Check for metal before you drill. The vibration speeds up as you get closer.
Hitting a wire or a water pipe turns a small job into an expensive repair. Sweep the wall for thirty seconds first. The vibration quickens as metal gets closer. ■ Vibration that speeds up You can't see the screen against a wall, so the pulse interval tells you where it is. ■ Reset the baseline Measurement is relative to where you started, so regional differences in magnetic field don't matter. ■ Adjustable sensitivity Response varies with wall thickness and finish. Tune it yourself. ■ Sensor location guide The magnetic sensor sits in a different spot on every phone. We show you where to place it. ■ Privacy The app does not collect location data. Sensor readings are shown on screen only; they are never stored or transmitted. ■ Please note This app uses the magnetic sensor and finds metal only. It cannot detect wooden studs or plastic pipes. Readings are for reference; always verify with professional equipment before drilling.
