5. EMI (Electromagnetic Interference)

The searchcoil produces a magnetic field and then detects changes in that

magnetic field caused by the presence of metal objects. This magnetic

field that the detector creates is also susceptible to the electromagnetic

energy produced by other electronic devices. Cell phones, cell phone

towers, power lines, microwave ovens, lighting fixtures, TVs, computers,

motors, etc… all produce EMI which can interfere with the detector and

cause it to beep when no metal is present, and sometimes to beep

erratically.

The SENSITIVITY control lets you reduce the strength of this magnetic

field, and therefore lessen its susceptibility to EMI. You may want to

operate at maximum strength, but the presence of EMI may make this

impossible, so if you experience erratic behavior or “false” signals, reduce

the sensitivity.
