The SubSurface ML-3 and ML-3L Magnetic Locators are professional-grade instruments designed to quickly and accurately locate buried ferrous objects, including property pins, valve boxes, manhole covers, survey monuments, rebar, and utility markers. Built with a rugged aircraft-grade aluminum housing and an IP68 waterproof rating, both models are made to withstand demanding jobsite conditions. Features like digital tuning, auto-zero technology, and adjustable sensitivity provide reliable performance for surveyors, utility contractors, municipalities, and excavation crews. The only difference between the two models is the overall length—the ML-3 offers a compact 40-inch design, while the ML-3L features a longer 55-inch shaft that provides greater reach and helps reduce bending and fatigue during extended use. Both models deliver the same dependable locating performance and are built to handle everyday field work with confidence.
