GDI Pro-Accumaster VII Metal Detector Ground Radar
Pro Accumaster VII is a geological gold detector that is also designed for the reliable location of ground voids, popular places for hiding gold treasures (caves, tunnels, bunkers, tombs etc). Pro Accumaster VII will locate only large masses of gold,metals, mineral ore and subsurface water. Pro Accumaster VII geophysical gold detector has been proven in archaeology, geology, mining, gold & treasure hunting applications. The advantages of a geological detector like Pro Accumaster VII compared to the hand held metal detectors is the total rejection against small objects buried near the ground surface.
Metal trash fragments, gun shells, aluminum foil do not interfere while hunting for the large, deep buried gold targets, such as a treasure chest. The usage of Pro Accumaster VII geological gold detector is simple, therefore does not require an experienced user. The geological detector panel is built in a waterproof carry case, that includes an external 12 volt / 7,2 Ah battery.
For the location, the supplied 4 ground rods are hammered into the soil, in a square format covering the uspected area, up to 314 sq. meters. Each ground rod connects through a wire to the geological detector panel, where every probe pair has a numbered test switch. Total 6 switches for the 4 sides and the 2 diagonal pairs (X readings) of the square. By pressing its correspondent test switch, all probe pairs. one by one, transmit a high electrical voltage known as “carrier wave” into the ground. The Pro Accumaster VII geological gold detector instantly measures and displays on a target meter, the total electrical resistivity value received from the area between those probes.
The underground resistivity changes with factors like voids, metals or water. Target meter features a scale in OHM resistivity values with colored categories for metals (gold, silver, copper, iron) minerals, water deposits and ground voids.
PRO-ACCUMASTER VII GEOLOGICAL GOLD DETECTOR OHM TARGET METER
To start the detection, hold a test switch for 2 seconds and determine target location within a 314 sq. meter scan area, and up to 3421 sq. meters area with extension wire.
- Voids (black).
- Inert ground (white).
- Water (blue).
- Minerals (brown) .
- Iron (green).
- Precious metals / gold, copper, silver(yellow).

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.
