Page 14 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.

Instruction Manual Page 15

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.
