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.
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.
Though a particular rangefinder may say it is rated to a certain distance does not mean that is what you will get out of a rangefinder. The maximum distance rangefinders will work will be dependent on the intended object’s reflectivity and the current conditions. The maximum rated distance is what most manufactures put on the box and is figured in ideal conditions on a reflective object. On deer sized animals, you will be lucky to get 75% of the maximum range and less than ideal conditions will drop the effective range even more. This discrepancy is less with the more expensive models and greater with the less expensive models.
