Rangefinder If you need to know the distance you need a rangefinder. Rangefinders have been available for years and have worked in various ways. While most modern day rangefinders that are available to the public are categorized as being a laser rangefinder, they have also used sonar (sound) and radar.

The basic purpose of a rangefinder is to show you the distance from where the rangefinder is located to an object of some distance. They are used for such purposes as surveying, hunting and golfing but they also find a purpose in many other activities. The laser rangefinder works by sending out a beam of light and measuring the time it takes that light to reflect back to itself. It then can calculate from that round trip time how far away that object is. Typically, most hand held rangefinders have an effective range that varies from 400 to 1500 yards, depending on the type of rangefinder you purchase. Other factors that would affect the accuracy and range of a rangefinder are weather and atmospheric conditions as well as the reflectivity of the object being used to reflect the light. For most purposes it is fine for there to be some variation of a few feet or even several yards, but for other applications there is a need for great accuracy, as is the case of land surveying. Two of the most popular uses for rangefinders are hunting and golfing. Because each of these sports require a proper distance measurement in order to be accurate when aiming for the target, the rangefinder finds it's way into many golfer and hunters bag.
