The Rod Outfit is for shallow streams, irrigation ditches, canals, water supply conduits, and sewers. This rod outfit can be used by wading, from a small boat or a low bridge. The Top Setting wading rod comes in English or Metric units and is included because of the ease and accuracy of setting the 0.2, 0.6 or 0.8 depth for flow measurement with the vernier scale on the handle of the rod. Also no exposed wires clip along the rod.
