DISCRIMINATOR
Pulse Induction Metal Detector
SDP-2014A

INTRODUCTION
Congratulations on your choice of the DISCRIMINATOR. This
Automatic Full Discriminator is a new generation of pulse
in uction metal etecting instruments.
It is use for locating larger an smaller (3” to 4” [10cm x 12cm])
size targets at greater epths compare to any other conventional
metal etector. The pulse in uction system is evelope to
automatically retune, so that changes in the groun mineralization
an unwante ferrous metal targets are eliminate . The SDP series
Discriminator is a unique combination of technologies that takes
a vantage from other pulse in uction etector technologies to
create an easy to use balance system.
The DISCRIMINATOR works at great epths an ranges by
smooth an stable operation from the control unit in automatic
motion mo e. Target i entification an iscrimination is possible
with the 1m x 1m square PVC coil. Pinpointing is achieve with
the smaller 11” roun shaft-mounte coil.
Ho does the SDP Automatic Discriminator ork ?
The search coil sen s out short magnetic pulses an pro uces a
strong magnetic fiel above the groun . The magnetic fiel
in uces e y currents in the metal objects to be etecte . These
currents generate a secon ary electromagnetic fiel , which flows
outwar from the target. A portion of this secon ary fiel passes
through the antenna win ing. This signal is processe by the
electronics an isplaye by a ticking rate, meter response an
light in ication. The timely ecoupling between the transmitting
an receiving phases allows the SDP series to work with an
increase transmitting an receiving power.

The magnetometer sensor system senses the magnetism of ferrous
fiel s. When the in epen ent magnetometer sensor system senses
the fiel s it isplays a Re LED Light when a target is ferrous.

unit…also mineral rea ings are more issipate ).
INTERFERENCE- Setting for electromagnetic isturbances (i.e.
Power Lines).
DISCRIMINATION SWITCH- This control switch changes
how a “ferrous” metal target is rea an escribe by control unit
etail. Top position “A/D” is to give a RED le lamp in ication
when “ferrous” metal target is receive , along with a removal of
target signal soun when picke up. Switch position center “SA”
is Semi- iscrimination mo e for smaller “ferrous” metal target
trash. Smaller “ferrous” metal targets will show RED lamp
in ication an cut off signal soun ( iscrimination).
Bottom switch position “A/ND” is Automatic iscrimination with
NO au io iscrimination (soun is still hear ) an RED le lamp
is in icate for “ferrous” metal targets.

own knob if unit is active too often.
TRESH-Is threshol or beginning of etection au io (soun ). Set
Threshol to give one or two “ticks” per secon .
RESET- Button to reset control unit in new groun con itions.
Depressing button one or more times is nee e in each new target
area or if any other settings are change . Pressing reset over metal
will ignore similar metal targets. The machine nee s to be reset
over a clear area (not on targets), not inclu ing minerals in
groun .
LED INDICATOR -The re LED light on the intensity meter
in icates that the target within the etection range of the coil is
ferrous. Remember, that after each change of the Delay or
Sensitivity control’s setting, you shoul wait for the fa ing of the

DISCRIMINATION
The DISCRIMINATOR Pulse In uction Metal Detector is
actually a Dual Detector.
Not only is it equippe with Pulse In uction it also has a built in
Magnetometer sensor system to iscriminate out what targets are
ferrous. The Magnetometer sensor system shows Iron (ferrous)
targets in icate by a bright
Re LED light. By having this a itional etector it allows the
user to eci e if the foun target is one of interest to recover.
STANDART DISCRIMINATION SEARCH
(1m x 1m Coil)
The loop cable is embe e in PVC tubes an can be assemble
- 5 -

for use or ismantle for transportation easily an quickly. The
concentrate magnetic fiel of the coil allows an excellent
etection range on relatively small metal objects.
Targets the size of a cash box are clearly etecte from a istances
of 7-8 feet.
Larger Targets like a large metal treasure chest can be etecte at
a range of up to 15 feet or more epen ing on soil con itions. Our
practical tests have proven this universal search coil as the best
one for treasure hunting with the SDP Series.
AUTOMATIC MODE
(1m x 1m Coil)
The etector retunes automatically to the changes of the groun
con itions (mineralization). Keeping constant operational height
an all the slowly changing external electromagnetic fiel s are not
critical for the stable performance of the SDP pulse in uction
system.
REMINDER: Automatic Mo e is motion etection. The search
coil nee s be move completely through the target area.
DETECTION RANGE
Theoretically the etection range increases with the increase
target’s size, time in groun , until the size of the etecte object is
ouble the surface of the search coil. Smaller coils of
approximately 11” iameter have a specific range of objects,
which are etecte well. Continuous wave etector’s sensitivity is
better on small metal targets. Such coils an etectors have
- 6 -

