Size And Depth Of Buried Objects; Emi) Electromagnetic Interference - Bounty Hunter Gold Owner's Manual

THE BASICS

4. Size and Depth of Buried Objects

The relative depth of an object is displayed at the left of the display as
a 1 digit number, 0 to 9 inches. The size of an object can be
determined using sweep techniques described later in the manual.

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. 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.
