The high-visibility Hydra-Finder with Spring allows for quick location, even when hydrants are buried in snow or covered with seasonal vegetation overgrowth. It requires no maintenance and can be left up all year round. The resilient 3/8" diameter, white laminar matrix fiberglass Hydra-Finder shaft, which is corrosion free and UV resistant, is attached to a heavy-duty MIL SPEC zinc plated carbon steel spring mount that allows for 360 degree flexibility. The Hydra-Finder is adaptable to most standard fire hydrants with an easy to install 5/8" diameter bolt and steel "flat" or "L-shaped" mounting bracket.
