How Do Handheld GPS Golf Units Differ From Golf Range Finders?
In order to understand how GPS golf units and golf range finders differ, you must have a general idea what they are. Golf GPS units use the same technology as regular car GPS units to determine the distance and positions of hazards on the golf course. All the units work by receiving signals from a number of satellites in earth orbit. As long as there are 4 or more of these satellites in range (5 preferably) then a reasonably accurate position can be calculated (normally accurate to less than 5 meters). Once the position is known then the Golf GPS systems can compute the distance to the various hazards and green positions which are stored in the database for each club. A golf range finder is a device that uses a laser beam to determine the distance between two points. Distance is calculated by the amount of time it takes for the narrow beam to reach and reflect off the target in the distance and makes its way back to the rangefinder. A laser rangefinder could be described as the cross p
