Minelab PRO-FIND 15 Series pinpointers help you to accurately locate targets inside a small hole or crevice where a metal detector coil cannot fit. This results in smaller holes, less environmental disruption, and a faster target recovery time. Now waterproof to 5 feet!

This series of pinpointers features Minelab’s Detector Interference Free (DIF) technology that significantly reduces interference with an operating metal detector, when the pinpointer is switched off, by disengaging the pinpointer coil’s magnetic field. Another great feature that some detectorists may find very useful is a lost alarm that will sound after a period of inactive use. This makes it easy to locate your forgotten pinpointer so you never leave it behind!
