Range finders were created to help golfers know how far they are from their target when playing on large courses. This device can measure the distance quickly and accurately, making it a perfect tool for a golfer’s activities. There are three types of range finders available today: the GPS range finders, the laser range finders, and the optical range finders.
The GPS range finder gets feeds from the four satellites that are orbiting the Earth to know the current location of the user on the golf course. The laser range finder, on the other hand, measures the distance based on the length of time that the beam bounces back from the target and return to the user. These two range finders need the power to function properly and provide the results expected from them.
Of all the three types of range finders, the optical range finder is the most cost effective. Since it does not need the power to do a calculation of yardages, it is more reliable for the golfer to use. He can take it to any golf course in the world without fear that it will run out of power in the middle of the game. There is no need to download courses, get subscriptions, or change batteries. It is also more affordable than GPS and laser range finders as well.
How Optical Range Finder Work
The optical range finder is equipped with built-in scales that can measure any distances. It measures the height of the pin in the eyepiece and converts the reading with the help of pre-loaded conversion charts. The optical range finder uses a form of triangulation called the principle of parallax. The images gathered by the two lenses located at the opposite ends of the device that focuses on the target object are superimposed to each other with the use of a focusing knob. The focusing knob is adjusted together with the scale that translates the reading into yardage. However, one should have a steady hand to focus the optical range finder to the pin in order to get the exact data.
Advantages of the Optical Range Finder
Optical range finders are cheaper than GPS range finders and laser range finders. It is easy to carry around because it is lightweight and there is no need to lug around extra weight on the golf course. It is a more competitive option because it uses built-in scales for measurement, not downloadable maps that sometimes can be accessed with a fee or paid subscription. Unlike other types of range finders, the optical range finder is not easily perplexed by branches, trees, snow, or rain lying on its way. Thus, you will not make extra manual computations to take out the obstacles on your path to the target.
Disadvantages of the Optical Range Finder
There are some technicalities to the use of an optical range finder. The user should also have steady hands to focus on the object properly. The pin should also be of the standard height for the device to work precisely. The accuracy is not as high as the GPS and laser range finders. It can mostly give 90% accuracy for long distances and 95% for less than 100 yards. Yet, these disadvantages will not be a hindrance to the use of the optical range finder.
The optical range finder has many things to offer to a golfer who wants to be at the top of his game. It is more affordable and reliable to use anywhere in the world. This tool will not make you pay extra for maps or courses and can be used for long term.
This type of range finder can also be used for hunting due to its size and weight as well as its accuracy. This is ideal for a person who plays golf and hunts at the same time. It should be calibrated to the height of the target, pin or animals, to ensure that it will perform effectively whether you are golfing or hunting.
