Chapter 6 MXT Searching
The M6 provides good general purpose searching
for a wide variety of targets and environments.
From residential yards, parks and school grounds,
farm fields to beaches (for salt beaches use Beach
Trac setting).
Coins & Jewelry are the primary goals, however,
these settings and features will also respond to any
better alloy including common relics and any other
item made of a valued metal alloy.
The 1st choice a user should consider is the selec-
tion of an appropriate TRAC toggle setting for the
area. The On setting and Beach settings should be
almost self explanatory. If you are searching in
typical ground, use the TRAC On setting. If you are
on a salt water beach or desert alkali, use the TRAC
Beach setting. When to use the Lock setting can be
less obvious. If it seems like something is wrong
with the detector, wildly fluctuating (only while
sweeping the search coil), try the TracLock setting.
If the detector smooths out and starts operating
more predictably, you made the correct choice. If
there isn't any improvement, you may need to either
reduce the SENS control setting counterclockwise
and/or increase the DISC control setting clockwise.
An area littered with man made iron would dictate
the Lock setting. On the other hand an area littered
with small aluminum foil would not, such an area
would dictate the Reduced SENS and/or higher
discrimination settings.
The 2nd choice is SENS. Some areas require, and
some operators just prefer the more predictable
operation reduced SENS settings provide, where as
others prefer to push SENS to the limits of their
patience to find the deepest targets. There is a point
of diminishing returns either indicated by the
display indciating OVERLOAD, or a user missing
targets because they can not sort them out from
sporadic noises experienced at too high of a SEN
control setting.
The 3rd choice is the alternate MODE "Tone I.D."
accessed by pushing the Trigger (on the hand grip)
forward. Many prefer, after locating a target in the
primary Trigger center position, to check targets
with the Tone I.D. Others use the Tone I.D. as their
primary search mode. It depends a lot on the area
and degree of aluminum Pull Tabs present. Remem-
ber, the display will indicate if a metal target is in
the Pull Tab range in either Trigger position. Also
remember a metal target that indicates in the Pull
Tab range however, provides a deep depth indica-
tion, is more likely to be jewelry than a Pull Tab.
There are three types of targets that typically indi-
cate in the Pull Tab range, Aluminum, Lead, Brass,
and Gold. Without consistency in size/shape, all a
metal detector can tell you is that it indicates within
that range of targets. It is up to the operator to
identify the common trash items of each area and
then weigh the likelihood of good targets.
The 4th choice is the level of audio Discrimination.
The "
" setting provides a popular setting rejecting
most iron and small foil and accepting nickels and
most jewelry. Remember you have the display to
further sort out accepted metals. However, if the
common trash of the area consistently produces an
audio to the point of distracting from finding any-
thing at all, an operator can increase discrimination
(clockwise)
and check the area for silver and
copper. If a hot spot of multiple coins is located an
operator may then want to search isolated spots
within that area at lower discrimination settings.
Even with modern discriminating metal detectors, it
takes a good deal of patience to search high trash
areas.
