ML-3S (40”)
The ML-3 is a much-anticipated and welcome addition to the ML family of magnetic locators from SSI. ML-3 magnetic locators represent the best in innovation at work for the water/sewer industry, surveying industry, and military.
That’s because the ML-3 reflects many of the items on our customers’ technological wish lists. The ML-3 short is 40” to meet surveyors’ personal preference, providing an ergonomic, lightweight, rugged, one-handed operation option to traditional magnetic locators. The ML-3 offers unparalleled durability, as all components are housed inside the aircraft-grade aluminum monotube units.
But don’t let its looks fool you. The ML-3S is the only magnetic locator in the world that is 100 percent waterproof, IP68 certified up to 250 feet – a first for the industry – so it can be used in difficult weather and submerged underwater. 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.
