Coin & Jewelry MODE
1. MODE to Coin & Jewelry
2. Trigger (on hand grip) center "primary Search-
ing" position.
3. TRAC to Ground position.
4. GAIN to "P" position.
5. Threshold, adjust for slight hum (edge of
sound).
6. DUAL CONTROL to DISC "P".
7. Pump the search coil on the ground to be
searched until ground ceases to respond.
8. Move the coil just over the ground and listen
for the distinct repeatable beep produced by a good
metal target. It is wise to plant metals just under
the soil to practice on in order to learn to recog-
nize what it will sound like. Planting a metal target
disturbs the ground mineral, which usually reduces
the depth it would have been found in undisturbed
ground. It will take practice to determine the proper
search speed and technique. Do not go too fast. Try
to overlap your sweep path so that you won't miss
the small and/or deeper metal targets.
9. Once a solid repeatable beep is located:
A. Consult the display information.
B. Squeeze and hold the Trigger on the
hand grip and "X" the area to pinpoint and
note how deep you will need to dig listed on
the display.

10. Once a solid repeatable beep is located
A. Push the Trigger forward and sweep the
search coil over the target area.
1. If it still beeps it is likely a coin
worth digging, procede with 2.
a. If it doesn't beep it is in
the Pull Tab range, Squeeze
and hold the Trigger on the
hand grip and check the
depth. If it is shallow (0 - 2
inches) depending on the
hardness of the ground, it is
most likely a Pull Tab and
should be ignored. If it is
deeper (beyond 2 inches)
depending upon the hardness
of the ground, it is likely
heavier gold jewelry and
should be dug.
2. Consult the display information.
3. Squeeze and hold the Trigger on
the hand grip and "X" the area to
pinpoint and note how deep you will
need to dig listed on the display.
11. Heavy Pull Tab. In areas littered with hun-
dreds of Pull Tabs it may be necessary to search
full time in the Trigger forward position and save
your time and efforts digging coins and jewelry that
indicate outside the pull tab range.
11. Ground Mineralization:
A. For Salt/Alkali environments proceed
exactly as above only with the TRAC toggle
in the Salt position.
B. For areas with an abundance of decom-
posed man made iron (which may make
the MXT 300 appear unstable only during
search coil sweeps), proceed exactly as
above only once you pump the loop over the
ground, then set the Trac control to Lock.
