The water-resistant design of this GPS unit helps to make it durable. The included plaster holster and belt clip make it easy to carry the Tour around (it weighs only 4.23 ounces). This model differs from the lower cost Pro model in that it has a color screen (as opposed to the Pro's simple LED backlit screen) However, this model lacks the higher cost World Platinum model's 40,000 course capacity, pre-loaded courses from around the world, high-resolution full function touchscreen, four player scoretracking module (instead of the Tour's single player scoretracking module), full statistical analysis module, zoom in/zoom out functions, ability to measure to and from any point on the hole, shock-resistant case design, fifty channel sattelite reception (the Tour only has twelve channels), distance measuring module, pin placement/movement functionalilty, and swivel holster. The GolfBuddy Tour golf GPS unit comes with a wall charger.
