CoursePro is a line of GPS devices that assist golfers on the golf course. They provide information on an LCD screen about downloaded golf courses that are stored in their memory. The LCDs display distances to the front, centre and back of the green for each hole along with the par. The devices calculate your shot distance and are backlit for viewing in low light. The information provided by each CoursePro GPS product gives the golfer up to the minute accurate, crucial information that will guarantee a competitive edge. CoursePro connects to a PC via a USB cable for accessing an online database of 22,000 golf courses from the Celestron CoursePro website for individual download. It is powered by a rechargeable Lithium Ion battery, with an 8 - 10 hour life per charge. CoursePro ships with a soft carrying pouch, a belt clip, Mini USB Cable and an AC wall adapter (only supplied with a USA style plug). Each CoursePro device is water resistant tested to IPX6 standards.
