Variously described as the most tranquil pastime possible as well as the most dependable means upon which a person can hope to successfully ingratiate themselves with their superiors and network to aid in job promotions; golf can be an exceptionally challenging game indeed. For those of us whose golfing skills leave a lot to be desired, it can be downright infuriating.
Are you frustrated and envious of your golfing rival and their seemingly uncanny ability to hit the ball with near perfect precision? Are you desperate to finally put them in their place, and rob them of their smug sense of superiority over you? Never fear: golf are range finders here… to aid your game and improve your score.
In essence, and as the name would perhaps indicate, a GPS range finder relies upon satellite driven mapping technology in order to provide the golfer with the coordinates and the relative distance between any two points.
Some consumers, particularly, novice golfers; have expressed their concern over the seemingly steep price tag associated with the Bushnell, Leupold, Callaway LR550 golf rangefinders.

Most modern receivers contain built in electronic map. For example, the Garmin GPS 3 Plus includes North America, every major roadway and waterway in Canada, the United States and Mexico. Receivers have only so much memory preventing the maps from being very detailed, although they do include an impressive amount of data.
Do not expect the base map to include the nameless dirt road traveled down to your favorite camping spot. Fortunately manufactures provide additional memory allowing the user to up-load greater detailed mapping information.
Detailed topographical maps are also available on CD ROM that include any part of the world. Greater detail such as elevation lines suck up the available memory, making it necessary to be selective on how much additional mapping can be added. Some units also accept memory cards providing great detail of larger cities or ocean ports.
A electronic map is viewed in greater or less detail by using a Zoom feature. When initially viewing the Map Page, the current location arrow icon will be in the center of the screen.
The screen will also have a distance indicator to determine the scale of the current map. The initial map will be larger making it easier to find a desired area. Once the area is located, zooming in will increase the map’s detail. Roads, waterways and their names will appear as the map is zoomed into a specific area. Most receivers have a wide zoom range from 2000 miles to 500 feet.
Using a rocker keypad, a cursor in the shape of a small arrow will move about the map. A dialog box will display changing latitude/longitude coordinates and the distance from the current location. This is useful for finding approximate distances to nearby locations.
For example, from our location in Springfield, Oregon, scrolling the cursor north up I-5, the arrow is placed on downtown Portland, Oregon. It gives a distance of 103.5 miles. Distance is “as the crow flies”, which appears accurate in this example because the driving distance is approximately 110 miles. It also shows that its direction is 7° north, and provides Portland’s latitude/longitude coordinates. We now have the option to save this destination as a Waypoint.
