Sep 14, 2011· Pulse Induction (PI) metal detectors are sending repeated pulses of electrical current to the search coil, producing a magnetic field. The coil transmits a pulse toward the ground, generating an answering pulse from the target object.
A: While most metal detectors can detect the presence of gold in a general sweep, many discriminators have difficulty tuning out other metal signatures. This is why dedicated gold hunters often purchase a special metal detector designed to "listen" specifically for smaller gold fragments. Q: Metal detecting seems very straightforward to me.

Magnetic field meter circuit diagram. The diagram clearly shows which LED lights at a given fieldstrength. When D10 lights, the measured fieldstrength >= µV, rather greater than the upper limit specified in MPRII (250 nT). If the meter is linked to a DVM, this must be set to its 200 mV direct voltage range.
The simplest form of a metal detector consists of an oscillator producing an alternating current that passes through a coil producing an alternating magnetic field. If a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal, and this produces a magnetic field of its own.

Metal detector frequencies range between 3 – 100 Khz as a general rule. Low Frequency. Have longer wavelength. Gets greater depth as long waves penetrate the ground more easily. Better for detecting high conductivity targets like silver. Not good for finding smaller targets. Not good for low conductivity targets like gold or Iron.

All metal detectors detect metal just like all cars drive down the road. What makes one detector better than another (like cars) is the additional features and enhancements. Look for a beginner detector in the 150300 range. Anything below that isn't really considered a detector it's considered a toy.
