Chapter 1 MXT 300 Assembly
Assembly Instructions
1. Remove all parts from shipping carton and
check the assembly page to make sure all parts are
present.
2. There are rubber washers between clevis/lower
rod and loop ears. Use only nonmetallic washers,
fi ber bolt, and thumbnut to secure loop/search
coil to clevis/lower rod.
3. Unlock "S" rod camlock and insert clevis/low-
er rod into curved "S" rod so that stainless steel
spring clip buttons line up and lock into one of
the adjustment holes in the curved "S" rod. Turn
camlock to secure. The second or third adjustment
holes are suitable for average size adults. Individ-
uals 6' or taller should use the fully extended posi-
tion. Individuals well over 6' tall should purchase
the optional Tall Man Rod.
4. Unravel loop cable and wind the cable around
the clevis and rod assembly, fi rst revolution over
the top of the rod. Wind cable all the way to the
top of the curved "S" rod, about fi ve revolutions.
Use the black cable retainers, one near the loop,
and one near the top of the curved "S" rod, to hold
the loop cable in place.
5. Unlock control box rod camlock and insert
curved "S" rod so that stainless steel spring clip
buttons line up and lock into the rod on top of the
control box. The "S" rod is designed to curve up
toward the display. However, those who prefer to
sweep the loop close to their feet may desire to
assemble the "S" rod to curve down toward the
ground. Turn camlock to secure. Plug loop con-
nector into control box, screw lock ring to secure.
6.
Grip the instrument by the handle, with your
arm in the elbow cup with strap secure, and sweep
the loop/search coil over the fl oor. If the instru-
ment fi t feels uncomfortable, adjust the elbow cup
by removing and repositioning the bolt/thumbnut
and installing in one of the optional positions. If
necessary, readjust clevis/lower rod length with the
spring clip buttons so that the search coil can be
held near the fl oor without requiring stooping over.
7.
Remove the protective paper from the two black
elbow cup foam pads. Carefully align pads on the
inside of the elbow cup, one on each side of the
center rod, and press fi rmly into place.
8. Adjust the elbow cup strap so that it is loose
enough for you to slide your arm in and out with-
out loosening each time you want to set the de-
tector down. The elbow cup strap provides extra
leverage and control. However, some prefer not to
use it.
9. Install battery as described in the next section,
decal facing down, with plastic tab and steel con-
tacts facing toward inside of battery compartment.
10. It should be noted at this point that the detector
may not work as expected indoors due to the high
degree of metals used in modern construction. It
is best to tune and practice out-of-doors to ensure
stable, predictable results. Additionally, freshly-
buried targets will not produce the normal depth
and discrimination results of targets that have been
naturally lost and settled in the ground. Due to the
abnormality caused by digging a hole in the ground
matrix, and the sophistication of the ground rejec-
tion circuitry, it may take a number of years for
freshly-buried targets to respond at true depths and
discrimination accuracy. The best way to determine
true detection depth is in real search conditions.
