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 long is 55", making it the longest magnetic locator on the market. It allows you to make the biggest sweeps possible without compromising on accuracy. The ML-3 long provides ergonomic, lightweight, durable, one-handed operation option to traditional magnetic locators. It offers unparalleled durability, as all components are housed inside the aircraft-grade aluminum monotube units.
But don't let its looks fool you. It's 100 percent waterproof up to 220 feet - a first for the industry - 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.
