SubSurface ML-3SY Underground Magnetic Locator Digital LCD Screen

Description

Subsurface PN: ML-3SY
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, durable, 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. It's waterproof up to 75 feet - a first for the industry - so it can be used in difficult weather and submerged under water. A new feature allows the ML-3 to provide readings that can be heard 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 at depths up to eight feet.
