Now that your detector is assembled, batteries inserted and you are familiar with the control
panel, you should be ready to start detecting. This chapter on Quickstart is designed to be
the starting point for all users of the Explorer II.
GETTING STARTED
Display memory
The Explorer II’s factory setting is
to start in Smartfind for your first
detectingsession.
If the alternative Digital display is
the last used, the Explorer II opens
with this screen next time you turn
on the detector. It also retains all
adjustmentsto
settings made in the previous
session(including those
made in Smartfind).

BEGINNER USE
Trying out the detector
Figure 5.2
Don’t try this at home!
If you attempt to begin detecting while you are inside your home,
you will quickly find that there are many metallic objects (such as
nails or reinforcing in the floor) which will result in almost
continuousdetection.There willalso beinterferencefrom TVsets
andotherhouseholdappliances.Placingthesensitivedetectorcoil
nearlarge metallicobjects canresult intemporarysaturationofthe
sensor, meaningthatit then cannotdetect small objects.Therefore
it is best to turn your detector off and head outside, as far away as
youcanfromsourcesofelectromagneticdisturbance.
Sweeping the coil
TheExplorerIIwillperform atitsbestwhenthecoiliskeptinclose
proximitytothe ground.Thiswillincreasedetectiondepthand
response to small objects. Becoming practised at sweeping the
coil is very important, as variation in coil height at the end of each
swingcancause confusingsoundsand reducedetectiondepth.
Each sweep of the coil should overlap the last one (Figure 5.2).
Thiswillensuregoodgroundcoverage.
You think you’ve found something?
Whenanobjectisdetected,theExplorerIIemitsanaudioresponse
andvisuallydisplaysatargetclassificationon thecontrolpanel’s

Before you attempt to pinpoint or recover the object –
which is explained later in this chapter –it is vital you
understand how to interpret these audio and visual
responses.
This is explained over the next few pages.

BEGINNER USE
Audio Overload
Sometimes it is possible that a
large object close to the search
coil will overload the detector’s
electronics. When this happens,
the Explorer II emits a low ‘warble’
which will repeat until the coil is
moved away from the source of the
overload.

Two-dimensional discrimination
Figure 5.3
When an object is detected, Smartfind indicates what kind of
object you have found with a target crosshair. The location of this
crosshair on the Smartfind screen is based on Minelab's unique
two-dimensionalscaleofdiscrimination. Anunderstandingofthis
will be helpful before Smartfind's Iron Mask and Discrimination
functionsareexplained in the next fewpages.
Two-dimensional discrimination explained
QUICKSTART’S SMARTFIND DISPLAY
When first using the detector, you will see the Smartfind screen. Smartfind displays an
object's characteristics using a two-dimensional scale of target discrimination.

•Theobject’s cross-referencedrating isrepresentedby a
‘targetcrosshair’insidetherectangulardisplay area.
Interpreting target responses
Conductivity
•Objectswithhigh conductivity(e.g.large silvercoins,copper
items) will cause the target crosshair to appear at the top of
the Smartfind screen.
•Objects with low conductivity (e.g. small alloy coins, foil) will
cause the target crosshair to appear at the bottom of the
Smartfind screen.
Along with the type of metal, the size of objects will have some
effectontheconductivity ratingfortargets. Generally,the larger
the target, the higher the corresponding conductivity rating (and
proximity of the target crosshair to the top of the screen).
Ferrous content
•Objects with high ferrous content cause the target crosshair
to appear on the left of the screen unless its rating would
situate the object in the dark area of the discrimination pattern
(seepage44).
•Objects with low ferrous content (e.g. jewelry, coins) cause
the target crosshair to appear on the right of the screen.
Thepresetdiscrimination settingisdesignedtosearch forCoins.
NOTE Both ferrous and non-ferrous objects have varying
degrees of inductive response to electromagnetic waves.
This characteristic –in addition to conductivity –allows for
more accurate identification of targets.
QUICKSTART’S SMARTFIND DISPLAY
Discrimination
Discrimination is the ability of a
metal detector to identify the user’s
desired target (e.g. jewelry) and
eliminate signals from unwanted
material (e.g. nails).
The Explorer II can be programmed
in a number of ways to discriminate
againstunwanted targets indifferent
types of ground.
