Magnetic Valve & Utility Locator for Underground Infrastructure

The ST 102 Magnetic Valve & Utility Locator is a professional magnetometer designed for accurately locating buried valves, valve boxes, curb stops, hydrants, manhole covers, and other ferromagnetic infrastructure. Built for water utilities, gas utilities, municipalities, and utility contractors, it quickly detects iron, steel, and cast-iron objects while ignoring aluminum, copper, and other non-ferrous metals.

Featuring advanced SMART+ Mode, polarity indication, audible detection, and a waterproof probe, the ST 102 simplifies locating underground utility assets—even near fences or other large metal structures. Its rugged design and up to 100 hours of battery life make it an ideal tool for daily field use in all weather conditions.
