gold detector circuit

Now it is necessary to reduce the impact of the generator on the receiver. This is done with the help of a box lid. Both devices attached to the lid should be as close as possible to each other. After reducing the impact of interference, the position of the lids of the box and devices on it must be fixed. You can install a wooden spacer or twist this entire structure with insulating tape. The entire structure is attached to the end of a long stick. This is done for ease of search and carrying.

After the manufacture and configuration of the "DIY", it must be tested. To do this, you need to take an object made of gold and put it on the sand. Next, over the location of the object, hold a homemade device. The receiver must respond by the appearance of noise in the air. After detection, you need to test the device's ability to search at different depths. It is also worth experimenting with metals of different composition and volume, for a more accurate determination of precious and black elements in the soil. The range of penetration increase is adjusted using the position of the calculator relative to the receiver. Such a DIY is not able to detect gold at a depth of up to 1 meter. But with its help, you can teach to determine metal objects by noise in the ether, and become infected with the desire to design a more sensitive and powerful device.