reache their limits with a etection range of approximately 1
meter. Enormously large amounts of metal woul be necessary to
increase their etection range over these limits. The search coil of
the pulse in uction etectors coul be increase to almost any
size, so that a large long ranging magnetic fiel woul be built up.
The SDP series works using a magnetic fiel cause by short
pulses. The large search coil an the low frequency applie make
it capable of penetrating eep into the groun .
An important isa vantage of the other pulse in uction etectors
is that they are not capable of i entifying whether the target is a
ferrous or non-ferrous metal object. It is known that some of the
latest pulse in uction etectors on the market are a vertise to
have this capability. But for the reliable target i entification these
etectors loose about 40% of their etection epth, an often
register the eep nonferrous targets as being ferrous, which is
absolutely unacceptable for the serious treasure hunter. The
systems operation is strongly influence by the size of the metal
target an it’s aging (oxi ation) in the groun . With the SDP
series Automatic Full Discriminator we have trie to avoi all
these isa vantages of the pulse in uction systems for treasure
hunting.
The DISCRIMINATOR with the 1m x 1m coil iscriminates
(currently only square size coils that iscriminates) the unwante
ferrous objects no matter their size an aging in the groun in
almost all cases. When operate in its iscrimination mo e the
etector oesn’t loose its etection epth an oes not make the
mistake to count a non-ferrous target as an unwante ferrous
metal. This unit is very operative an gives a great choice of non-
iscriminating an iscriminating mo es of operation.
The SDP pulse in uction principle offers many other a vantages:
- 7 -

. Large etection range an extreme epth of etection
. Small objects like bottle caps, pull tabs, pieces of aluminum are
rejecte
. The evice can be operate effectively in highly mineralize soil
areas, beaches, fresh an salt waters.
. High quality components are use an all critical parts of the
circuit are esigne to align themselves to signal rift ue to
changing temperatures
. The hot rocks are categorically ignore
. SDP is a professional eep treasure-hunting instrument with its
incre ible epth etecting capabilities.
. The unique automatic motion mo e of operations makes it user-
frien ly even for the beginners
. The evice is the only metal etector that iscriminates unwante
ferrous targets in the arable layer of the groun with no loss of
epth parameters

Do not push the reset button over metal targets. This will clear
them from being seen again.
After re-a justing the elay or sensitivity you may have to push
the Reset button more than once in or er for it to correct against
the backgroun .
DISCRIMINATOR - FIELD GUIDE
1. Assemble the search coil an connect its plug to the jack on the
rear panel of the control box. Lift the coil at the operational height
(3-6 inches) over a place free of any metals.
2. Attach Antenna Belt Straps (2) to coil an a just for
comfortable level (for square coil only).
3. Attach Control Box belt strap to leather case hol er for control
box on si es.
4. Attach battery connector to back of control box for power.
5. To start, all knobs are FIRST set to “0” or off position at
farthest left.
6. Select the three position switch appropriately to etection mo e
esire (see control panel escription). 11” Roun coil has no
effect from switch, as there is no set iscrimination.
7. Stan in working position- level coil istance on both si es- an
AVOID all close metal un er coil for correct balance. Starting
over a metal target will eliminate or ignore such a metal target
when etecte with iscrimination. Only 25% larger target will be
etecte .
8. Turn “Delay” knob to esire position for target etection (see
panel escription for choices of elay). Push the Reset Button.
9.Turn “Interference” knob to center position when no
- 10 -

interference from electromagnetic interferences is present. If
interference is shown from other than groun metal, tune knob
from left to right appropriately until interference is remove ( o
not move other knob positions after setting interference setting.
Push the Reset Button.
10.Turn on unit with “sensitivity” knob to small black ot on SDP
control unit faceplate label as stan ar target operation mo e.
Lower sensitivity at far left for very large or shallow targets, or
highest sensitivity at far right of know position for very small or
eep targets. Too high of a position will set etector off at every
small metal change. Battery voltage is shown in “Battery goo ”
portion of meter by nee le if no charge is nee e . Drop in voltage
will cause incorrect rea ings an balance. Charge if line in ication
is shown below this mark
11. Push Reset button one or more times to balance machine.
12. After following all previous instructions, begin to slowly turn
“Threshol ” to setting where one or two “ticks” are hear . This
shoul leave nee le on meter at or between “0” an “1”.
13. You are now rea y to etect. REMEMBER this is a “motion”
etection system, so o NOT stop when receiving a metal
etection signal. Walk all the way through the target. Mark with
your foot on groun where signal is first rea between coil parts
an once signal stops. This makes TWO si es of a box.
Simply walk the opposite irection of target signal (making 4
si es of a box).
Mark once signal is receive first an then when stoppe . You
shoul have four marks on the groun . You can then pinpoint with
11” coil.
Practical use in the Non-Discriminating
mo e of operation
Searching with the DISCRIMINATOR etector is easy, when two
- 11 -

