Q: Is my course set up for GPS? A: Most definitely! The GPS Satellite system covers the entire globe; unless your course is indoors, the GPS will work. Q: What is on the flag or in the green? A: Nothing! The center of the green is simply a longitude and latitude location stored in the unit itself. The unit compares it's current position to the stored position and does the math. Q: Can I resell the units? A: Of course! We have wholesale prices for you if you would like to sell these units at your pro shop or retail outlet. Q: Can the units be customized? A: You bet! We can make a custom overlay for your course, corporation, or event. The units make great premiums for your best clients or customers. Q: Can I share with others? A: Once you have a course stored in the unit, it can be transferred to another unit using the included trasnfer cable. Q: How long does it take to charge the battery? A: The battery will have a full charge after being plugged into the charger for two hours with the unit off. Q: Can I trade courses over the Internet? A: Soon. We are developing a site that customers can use to share the courses that are programmed. We will be encouraging people to upload courses that they have programmed and rate the accuracy of the courses that they have downloaded. Q: What is the accuracy of the unit? A: The unit is accurate to + or - 3 yards.
