Whether you need a robust pin finder or a precise magnetic locator, you can count on Bench Mark for quality and dependability.
In surveying, magnetic locators are used to locate iron and steel objects such as property pins, manhole covers, valve boxes, and survey monuments. Their ability to distinguish between ferrous and non-ferrous materials ensures quick and accurate results in the field.
Surveyors commonly use magnetic locators to find buried survey markers or property pins made of iron or steel. Models like the ML-1 and ML-3 provide strong signal feedback, helping professionals pinpoint markers quickly, even in challenging terrain.
Magnetic locators are specialized instruments that detect only ferrous metals such as iron and steel, which makes them perfect for finding survey pins, corner markers, and rebar. Traditional metal detectors, on the other hand, detect all metal types – including aluminum and copper – making them better suited for general treasure or utility searches, not precise surveying.
Our magnetic locators are designed to detect ferrous metal objects quickly and accurately, making them ideal for locating property pins, live wires, survey markers, and other buried objects.
High-quality magnetic locators, such as the SubSurface ML-1 and ML-3, can detect buried ferrous metal objects at depths of up to 10 feet. This range provides excellent performance for most surveying, utility, and property pin-locating applications.
For accuracy and depth, the SubSurface ML-3S Magnetic Locator is one of the best detectors for survey pins. It’s engineered to locate iron and steel objects with precision while filtering out non-ferrous metals, making it ideal for survey and construction applications.
Each magnetic locator from SubSurface Instruments comes with a 7-year manufacturer’s warranty. Built with durable aluminum and ABS plastic housings, these instruments are engineered for long-term reliability in demanding field conditions.
