SkyCaddie Mapping Methodology

SkyGolf Mapping Methodology
Did you know that other GPS devices can be wrong up to 50% of the time?

The reason is twofold: The first problem with other golf GPS devices is the components used in their products and the second is how they create their maps.

The antenna and GPS engine can produce poor results when tested for golf application. The error in GPS is circular. As the satellite signals are received, the signals can register as accurate up to 50% of the time (50% CEP) and the other 50% they can be up to 0-15 yards off. When the error is in line with your target, the error is revealed in distance that is either too short or too long. When the error is perpendicular to your target, the error can be disguised. The problem with the poor quality components of these other GPS devices is the inconsistency of their accuracy.

The second part of the problem is their maps, which are often second or third generation maps. No other company in golf GPS walks every course with high precision, survey grade equipment that measures to under a yard. Without verifying the exact location of tee boxes, bunkers, hazards, greens, etc., the map error compounds the error that already exists in the hardware.


SkyCaddie takes no shortcuts when it comes to your game. Only SkyCaddie walks every course with professional high precision grade survey equipment to create original course maps with precision of less than one yard. SkyCaddie provides the most complete, most reliable and most accurate course maps in the game so you can trust your SkyCaddie just like Tour Players thrust their caddie.
