Subsurface Magnetic Locator - ML-3L

The ML-3L is designed to meet each surveyor's personal preferences. The durability of the ML-3L can be attributed to the fact that all of its components are housed in aircraft grade aluminum monotube units. ML-3L magnetic locators are great for the water and sewer industry as well as the surveying industry.
