hello , can anyone help me with a circuit for a for distance (near 30 cm ) regards as well guys as i have many hours spend building homemade , let me tell you some things. the coil is criticall - you can't ballance it propperly
block diagram of metal detector. there are three main parts in the metal detector circuit: the lc circuit, the proximity sensor , output led and the buzzer. the coil and the capacitor c1, which are connected in parallel, will form the lc circuit.
electronic circuit schematics note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy. some circuits would be illegal to operate in most countries and others are dangerous to construct
1. minelab gpx 5000. the gpx 5000 is a pulse induction (pi) detector that features several of minelabs exclusive technologies, including dual-voltage technology (dvt), multi-period sensing, and smart electronic timing alignment. i consider the minelab gpx 5000 to be the best metal detector for gold.
