GDI Quatroforce Gold Metal Detector Ground Radar

MORE POWER…QUATROFORCE powerful 110 volts “carrier wave” underground signal, scans deeper to ensure that no target is left hidden.

SMART HI TECH MICROPROCESSOR ANALYSER…Analog meters, LED bars, scale knobs from competitor locators belong to the past. QUATROFORCE color LCD reads and displays graphically resistivity TARGET ID values. Also with audio alarm for precious metals. LCD reacts instant and automatic. No manual scales to select, no HI / LO bands, no Target Response Lamps that burn out. QUATROFORCE is a serious yet simple gold detector without bells and whistles.

CUSTOMER FEEDBACK CONSIDERED…We listen to customer complains about geophysical locators that often indicate wetness and large mineral concentrations erratically as gold / precious metals. Now on the QUATROFORCE you can offset the “GROUND ADJUST” setting to reject those false gold readings, and set any bad environment to read like normal soil.

SIMPLE, SPEED UP, USER INTERFACE…Automatic Test Probe Push Buttons instead of switches. Total 6 push buttons for the 6 pairs of probes that are positioned to the ground on a square pattern. No need for extra Bank Switches to isolate the diagonal from the side probe pairs when scanning.

FUNCTION CHECK…Internal programmed Target Dummy Loads for Gold and Iron, are used for testing. No external load testers to connect at the probe jacks. Push the “TEST GOLD” & “TEST IRON” buttons, and check TARGET ID, to assure that QUATROFORCE operates according to specifications.

QUALITY CONSTRUCTION…Durable, laser cut stainless steel panel fixed into a waterproof carry case.QUATROFORCE is a scientific geophysical locator for the detection of treasures, gold, metals, minerals, caves – voids – tombs, subsurface water.

QUATROFORCE emits a powerful electrical signal and scans the total electrical resistance of the ground using 4 ground probes, that are hammered into the soil on a square or rectangular pattern.

The results are displayed on a color LCD as graphics and TARGET ID values. Underground electrical resistance changes with factors like water, metals or caves. QUATROFORCE LCD analyses targets to these categories: caves/voids, inert ground, water, minerals, iron, gold / precious metals. For a successful detection a metal target needs to have a mass about 3 kg or more. Small coins or equal sized surface targets that trouble metal detectors are not located.

That feature is useful for the detection of treasures in depth, as there is no interference from the small and near the surface trash metal objects. It is a truly scientific tool for archaeology, mining industries, geology and treasure hunting, that can be used by just one operator. The most efficient geophysical locator requires not any training nor any experience. Comes with a 12 V / 7,2 Ah battery and a handy fast in-out power supply connector and charger on a watertight case.


Professional metal detectors locate metals buried for many years by detecting subtle environmental changes caused by these metals.

These detectors use bio-energy interaction, ionization technology, electromagnetic field detection, advanced microprocessor analysis, long-term soil disturbance detection, and sensor fusion. The longer the burial time, the easier it is to detect these metals due to more pronounced ion fields and electromagnetic signatures.

Practical Testing Methods:

  • Field Testing in Historic Sites: Test in areas with known buried metal objects, like historical battlefields or archaeological sites (with permission).
  • Using Known Buried Objects: Test in places where long-buried metals are documented, such as old farm fields or construction sites.
  • Avoid Air Testing: Do not test with unburied or freshly buried metals. These detectors work by detecting ionization fields around long-buried metals, unlike hobby detectors.
  • Avoid testing inside houses, buildings, or other structures: numerous cables, electrical systems, and other factors can interfere with the long-range detector's performance.
