The Minelab Musketeer Advantage
Typical ferrous objects encountered by treasure hunters are nails, screws,
washers, bits of wire, etc. These objects are generally not considered to be of
value, so it is a distinct advantage to be able to ignore these objects while
detecting in this setting. Objects that will cause the
Advantage
to produce a
“signal beep” will be non-ferrous metals. This includes such items as aluminum
foil, most jewellery, pull-tabs, coins, bottle tops, gold, silver, brass, etc. Not all of
these non-ferrous objects are considered valuable. Therefore, by using the
Discrimination Level Adjust, the
Advantage
can be adjusted to ignore some of
the less valuable non-ferrous objects while still locating the more valuable
targets.
By turning the Discimination Level Adjust control clockwise some non-ferrous
objects of increasing conductivity will be ignored. The
Advantage
uses the
electrical conductivity of the object to determine the type of metal detected and,
based upon the Discrimination Level Adjust setting, will either ignore or accept
the object.
The following diagram shows some common objects and where the
Discriminate control has to be set to ignore them.
Figure 10 - Discrimination Level Adjust control examples
As you can see from the diagram, items such as gold rings cover a large area
of the Discriminate control. This is because fine rings are less conductive than
heavier rings and the higher the purity or Carat (K) rating the higher the
conductivity. Therefore, if you set the Level Adjust control to ignore pull-tabs
you will also ignore some fine rings and other jewellery.

The setting of the Discrimination Level Adjust is relative to the types of objects
that you wish to hunt for, and the amount of trash that you are prepared to
detect. If you do not want to dig old bottle caps but want to dig brass buttons or
copper coins, the Discrimination Level Adjust control is set higher
(approximately at number 7 in Figure 10) but most fine white gold rings, foil and
some yellow gold rings will also be ignored.
Once you have learned where certain trash items are eliminated and where
valuable items are accepted you are then able to decide where to set the
Discrimination Level Adjust control. You should only use as much
discrimination as is required to eliminate the common junk items you do not
want while still accepting the valuable items you do.
Always remember that another person detecting behind you who is willing to
dig a little more trash will find the items you have passed over.
Pinpoint
Pinpoint is the ability to locate exactly where in the
ground your target is. By Pinpointing accurately you are
sure to save time and can remove the target with minimal
disturbance to the environment of the area.
Pinpoint is not normally used while searching. Its purpose
is to locate the precise position of the target after it has
been discovered in one of the search modes.
The Pinpoint feature works only while the
Advantage
is in the “All Metals”
mode. While in the All Metals / Pinpoint mode the
Advantage
is a “non-motion”
detector. This means that the coil does not have to be moving to detect a target
Sometimes when in this mode the Audio volume may become loud and erratic.
If this occurs you will need to retune by pressing and releasing the “Threshold
Reset” function. If this does not solve the problem you may then need to check
the Ground Balance as described on page 12 or reduce the Sensitivity of the
detector slightly.
Threshold Reset
Threshold Reset is located at the centre of the control panel. The switch is
spring loaded and will flip back into its normal position when you release it. This
control is only operational while the Advantage is in the “All Metals” mode and
used in conjunction with the Pinpoint mode as described below to assist in
accurate target location.
