I sell professional-grade metal detection and utility locating equipment, and I know this gear inside and out. Here I cover detailed product specs and reviews for valve locators, pipe and cable locators, and magnetic locators from brands like Fisher, Schonstedt, and Metrotech. Whether you need to locate buried valves up to 42 inches deep, trace underground pipes when the starting point is unknown, or detect ferrous metals and energized power lines, I break down exactly what each tool does. My focus is practical utility applications for damage prevention and underground infrastructure management.
