Cordless Sub-Scanners

section within our Cordless Power Tools department

A traditional hand held metal detector is great for walking along the beach looking for buried treasure, but they're not designed to find metal behind walls. Specially designed cordless sub-scanners make this task a breeze. Their compact easy-to-handle design makes for effortless scanning through concrete, metal, wood, drywall and more. It can detect ferrous metal, non-ferrous metal, wood, PVC and even has a built in non-contact voltage detector to alert you to hidden live current.
