DHC Features The PowerBug GT DHC stands for Down Hill Control. Down Hill Control allows the trolley user to automatically maintain a constant speed when walking down hill, preventing the trolley from running away when being used on a hilly golf course. In addition to the Down Hill Control, the GT DHC also features a parking brake. This allows the trolley to be safely parked on a hill or slope eliminating the risk of the trolley rolling away whilst unattended.

Battery Level Display Clock Lost Ball/Round Timer 3 Different Distance Measurements VRAP Display & Countdown VRAP - Distance Control The Variable Run And Park distance control feature provides three different pre-set distances allowing you to set the PowerBug trolley to run on its own and stop helping to save time whilst on the golf course.
