There are so many different golf range finders on the market today, it is important to understand the differences between the various technologies that exist and why one might be better than another. There is some discussion amongst golfers about how appropriate the use of such devices is. Is it against the rules? Why or why not? Let's take a closer look at some of these issues.
First, what are the competitive technologies for golf range finders? Most fall into one of two categories: GPS units, or laser range finders.
Golf GPS units use global positioning system technology to help golfers identify yardage distances. GPS uses satellites to provide positioning data. The satellite sends a signal to Earth and tracks the time between transmission and reception of the signal. To get accurate data, a process called trilateration is used. Between several satellites working to provide signal data and with geometric trilateration, accurate positioning data can be sent to a receiver. IN this case the golf GPS receiver.
What makes this so nice is that you can get accurate distances to the pin, but also combine a great user experience. The golf GPS units are universally more fun to use than a laser range finder. The GPS units come with large color screens (depending on model). You can even upload course maps, get green elevations and see how other holes are laid out nearby, Golf GPS units are really fun to use.
Golf laser range finders are a little different. These devices fire a laser beam, or series of laser beams, at a stationary object – a pin in this case. The laser reflections provide the device with an accurate distance. These measurements tend to be very accurate.
The laser range finder is used by looking through a scope. While looking through the viewfinder, you line the cross hairs up on your target, be it a pin, tree, or other hazard. Once the target is lined up, you start the device. The yardage is displayed inside the view finder to the user.
The nice part about the laser range finders are that they are easy to use, easy to set up and can be very small. For example, the Bushnell Medalist with Pinseeker comes in at just over four ounces! Ease of use and accuracy make them quite a nice option.
For all out fun and a lot of interesting data, the golf GPS unit is the way to go. With all sorts of interactive products like the Yardage Pro Golf GPS from Bushnell, you'll have a great time. For pure accuracy and ease of use, you can not go wrong with a laser rangefinder.
