There are a number of things that can benefit from GPS range findersor range finders in general. This ranges from golf to hunting to even surveying or photo taking. What this device does is measure the distance between two points. There are three different types of range finders but not all of them are good for every application. Optical range finders typically do not work for golf or bow hunting, for example. Reflective (using laser or sonics) and GPS range finders have enough accuracy to work well for bow hunters and for golfers. Reflection usually is good for up to 1500 yards while GPS is good for calibrating where there are fixed items and are as accurate down to the inch.
Since both basic and GPS systems work for golfing, what you chose should come down to what you can afford and what is allowed on your most commonly played course. If you are a statistics nut, you might want a special golfing GPS range finder. These units can keep your stats, score, and multiple distances to various hazards all at the same time. What makes this more attractive than a normal range finder is that a GPS unit can also adjust for slope, something the laser or sonic will not do. You may also find some that see the hole pin to provide a more accurate distance to your current location. Be aware that not all range finders are allowed during tournament play.
GPS Range Finders can vary widely in price. They also vary widely in coverage and cost of use. Before investing on a GPS range finder, you should check not only the usage details and any other long-term plan costs, but also if they are allowed on the course you play most often. This is not to say that there is no benefit to having one. The knowledge that comes with knowing the distance of each shot can help you lower your handicap by giving you the information you need to select the correct club every time. This will help you hit the green where you want to hit it more often.
The suggested course to follow for finding the perfect GPS system is to do your research. The Internet has a lot of great resources, both sellers and reviewers, that can help you narrow down your choices. Knowing your budget, the courses you want to play, and the opinion of other GPS users can help you chose the perfect unit for your needs. Another good source of information is your local golf club. You can ask them if they are using a system to keep track of distances and if so, which one. If they are not, you can find out why. If you happen to have a course that is too new or small to have GPS data for a GPS unit then a laser unit is cheaper. Using one means keeping track of your own stats, something a good GPS unit can do for you.
