful when hunting in steep terrain because it automatically calculates the correct distance to a target at both inclining and declining angles and thus, it provides an accurate distance measurement even when aiming uphill or downhill. Whereas, Scan Mode, as the name implies, enables the hunter to range the distance of multiple objects by holding down the Scan button and then moving the rangefinder back and forth across the viewing area.
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.
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.
