In Australia, the gold fields contain exceptional levels of mineralisation. CW or VLF metal detectors such as a Eureka Gold or X-TERRA 705 are able to ground balance in this mineralised or hot ground but with some limitations. This ground balance works fine in so-called homogeneous ground, that is ground that shows very consistent …
A gold detector circuit diagram is an electronic map that reveals areas with a higher concentration of metals. Using this map, you can determine where to dig for gold. By using a simple circuit board and a few pieces of electrical equipment, you can transform your basic metal detector into a powerful device capable of detecting gold …

MODIFYING THE CIRCUIT The circuit can be made much more sensitive by replacing the printed circuit coil with 50 turns of wire (0.25mm), 70mm diameter for coil L1 and 5 turns of the same wire for coil L2. The 100R mini trim pot needs to replaced with 1k mini trim pot. Turn the circuit ON and the buzzer will squeal.
