  • Page 6: Helpful Hints

    Detecting a Target: After turning on the detector, hold it with coil down to start detection. When target is located, the detector indicates with vibration and bright light. These pulses increase in quantity as the closer the search coil is to a detected target. The quantity of pulses is proportional to the target size and distance.

  • Page 8 Metal detector milestones: Metal detectors are a common treasure hunting tool because of their ability to pinpoint and identify a variety of precious metals. However, the inventor of the first metal detector — Gustave Trouvé — had a more altruistic goal in mind for designing such a device.
  • Page 9 How metal detectors work: Electromagnetism is the scientific principle at work in a metal detector. The standard handheld metal detector used by hobbyists and treasure hunters has two coils — a transmitter coil and a receiver coil. When the detector is turned on, an electric current moves through the outer transmitter coil generating an electromagnetic field (blue line), which pushes out from the bottom of the device toward the ground.
