5. Grip the instrument by the handle, with your
arm in the elbow cup with strap secure, and sweep
the coil over the floor. If the instrument fit 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 sping clip
buttons so that the searchcoil can be held near the
floor without requiring stooping over.
6. 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 detec-
tor down. Peel and stick elbow cup foam pads on
the inside of the elbow cup, one on each side.
7. Install battery as described in the next section,
decal facing down, with plastic tab and steel
contacts facing toward inside of battery compart-
ment.
8 It should be noted at this point that the detector
may not work as expected indoors due to the high
degree of metals ( nails, pipes, etc.) used in modern
construction and the presence of electrical interfer-
ence. It is best to tune and practice out-of-doors to
ensure stable, predictable results.
Assembly Instructions
1. Remove all parts from shipping carton and
check the assembly page to make sure all parts are
present.
2. Unlock "S" rod camlock and insert the reduced
end of the center rod into curved "S" rod so that
stainless steel spring clip buttons line up and lock
into the holes in the curved "S" rod. Turn
camlock to secure.
3. Fit the rubber washers between clevis/lower
rod and searchcoil ears. Use only non-metallic
washers, fiber bolt, and thumbnut, to secure loop
to clevis/lower rod. Then insert into center rod so
that stainless steel spring buttons line up and lock
into one of the adjustment holes in the center rod.
Turn Camlock to secure.
4. Unravel cable and wind the cable around the
clevis and rod assembly, first revolution
should be
OVER the top of the rod with some slack before
applying the cable retainer. This is done so that
the search coil can be paddled backwards toward
the rod without putting a strain on the cable.
Wind cable firmly all the way to the handle toggle
switch
. Then plug connector into control box
turn lock ring to secure. To secure cable, wrap
velcro cable retainers around rod and cable, one
near the searchcoil and one near the toggle switch.
