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.
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.
