Chapter 3 MXT 300 Quick Start Quick Start
Instructions
With the MXT 300 properly assembled and
the batteries installed, follow the instruc-
tions below to start fi nding treasures!
Set the Ground Balance Toggle to the
Ground position. "
Set the Ground Balance Toggle to the
"
Set the Trigger Switch (under the hand
grip) to the center (Primary Search)
position.
Set the MODE toggle to the position that
best describes your searching desire,
Coin & Jewelry, Relic, or Prospecting.
Set the DUAL CONTROL to the DISC
ring " " for Coin & Jewelry and Relic
Mode or to the SAT ring "
" for Coin & Jewelry and Relic
" for
Prospecting Mode.
Turn the GAIN control clockwise until the
power clicks "ON". Rotate the GAIN
control clockwise to "
power clicks "ON". Rotate the GAIN
".
Adjust the THRESHOLD control until you
hear a soft threshold "hum" (faint sound).
Lower the search coil to the ground, then
“pump” the coil up and down 2"-4" a
couple of times and Fast AutoTrac will
automatically balance or track out the
ground mineralization.
Start swinging the search coil in wide
sweeps that overlap each other as near the
ground surface as possible.
If you experience false signals or constant
beeping or popping and you are not near
common sources of electrical interference,
set TRAC to LOCK and/or reduce GAIN
(counterclockwise) slightly and try again.
It is normal to hear very slight fl uctuations
in the THRESHOLD “hum” as the MXT
300 tracks out the ground mineralization.
When operating in the Prospecting Mode,
fi rst try reducing the Gain and/or increasing
the SAT speed. SAT speeds as high as HY-
PERSAT may be necessary in some ground
conditions. If Gain and SAT adjustments do
not smooth performance, then switch to the
Trac Lock position.

* SPECIAL NOTICE
If you attempt to demonstrate or test the
MXT 300 by waving targets in the air in
front of the search coil, it is ESSENTIAL
to have the GROUND BALANCE toggle
in the Lock position, NOT Ground or
Salt.
This is necessary, for when the MXT 300
is in the Ground or Salt positions, the
search coil must SEE ground while it is
passing over the target or it will think
that the target IS ground and will attempt
to track it out. This is the case in all
MODEs.
You may, however, demonstrate the fast
ground balancing feature of Ground or
Salt by waving or pumping a mineralized
rock in the air in front of the search coil.
Testing the MXT 300 with targets while in
TRAC Ground or Salt positions must be
done in or on the ground.
