The ArrowMaster Pro-Line Solar-Assisted Advance Warner, a versatile, low-operating-cost arrow board that provides maximum visibility while directing traffic through construction zones. The ArrowMaster Pro-Line arrow board from Work Area Protection, St. Charles, Ill., features several design changes for improved functionality. It was designed with a mast to provide lower center of gravity for additional stability during travel. The design allows the panel to travel parallel with the towing vehicle which minimizes wind resistance, fatigue and maximizes fuel economy. The center frame support is continuous from front to rear to reduce stress fractures caused by towing and rough roads. The ArrowMaster system is powered by a 210-amp marine, deep-cycle battery storage bank that charges by a top-mounted, shadow-free solar panel.
