Handheld Metal Detector

The M158.3 metal detector is a device similar to hand-held metal detectors used by guards to search for metal
objects in people’s clothing. The device is able to find metal objects from ferrous and non-ferrous metal at a
short distance. Using this metal detector, you can detect keys, a mobile phone that are under clothing, a metal
profile under drywall. For gaming purposes, children can look for coins hidden under a carpet or in the sand.

Included is a soldered module and a compartment for two AAA finger batteries with a switch. Batteries are not
included. You only need to solder the two wires to the metal detector board and, if desired, fix the battery
compartment to the board with double-sided tape
