Metal Detector Pro: Find Metal

Metal Detector Pro turns your smartphone into a powerful digital metal detector. It uses your device’s built‑in magnetometer to locate ferrous metals in real time, with clear visuals and audible beeps to guide you to coins, keys, jewelry, or nails around home, in the garden, or outdoors. It also serves as an educational tool by showing how magnetic fields relate to metal objects and by displaying precise µT readings.

How to use: open the app, calibrate by moving your phone in a figure‑8 pattern for best sensitivity, then slowly scan the area while watching the magnetic field strength and listening for beeps to pinpoint a metal item. You’ll see whether the reading is near natural background levels, indicates a nearby object, or signals a close target, making it a fun treasure‑hunt and practical finder for everyday needs.
