The SmartTRAK SitePro ST102 Magnetic Locator is the smart choice for locating ferrous metal objects by sensing the difference between two fluxgate sensors that are arranged in a manner to balance out the Earth's magnetic field. The output of the sensors are presented both as a visual and audio indication of magnetic field strength. The Smart Trak Magnetic Locator features one-handed operation with pinpoint accuracy and a large visual display. It locates ferrous metals underground: buried manholes, steelcovers, septic system handles, corner survey markers, cast iron pipes, iron valves.  

0-99 numeric indicator with polarity indicator and signal strength graph bar.

The SmartTRAK SitePro ST102 offers the Smart-Search Technology with North/South polarity that provides pinpoint accuracy around fences or other large metal objects. 

Smart-TRAK™ is the smart choice for locating manholes, steel covers, septic systems, corner survey markers, cast iron pipes, iron valves, re-bar, and other ferrous metals underground.

When ferrous objects are oriented vertically to the earth's surface, a magnetisation is induced into the object by the earth' magnetic field creating +/- polarity. Smart-search of the ST102 is used to pin-point the location of surveying stakes, pins and objects near chain like fences.
