With 2 Ω circuit resistance and the minimum voltage of 9 Volt, the current over the coil will reach about 3.2 Ampere in the 250µsec mentioned above, which is more than adequate for a general purpose pulse induction metal detector with deep seeking capabilities.
Pito, unfortunatelly such a beast does not exist )) The deepest and best detectors in the world are the Australian "Minelab" detectors, but even their 20000$ model detects a big coin 60 centimeters in the soil. The last time I made DIY metal detector it was 30 centimeters deep for a 22mm coin. Not bad for a homemade machine.

Dec 03, 2017· The Metal detector project is designed for metallic body detection by sensing variations in high frequency Eddy current losses. Using an externally-tuned circuit, they act as oscillators. The output signal level is altered by an approaching metallic object. The output signal is determined by supply current changes. Independent of supply voltage, this current is high or low, according to the
UNDERSTANDING THE PI METAL DETECTOR. The down side of PI's. All detectors are subject to external noise, but PI's are extremely temperamental in this regard. The reason PI's are more sensitive to noise is due to the design of the preamp or first amplifier stage.
The advantage of this type of metal detector is simple construction of both the device and the search coil, but a drawback is the high influence of soil conditions to the detector's perform-ance. Transmit/Receive (T/R) Figure 5 shows a block diagram of T/R type metal detector. T/R metal detectors are very similar to IB metal detectors. An oscil-
The golden rule with metal detectors is keep it lightweight. Avoid using heavy materials such as hardwood or perspex. The round search loop needs to be glued of fixed to a wooden/plastic handle, With the circuit board inside a small plastic box at the other end for balance.
