High Gain Operation
The effective range of the locator is increased by turning the Gain control towards HI. A high gain setting is useful for
detecting smaller targets. Due to the increased sensitivity with high gain, the pitch of the output tone may vary due to
the instrument’s orientation relative to the Earth’s magnetic field.

Search Procedure
Set the Gain control for normal operation and hold the
locator just below the large end with the “box” resting
comfortably on the underside of your forearm, as illus-
trated in Figure 2-5. Because the upper sensor is
located near the area where the locator is usually
held, wrist watches may produce unwanted changes in
the signal frequency. Therefore, a watch worn on the
wrist of the hand holding the locator should be
removed. Avoid bringing the locator close to your
shoes, since the might contain magnetic material.
To obtain maximum area coverage, the locator should
be swept from side-to-side with the small end of the
instrument kept close to the ground. A higher
frequency tone from the speaker will be heard when
the locator is closest to an iron or steel object.
When using a high Gain setting, avoid turning the
locator about its long axis. This might produce
unwanted variations in the output signal. The pres-
ence of a ferromagnetic object will be indicated by a
change in the tone of the output frequency.
