The ArrowMaster Pro-Line arrow board 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. The centre 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.
