NOTE:
When detecting in areas of extreme mineralization or electrical interference, to
reduce the sensitivity level turn the control in a counter-clockwise direction.
Ground Adjust
(■round Adjust Control
This control allows you to adjust the ground balance of the
Musketeer XS and XS Pro in order to compensate for changes
in the level of ground mineralization. At its most counter¬
clockwise position this control switches into the "Fixed"
position. When in this position, the Musketeer XS and XS Pro
arc fixed ground balance detectors and require no ground control adjustment.
If while detecting in this setting the level of ground mineralization becomes
high, the Musketeer XS and XS Pro will produce "ground noises" or false
signals. To reduce these ground noises, it will be necessary to switch the
detector out of the "Fixed" position and manually adjust the ground balance.
Ground balance can be adjusted in cither "Discriminate" mode or "All Metals"
mode when in the "Ground Adjust Enable" position.
CAUTION
You cannot effectively ground balance the Musketeer XS and XS Pro
while in the "Pinpoint" position. Turning the ground adjust control while
in this position will cause the detector to become very erratic.
Raise and lower the search coil approximately
•A - 6 inches (1-15 cm) above the ground while
listening for changes in sound. Turn the Ground
Adjust control to the most clockwise position.
Slowly turn the Ground Adjustment counter
clockwise while continuing to raise and lower the
coil, until the audio response from
mineralisation is "just" eliminated.
In areas of extreme mineralization, you may not be
able to completely "balance out" the effects of
ground mineralization. In this case, set the Ground
Adjust control to the position where the sound
varies the least as the coil is raised and lowered
and then reduce the level of sensitivity to
compensate for the excess mineralization.

While detecting, changes in the ground mineralization will occur causing the
detector to produce "ground noises". It will then be necessary for you to re¬
adjust the ground balance using the procedure described above.
It is important to note that the more accurately you ground balance the detector,
the deeper you will detect and the more objects you will find.
Discriminate / All Metals Switch
U
Thc Discriminate / All Metals mode sw itch is located in the
center of the control panel and is used to selects cither
"Discriminate" or "All Metals".
_ In "Discriminate" mode, the Discriminate control is active and
can be adjusted so that the Musketeer XS and XS Pro accept or
ignore certain metal objects, as described in the Discriminate section. In this
"hunt" mode, the coil must be moving over the ground to detect a target. If you
stop moving the coil when over a target, the signal will "disappear".
In "All Metals" mode, the Discriminate control has no effect and the Musketeer
XS and XS Pro will respond in the same way to all types of metal. The coil
need not be moving to maintain a target sound. If the coil is held stationary'
over a target, the sound w ill remain. This is ideal for target pinpointing.
"All Metals" mode is also useful if you are searching for ferrous targets. In this
mode the Reset Sw itch is used to help accurately determine the location of the
target center. This is useful to reduce the amount of digging required to recover
the target you have located.
Discriminate control
■
The Discriminate control is located at the bottom right of the
control panel. This control is used when in "Discriminate"
mode to "discriminate" or "ignore" unwanted metal targets.
Metal objects fall into two broad categories: ferrous and non-
ferrous. A magnet can be used to determine if an object is a
ferrous or non-ferrous metal; ferrous metals will be attracted to the magnet
while non-ferrous metals will not.
When in "Discriminate" mode, the Musketeer XS and XS Pro will discriminate
ferrous objects, and only provide a signal from a non-ferrous object. If the
Discriminate control is set to "1", ferrous metals w ill be "ignored" and the
machine will not produce a "signal beep".
