Depending on the reason, construction, and type of metal you’re looking for, Zircon offers three different types of metal detectors for your price and needs.
The MetalliScanner® m40 dedicated metal locator solves the difficult problem of finding studs in lath and plaster walls. It finds the pattern of nails that attach the wood lath to the studs and locates ferrous (magnetic) metal up to 4 inches deep and non-ferrous (non-magnetic) metal up to 2 inches deep. Find plumbing, ductwork, rebar, nails, and screws in your walls, floors, and ceilings.
The MultiScanner® i520 OneStep® stud finder is a multi-function wall scanner that finds the center and edges of wood and metal studs and also has dedicated modes to scan for the metal and live AC electrical wiring. The integrated Metal Scan mode detects the presence of ferrous metal, such as rebar, up to 3 inches deep, and can help determine whether the stud you located in Stud Scan mode is wood or metal.
