Optical Rangefinders Rangefinders come in many different shapes and sizes. Many of them also have a particular use that they are best suited for. Some rangefinders are fully automated, but many of these are used either by the military or in very specific jobs such as land surveying. For most of us, however, the use of optical rangefinders is what we really need. They find their way into our little bag of tricks whenever we are in the field hunting or on the golf course. The reason that they are known as optical rangefinders is really rather simple, you look through them and see what you are measuring to and they give you the distance. Optical rangefinders come in many different shapes and sizes as well as uses for various sports afield. For example, optical rangefinders that are specifically made for golfers will vary in their options with those that are made for people that hunt. In the same way, optical rangefinders might double as binoculars and this is especially handy for people that are hunters because it helps them to combine a couple of tools and to save pack space. It is really rather interesting how optical rangefinders work. They send out a beam of light which bounces off the object in question and comes back to the rangefinder. Since light has a specific speed at which it travels, the rangefinder is able to calculate the distance simply by the amount of time that the light talk to return. Even though this is great technology, it is not without limits. Things such as atmospheric conditions, weather and the reflectivity of the object will affect the accuracy of the rangefinder. Many of them, however, offer one-yard accuracy which is much more than most sports enthusiasts need. So if you enjoy being out in the field, it doesn't matter if you hunt, fish or golf, having an optical rangefinder with you will benefit you in some way or another. Not only will it help you to be more accurate with your shot, it will also tell you how far away something is at a moments notice.
