A complete guide to selecting a Rangefinder

A Rangefinder is an optical or laser device used to measure distance.
Optical range finders work by comparing the height of an object to a scale. Laser range finders work by bouncing a laser beam of an object and determining how long it takes to return and therefore distance.
To select a rangefinder you first need to determine the size, maximum distance and type of object that is to be used to determine distance. Small non-reflective objects at long distances need very high quality rangefinders. Large shiny objects can be detected with cheaper rangefinders.
