Sep 01, 2016· Re: Long distance Metal Detector schematic The limit of a good metal detector is about 30 cm in soil with low mineralisation for 1 Euro coin. The equivalent of this is about 40- 45 cm air drtrction.
D.I.Y Gold Detector Schematic. The circuit oscillates at about 140kHz and a harmonic of this frequency is detected by an AM radio. You can simply tune the radio receiver until a squeal is detected. When the search coil is placed near a metal object, the frequency of the circuit will change and this will be heard from the speaker of AM radio.
Apr 16, 2008· Perhaps the schematic is wrong and the emitters should be connected to the +9V. 2. M1 is specificed a 100mA, way too much current for a typical 9V battery. Perhaps it should be 100uA. ... I have recently built this project Negative ION detector following these instructions.
