SubSurface Instruments ML-3ST Magnetic Locator for Submerged Objects

SubSurface Instruments ML-3ST Magnetic Locator has a single narrow LCD that is built into the keypad and into the tube with a bar graph that expands according to signal strength and a plus or minus illuminates above the graph to indicate polarity. SubSurface Instruments ML-3ST Magnetic Locator provides zero adjust to remove or compensate for magnetic gradient in the soil.  The ML-3ST short is 40" to meet surveyors' personal preference, providing an ergonomic, lightweight, rugged, one-handed operation option to traditional magnetic locators. The ML-3-ST offers unparalleled durability, as all components are housed inside the aircraft-grade aluminum monotube units. SubSurface ML-3ST is 100 percent waterproof up to 220 feet so it can be used in difficult weather and submerged under water. Plus, its auto-zero feature allows the user to "cancel" ambient magnetics or magnetic gradient in the soil or water. And it's digitally tuned, so it offers unparalleled accuracy in detecting ferromagnetic objects. Includes soft case with carrying straps and inside pocket for batteries and manual.
