Connect an audio amplifier to the secondary of a 120V12V transformer through an 8 ohm or so power resistor. (A heating element works if you don't have a resistor with enough power rating.

A simple metal detector circuit diagram project is designed using IC 555, as you can see in the 555 timer circuits, these circuits detect the metals and magnets. When a magnet is near to the 10mH choke, the o/p frequency changes. This circuit can be powered from a power supply, which can provide an o/p DC voltage between 6V to 12V. If metal is near to the coil L1, it produces a change of o/p ...
· · Metal Detector Circuit Explanation. When the LC circuit that is L1 and C1 has got any resonating frequency from any metal which is near to it, electric field will be created which will lead to induces current in the coil and changes in the signal flow through the coil. Variable resistor is used to change the proximity sensor value equal to the ...
With 2 Ω circuit resistance and the minimum voltage of 9 Volt, the current over the coil will reach about Ampere in the 250µsec mentioned above, which is more than adequate for a general purpose pulse induction metal detector with deep seeking capabilities. We have now defined the inductance and resistance of the coil, but this doesn't say much of the physical design of the coil if we ...
Yes, most metal detectors can detect power lines as well as far as they are not buried too deep underneath the ground. The signal from the detection device is able to loe underground power lines by penetrating the plastic conduit and detecting the metallic wire present inside the power line. In some cases, the conduit is made from metal, if that's the case, then it becomes all the more ...
· Long Range Metal Detectors are FAKE – Buyer Beware. Many treasurer hunters (especially beginners) have considered a long range metal detectors for searching for a large cache of treasures buried deep in the ground. The devices are "designed" to find a wide range of items such as treasures, metallic minerals and even lost coils deep into ...
Metal Detector Circuit. Metal Detector Circuit Description This is the circuit diagram of a low cost metal detector using a single transistor circuit and an old pocket is nothing but a Colpitts oscillator working in the medium frequency and a radio tuned to the same frequency the radio and the circuit are placed ...
· Since the general rule for the 2Box detectors/attachments is that "the bigger an object, the deeper it is detected", the 2Box detectors are capable of detecting big treasure chests, safes and large metal boxes stuffed with money, and ore veins down to five feet deep (). However, such "big treasures" are extremely rare. This is why the 2Box detectors are used mostly by WWI and WWII .

Deep targets have very low signal responses that are missed by the limited performance of the detector circuits. Targets that would be missed with an ordinary metal detector either because the signal was weak or even not heard at all, are indied clearly by Geo Examiner. It is so sensitive, that even geological features like voids and manmade structures, may be visualized at some degree.