persons bring the stan ar search coil. One of them carries the
electronics box (at the opposite to the search coil si e an trying to
keep the electronics box as possibly far from the search coil’s
frame), watching the in ications an making a justments uring
operation. You shoul not carry watches, belt buckles or metal
plates in your shoes, as they coul cause false signals if close to
the search coil.
Walk normally, an if the terrain allows it, carry the search coil at
a lowest possible an constant level operational height over the
groun .
The small shallow metal objects will pro uce two peaks of the
ticking-rate/meter eflection. Lifting the search coil coul cut out
such small size objects. There are some trashy areas, where
bringing the coil higher woul be a vantageous. A mi -size
metal object burie at one meter or so, will give a very clear,
istinguishable in ication. A Large metal target eep in the
groun will cause a long in ication over a larger area than the
smaller metal objects.
With some practice you may be able to estimate the epth
(shallow targets only), the size an even the form of the target
etecte . The best way of getting acquainte with your etector
an its responses to ifferent metal targets is to locate your burie
metal pipes aroun your home. Of course, the reaction of the
etector woul be much better if the metal targets have been
burie in the groun for a longer perio of time (like 30 to 50 yrs).
Walk the test area making sure that you are passing all the way
through the target until the unit is quiet again. Make necessary
a justments to your etector, an tune it carefully away from the
targets. Try to carry the coil 2-6” high, if the terrain allows that.
Pass over your burie utilities. Note the ifferences between the
in ications of the targets.
- 12 -

Another metho is to create a test fiel with “Air Targets”. You
create “Air Targets” by placing ferrous an non-ferrous metals
irectly on top of the groun . The targets shoul be 6 to 10 feet
apart.
Being in Automatic Mo e, stop over one of your targets. In few
secon s the etector will tune itself to this metal object. You’ll
then be aware of that through the ticking rate, which has alrea y
become normal, as set by the manufacturer for the Automatic
Mo e. Move asi e. Pass over the same target, this time not
stopping your movement over it, an the etector will register it
again. So, on’t stop the search coil’s movement over a metal
target while operating your etector in Automatic Mo e.
While testing the etector, please note the following:
- Try to keep a constant operational height of the search coil.
- The etector is very stable while in its Automatic Mo e of
operation. SDP successfully compensates the effects of the
changes of the search coil’s operational height, an retunes
automatically to the changes in the groun con itions an to the
slowly changing external electromagnetic fiel s.
- The Discriminator is a typical motion etector. This means that
the search coil shoul be move over an through the metal target,
if you stop your movement, then the etector will automatically
retune itself an you’ll loose the target.
-The loss of epth uring the operation in the Automatic Mo e
coul be ue to incorrect tuning of the etector.
- 13 -

Practical use in the Discriminating mo e of operation
-In the prepare from your test fiel a a ferrous utensil with a
iameter of 5-6” an bigger, an at 6 – 10 feet, some other iron
instruments.
-Tune the etector in the Manual Mo e far from any metals, an
after that switch it to the Automatic Mo e of operation, as
previously one. The “Sensitivity” control is on the OFF position.
Now Passover all the targets repeate ly, moving with a normal
pace. Note, that the etector gives an au io response to all of your
targets in the test fiel . Iron targets are in icate by the re
(ferrous) LED light on the intensity meter. This shoul work most
of the time, it is the magnetometer which iscriminates the ferrous
from non-ferrous metals.
-Turn the Sensitivity control to the MAX position. Wait till the re
light of thein icator fa es. Switch to A/D position of the toggle
switch (full iscrimination).
-Now pass again repeate ly over your sample targets. Note, that
the non-ferrous plates, even if burie eep in the groun , will
pro uce a goo au io response without a re light of the in icator.
-The LED in icator will illuminate on all the remaining iron
targets, no matter their size, an au io iscriminate . The smaller
target won’t pro uce an au io response.
-The bigger targets will pro uce an increasing soun , when you
approach the coil to them, followe by a sharp lapse into silence,
together with an illuminating LED in icator.
-This mo e of operation allows avoi ing the unnecessary igging
of the unwante ferrous targets. The etector iscriminates all the
ferrous objects lying in the upper arable layer of the groun . The
iscrimination is not affecte by the size, the oxi ation an the
aging of the ferrous objects within the etection range of the
- 14 -

