Metal detector
Magnetic-field metal detector: calibrate in a neutral area, move closer to the surface and feel the strong vibration on detection.
Detects metal objects through changes in the magnetic field around the device. Calibrate in a neutral area first, then move towards a surface: a strong vibration kicks in when the magnetic anomaly crosses the threshold you set.

Key features
Ambient magnetic field strength measured in microteslas
Calibration in a neutral area to set the baseline before searching
Sensitivity adjustable to the detection precision you need
Strong haptic vibration the moment an anomaly is detected
Progress bar that rises in real time as you approach a metal object
Why use it?
Locate an electrical cable or a metal part inside a wall before drilling
Set sensitivity to minimum to detect only large metal objects
Calibrate in a neutral area, then sweep a surface to find unusual spots
