There are two main ways one can have a Golf GPS system. One is for the player to have their own inividual Golf GPS unit. The other is for the course to provide the system.
From the golfer's point of view, a GPS system that the course owns can be beneficial in many ways. An integrated system can allow players to order food and drinks, allow two-way communications, and give weather alerts. The system can even be a revenue generator by being an advertising medium.
These units are most often cart-mounted, meaning that the golfer does not have to invest in there own receiver or carry a device. However, these units do not allow accurate measurements due to the fact that they are usually not removable, causing an error in distance between the cart and the golfer's position.
You may have had a playing partner pull one of these easy navigation self contained Golf GPS Units out and tell you to forget about looking for the sprinkler heads because you're exactly 143 yards from the flag. Impressive, I'd say!
The self contained easy navigation GPS unit for Golf combines the GPS receiver, interface and necessary software into a small handheld package.
The actual golf course parameters required to power one of these units are usually available in an add-on-package or individually by subscription.
Some units are stand-alone, meaning their only function is a Golf GPS. Others can be attached to a PDA type unit with various software. Not only can a Golf GPS Unit tell you the distance to the pin, it also can track how far you hit each and every shot , as well as score keeping. Some include pro tips.