coil. But in case there are ferrous instruments or weapons, burie
together with a cache of money, you risk missing the cache,
because of the so calle “iron shiel ” or “mask”-the
iscrimination of the ferrous targets oppresses the etector’s
reaction to the non-ferrous targets. You coul imitate such a
situation, making the following test:
-Take one of your non-ferrous plates an leave it close to one of
the ferrous targets, (knife, gun, an other ferrous weapons or
instruments), then pass repeate ly over the couple of targets an
note that the etector iscriminates the ferrous target, as well as
the non-ferrous plate. You coul keep this target arrangement for
the test of the next mo e of operation.
Switch to the “Semi- iscrimination” or mi le switch position of
the toggle switch. In this mo e of operation all the smaller ferrous
objects within the etection range will be iscriminate . The
bigger ferrous objects, which coul be weapons, instruments,
utensils or iron containers, hi en together with a hoar , are
registere as non-ferrous targets through etector’s au io
response. At the same time the LED in icator prompts the
presence of ferrous object un er the coil. With the toggle switch in
the “SA” Position, pass over the couple of targets (ferrous an
non-ferrous), which you have alrea y arrange . The etector will
pro uce a clear au io response.
General Notes
Interference
In most of the cases interference is ue to magnetic isturbances
like power lines an may make etection ifficult. Heavy current
cables nearby coul cause severe interference. Magnetic effects of
- 15 -

soil, an its high mineralization coul also cause interfering
signals. To re uce them, see “fiel gui e” for etail of interference
removal operation.
Maintenance
Do not store the etector if the evice is wet or irty. Keep the
connectors an jacks ry an clean. In case of malfunction, first
check the battery voltage an the cable connections. Repair work
shoul be carrie out only by traine personnel.
Inexperience intervention woul cause expiry of the warranty.
Tampering with the seals will voi any an all warranties. Either
expresse or implie . Unit has no user serviceable parts. Unit has
no internal batteries.
Batteries
We suggest using a Multi-Meter to test the battery voltage prior to
using instrument.
Overcharging of batteries may cause the unit to cease operation.
You shoul be able to run the instrument for 16-20 hours prior to
recharging the batteries. The batteries are NiMH an o not have a
memory, so you o not have to let the batteries fully ischarge
prior to recharging. Charging time on empty battery is 6 hours.
Storage
Store your equipment in a clean ry place. Excessive moisture
may cause amage to your equipment. Traveling from a col area
to a hot area may cause con ensation. If the con itions for
con ensation are present, give the equipment time to a just prior
to turning on.

Permission an Laws
Prior to searching an igging you must have permission to search
private property from the owner or caretaker. Know the laws that
apply to the area you are going to search in. Laws vary a great
eal with the City, County, State, an Country, regar ing the use
of metal etectors. Be respectful of public an private property,
an the laws,
which govern the use of metal etectors, an fill all holes after
recoveries.
Troubleshooting
My unit oes not maintain its groun balance.
Check the battery. In most cases an un ercharge battery will
cause this to happen.
- or –
There coul be spots of mineral content that you are trying to
balance evice over.
- or –
When balancing unit you are hol ing the unit too high off the
groun , or irectly on the groun . Hol coil 12”–16” (25cm to
35cm) above groun to balance initially.
I foun a metal object, re-tune my etector, now it is gone. Why?
You re-tune the etector while still in the fiel of the metal
target. You have iscriminate out the target you were looking for.
I cannot get the unit groun balance .
A just the Interference. It is possible that you are too close to an
electrical source an the source will have to be tune out by
turning the knob either to the left or the right.
- 17 -

My battery connection keeps coming loose.
With battery isconnecte , open the two prongs on the control unit
to allow for better battery contact.
It beeps an there is no target. Why?
Minerals with roun an square coil are patchy soun an usually
are not i entifiable more than twice.
Why is the “Ferrous LED” not coming on all the time over ferrous
metal targets?
There may be other metals or alloys in the target which are non-
ferrous or the target is freshly burie (less than 10 years).
