Answer: A detectable duct rodder is a specialized fiberglass duct rod with a copper wire integrated into its core. This allows the rodder to be traced from above ground using a signal generator and cable locator, making it an indispensable tool for underground utility projects. Its non-conductive nature ensures safety, while the traceable core provides the precise location and depth of buried ducts, saving significant time and cost by eliminating the need for extensive excavation. Ningbo Changshi offers a range of traceable duct rodders designed for efficiency and safety.
