Lasers can be used to determine the distance from an object, and this is the idea behind using a laser range finder. Such range finders are used in the military, forestry, sports and even as an alternative to measuring tapes.
A number of things need to be considered when you are contemplating buying a laser range finder. Besides the obvious price restraint, it is necessary to consider the magnification required, the range for which it is needed and any compensation features for accurate readings.
When you operate a laser range finder, you basically first need to pinpoint the object whose range you need to find. This can be done through magnification devices that bring the object into close view so that they are correctly targeted. Magnification of between four and eight are considered ideal for hunters, golfers and archery athletes.
Effective range can be the one in which you will get fairly accurate results. If the targets are larger, this maximum range can increase substantially. So the objects that are normally to be targeted have to be determined before you decide on effective range. Targeting an animal can be different from targeting large buildings or structures as surveyors would.
Angle compensation features come into play when the target is at a very steep angle from the viewing position. Laser Range Finders, under normal circumstances, such angle compensation may not be necessary for normal use.
