How to Make a Metal Detector

How-to-Make-a-Metal-Detector

(Modern Survival.org) – When the average person thinks about a metal detector, it’s for searching for buried treasure on a beach. There are, however, a few good reasons why having a metal detector in a SHTF scenario could be advantageous. For example, a metal detector could help you locate a buried cache of survival equipment or scan newcomers for hidden weapons.

Not only do these machines have applications for survival, but they can also be fun to play with in day-to-day life as well. If you find yourself in a situation where a metal detector could be beneficial, but don’t want to run to the store (or can’t), there is an easy way to make one with a few basic components.

The following video explains how to make your own metal detector:

TEST

What you’ll need:

  • A calculator.
  • A small, handheld AM or AM/FM radio.
  • A CD case.
  • TEST
  • Velcro.

To begin, open the CD case and remove the component that holds the actual CD. Stick Velcro on the backs of both the radio and the calculator, then place Velcro onto the CD case, one piece on both halves. Attach both the radio and the calculator to the case.

Turn both the calculator and the radio on. Make sure the radio is set to AM, and adjust this to the highest frequency available that doesn’t have a station playing. Slowly close the case until you hear a high-pitched sound coming from the radio over the static.

When the contraption comes close to a piece of metal, the buzzing sound will increase. This won’t work for deep penetration of the ground, but it could help you find lost items in grass or loose dirt.
