At GDI geophysical instruments we have tested all the 4 probe resistivity geophysical devices available worldwide. Our study results to the QUATROFORCE geophysical locators gold detectors advanced design. A powerhouse for finding treasures and gold ore that outperforms all rivals!



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
