AML PRO and AML+ all-material locators from SubSurface Instruments use ultra-high radio frequencies to find differences in subsurface densities to locate PVC and PE pipes and nearly any other subsurface object that has an edge. They are designed to locate subsurface materials indiscriminately, including plastic, metal, wood, cable or pipe in clay, wet soil, snow or standing water. They have lightweight and durable ABS housing construction, advanced microprocessor intelligence technology, USB and headphone connectivity, and a high range of sensitivity levels to eliminate unwanted and inaccurate readings. 855/422-6346; www.ssilocators.com
