The RIDGID MR-10 Magnetic Locator is designed to make finding buried iron and steel objects faster and easier. It accurately locates objects at great depths, isolating only iron-containing objects, and ignoring nonmagnetic metals such as aluminum and copper. It quickly finds buried property-marking pins, paved-over manhole covers, turf-covered valve boxes, septic tanks, cast iron pipe and drainage grates, as well as hidden pipes and studs in buildings. The sensitivity level can be adjusted to identify the precise location of ferrous metal objects at depths of up to 10 feet, depending on the iron content. Its sleek form and ergonomic design also make it easy to handle for surveying, facility maintenance, construction, excavation, general plumbing and public works. 800/769-7743; www.ridgid.com
