A metal detecting system is a system that consists of a metal detector, a buzzer for producing the sound, an LCD display section, and an interfacing element for connecting all the components. A simplest form of metal detector consists of a detector coil for the detection of metal objects, two oscillator sections, a mixer, and an indicating buzzer.
These metal detector circuits are being used in plenty of places. Most of the security officers use it to detect metal devices like guns, knives, etc. A metal detector is a circuit that senses any metallic object close-by. These metal objects are very useful to detect the presence of any hidden object. A simple metal detector uses a 555 Timer ...
While it will make your metal detector more efficient, you also need to balance out costs.one of the main points of the DIY project is to save costs. A Faraday Shield is a device that helps reduce the ground-effect frequency-shift issue. This issue arises because a metal detector scans the ground in a position that is parallel to the ground.

The following circuit is the transmit coil of an IB metal detector. I recognize most of this: an op amp astable with a CE push-pull output stage driving a resonant circuit. But, I have questions. The frequency of the tank is about 27KHz, which I'm guessing is the fundamental frequency of the astable.

circuits accurately enough and the resulting detector was badly affected by signals from the ground ("ground effect"). The Rx coil is therefore damped a little by R7 to increase the bandwidth, and the drop in amplitude is made good by gain from TR3. The circuit must now detect the peak value of the amplified signal and convert this to a d.c ...
