Pinpointing with Mono Searchcoils

First, slowly scan the searchcoil from side-to-side

over the target area, noting the location where the

loudest signal occurs. Then draw an imaginary "X" on

the ground by scanning the searchcoil front-to-back

and again noting the location of the loudest signal.

The center of the "X" is the location of your target.

Note: the Infinium LS is a motion-mode-only

detector; the searchcoil must be moving slightly in

order to maintain detection sound.

. Adjusting Frequency

You can subtly adjust the operating frequency to

reduce interference caused by other detectors or

power lines if needed. To adjust frequency:

Turn the Threshold dial beyond “MAX” to “Freq.

Adjust” and you’ll notice that the audio threshold was

increasing and then abruptly dropped back to a lower

level. The detector is now in a "Frequency Adjustment

Mode".

You can now adjust the operating frequency using

the Discrimination knob. Incrementally adjust the

Discrimination knob, pausing after each adjustment

to listen, until you obtain minimum interference. Note

that there are 32 different frequencies to choose from

so turn the dial in very small steps.
