Simply attach Great Recovery Markers to the end of your club grips. Then, put your clubs in your golf bag along with your Great Recovery Control Shaft. Turn it on and the computer in the Control Shaft quickly takes inventory of each of your Great Recovery Markers. The green light says you're good to go! When you take the clubs out of your golf bag, the indicator light turns to red. If all of the clubs are not returned, an audible warning is given.
