pinpointers

Pinpointer, also spelled pin-pointer, is a handheld metal detector used by metal detectorists to locate a buried target with pinpoint accuracy after it has been detected by a larger search coil. Pinpointers generally have a compact housing with a tapered, water-resistant tip that can be pressed into soil, sand, or debris to detect nearby metal.

Operation and features vary, but most pinpointers detect metals with a small internal coil near the tip and provide an audible tone, vibration, or LED indicator when metal is detected. Many units offer adjustable or fixed sensitivity, and some include automatic depth cues or pulse-based alerts. They are designed for close-range searches and are often water-resistant or waterproof for use in wet conditions.

Usage and technique typically involve turning on the pinpointer after the main detector signals a target. The user sweeps the area around the signal with the tip until the indicator confirms proximity, helping to localize the exact spot. The dig is then performed with care to avoid damaging the target, and the pinpointer may be used again to confirm the depth and position after partial excavation.

Power, design, and durability are important considerations. Pinpointers generally run on common batteries such as AA or 9V, with some models using rechargeable cells. Features may include vibration alerts, variable audio volume, belt holsters, and auto shutoff to conserve power. Many units are designed to be rugged or waterproof to withstand field conditions and repeated handling.

Variations exist in depth sensitivity, tip design, and user interface. Pinpointers are widely used in treasure hunting, relic recovery, and other metal-detection activities to improve target localization and reduce excavation damage.
