The GDI QUATROFORCE is a powerful geophysical locator and gold detector designed for the detection of treasures, gold ore, and various underground targets. Through extensive testing of available 4-probe resistivity geophysical devices worldwide, GDI has developed the QUATROFORCE with an advanced design that surpasses its competitors.
The QUATROFORCE features a powerful 110-volt “carrier wave” underground signal, allowing it to scan deeper and ensure that no target is left hidden. It utilizes a smart hi-tech microprocessor analyzer that eliminates analog meters, LED bars, and scale knobs found in competitor locators. Instead, it incorporates a color LCD screen that graphically displays resistivity TARGET ID values, providing accurate readings. It also includes an audio alarm for precious metals. The LCD screen reacts instantly and automatically, eliminating the need for manual scale selection, HI/LO bands, or target response lamps that can burn out. The QUATROFORCE is a serious and straightforward gold detector without unnecessary features.
Customer feedback has been taken into consideration during the development of the QUATROFORCE. It addresses common complaints about geophysical locators indicating wetness and large mineral concentrations as gold or precious metals. With the “GROUND ADJUST” setting, users can offset these false readings and set any challenging environment to read like normal soil.
The user interface of the QUATROFORCE is simple and efficient, featuring automatic test probe push buttons instead of switches. There are a total of six push buttons corresponding to the six pairs of probes, which are positioned on the ground in a square pattern. There is no need for extra bank switches to isolate the diagonal from the side probe pairs during scanning.
Function checks are made easy with internal programmed target dummy loads for gold and iron. Users can push the “TEST GOLD” and “TEST IRON” buttons to check the target ID and ensure that the QUATROFORCE operates according to specifications. This eliminates the need for external load testers to connect to the probe jacks.
The QUATROFORCE is constructed with high-quality materials, featuring a durable laser-cut stainless steel panel fixed into a waterproof carry case. It is designed as a scientific geophysical locator for the detection of treasures, gold, metals, minerals, caves, voids, tombs, and subsurface water. The device emits a powerful electrical signal and scans the total electrical resistance of the ground using four ground probes that are hammered into the soil in a square or rectangular pattern. The results are displayed on the color LCD screen as graphics and target ID values. Underground electrical resistance changes with factors such as water, metals, or caves. The QUATROFORCE analyzes targets into categories including caves/voids, inert ground, water, minerals, iron, and gold/precious metals.
The QUATROFORCE is designed to detect metal targets with a mass of approximately 3 kg or more, making it efficient for detecting treasures at depth without interference from small surface trash metal objects. It serves as a scientific tool for archaeology, mining industries, geology, and treasure hunting and can be operated by a single user without requiring training or experience. The device comes with a 12V/7.2 Ah battery and a convenient fast in-out power supply connector and charger in a watertight case.
Using a “carrier wave” signal, the QUATROFORCE transmits underground from two probes at a time to six directions in a square or rectangular pattern. The microprocessor technology incorporated into the design provides accurate analyses of voids, water, minerals, iron, gold, and precious metals through color segments and target ID values on the backlight LCD screen.
What sets the QUATROFORCE apart is its automatic operation. There are no adjustments or complex operations required. Simply power on the device and start scanning the underground
