Also, you should be aware that all laser rangefinders operate by firing an invisible, tightly focused, beam of light at a given target and then measuring the time it takes for said beam of light to be reflected from the target and return to the rangefinder in order to calculate the distance to the target. Therefore, all laser rangefinders are adversely affected by hazy atmospheric conditions, glare, any objects between the rangefinder and the target and, objects that absorb the light beam instead of reflecting it. Consequently, even though rangefinders are designated as having a maximum distance at which that the particular unit will range a target, it should be noted that even though the manufacturer’s specifications may state a maximum distance of "X" number of yards for that particular unit, most will only range objects at that distance under optimal atmospheric conditions from highly reflective surfaces. However, when encountering atmospheric anomalies such as heat waves, glare, or even hazy conditions, any rangefinder’s ability to range objects over long distances will be reduced to between one half and one third of the stated maximum range! In addition, your ability to target and range objects may be further impaired by either poor optics or an overly bright reticle. Thus, some models of laser range finders feature a fixed amount of magnification but, it should be noted that while this feature does make your target appear larger in the view screen, it does not enable the rangefinder to measure accurately at longer ranges. Also, in addition to magnification, the better quality units feature multi-coated lenses that reduce glare and increase clarity which also helps you target your chosen quarry.
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.
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.
