Headphone Jack - Fisher F11 Owner's Manual

PINPOINTING
Crossing the target zone with multiple intersecting sweeps at multiple angles is another
CIRCLING THE T RGET
way to verify the repeatability of the signal and the potential of the buried target. To use
this method, walk around the target area in a circle, sweeping the searchcoil across the
target repeatedly every 30 to 40 degrees of the circle, about ten different angles as you
walk completely around the target. If a high-tone target completely disappears from
detection at a given angle, chances are you are detecting oxidized ferrous metals, rather
than a silver or copper object. If the tone changes at different angles, you may have
encountered multiple objects. If you are new to the hobby, you may want to dig all targets
at first. With practice in the field, you will learn to better discern the nature of buried
objects by the nature of the detector's response.

This detector has a 1/4" headphone jack. It
works with any stereo headphone (not
included) that has a 1/4" plug. When the
headphone jack is connected, speaker
volume is disabled. Using headphones
extends battery life and prevents the
sounds from bothering bystanders.
Headphone use also facilitates detection
of the weakest signals.
For safety reasons, do not use
headphones near traffic or where other
dangers are present. This device is not to
be used with interconnecting or headphone
cables longer than three meters.
The headphone jack has a rubber plug that
will help keep foreign material from entering
the control box.
