A laser rangefinder is a device which uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used.
There are certain criteria you need to look into when choosing a laser range finder, such as usage purpose, for hunting or golf, magnification and distance, size and weight and also features such as scan mode or other modes available etc. Bells and whistles and various modes add to the cost of a rangefinder and are rarely used. Get a high quality rangefinder in the appropriate main mode for your most-used application with the most distance available. This will ensure that small targets like deer and flags can be ranged at 1/3 or more or the rangefinder's maximum capable distance. Buy a good one once and it should last you a lifetime.
