The Bridgeboard is designed for making discharge measurements and obtaining water quality samples from bridges. It is a free-standing support, accommodating Type A-55, A-Pack, Type A or B-56 sounding reels. It comes with an adjustable foot rest which makes it easily adaptable to bridge railings of different heights and walkways of various widths. The suspension cable is stretched out over the sheave at the end of the 4 foot long boom and the current meter or sampler is then suspended from the cable and lowered into the water. A roller kit and boat mount are available for the bridgeboard. The recommended maximum sounding weight to be used with the bridge board is 50 pounds (23 kg).
