Audio Boost
Boosts the sound of w eak signals receiv ed from small or deep t argets
making it easier for you t o det ect those uncert ain t argets. It is activ e
in the All Met al and Expert modes. It is recommended that audio boost
should be used on a t empor ary or as-needed basis because it will not
only boost the t arget signal audio but it will also boost the v olume of
ground noise and f alse signals along with the threshold hum.
Audio Boost consists of 5 le v els. As f act ory def aults, the Audio Boost
le v el is set t o 3 in the All Met al mode and 5 in the Expert mode. T o
increase the Audio Boost le v el, use the plus (+) and minus (-) butt ons.
Discrimination
Discrimination is the ability of the de vice t o ignore all met als belo w a
cert ain T arget ID . In the discrimination process, the filt ered ID r ange
is sho wn on the color ID scale at the t op of the screen with black
color . F or ex ample, if you set the Discrimination t o 30, 0-30 on the ID
scale will be sho wn in black and the de vice will not produce an audio
response for any met als with IDs betw een 0-30.
Discrimination cannot be used in Basic and Ground Anomaly & Ca vity
modes. The f act ory def ault for discrimination is 0 for Expert and All
Met al and 10 for others.
When discrimination is select ed, the colored adjustment bar with a
cursor sho wing the discrimination le v el, is displayed on screen. You
can adjust the discrimination le v el using the plus (+) and minus (-)
butt ons. The adjust ed le v el will be indicat ed by black color on the bar
and it will also be sho wn numerically inside the cursor .
In order t o change the discrimination v alue, press the SETTING butt on
and choose Discrimination. Decrease or increase the v alue using the
plus (+) or minus (-) butt ons. Please remember that cert ain t argets,
other than the ones you w ant t o ignore, may also be missed or their
signals may become w eak er when using the discrimination setting.
In the case of receiving multiple IDs for the same t arget - let' s say 3 5
and 55 - due t o the orient ation of the t arget or the composition of the
met al itself , if you set the discrimination t o 40, because 3 5 will f all in the

St abilizer
This setting is present in the Expert mode and All Met al mode but it
has diff erent functions in these modes :
St abilizer setting in Expert mode :
This f eature has 2 sub-settings: Aut oR eset and St abilizer . These 2
settings are sho wn on the right and left in the same windo w . St abilizer
consists of 5 le v els sho wn in beige, Aut oR eset consists of 3 colors
sho wn in gr ay. The adjust ed le v el of both settings are sho wn in or ange.
If no or ange bar is present, it means that both settings are off .
Aut oR eset and St abilizer cannot be used simult aneously. In other w ords,
when one is activ e, the other one will be off and cannot be used.
Aut oR eset is activ e in the det ection screen with the IPTU sensor only.
St abilizer , on the other hand, can be used in both det ection screens.
These settings are used t o eliminat e the drifts caused by ground and
t emper ature changes. Drifts may happen in the positiv e or negativ e
direction. During negativ e drifts, the Drift-Met al bar at the bott om of
the screen will up t o the left, in the drift direction. Because positiv e
drifts ha v e the same eff ect as met al, these will mak e the bar fill up t o
the right, in the met al direction.
T o eliminat e these drifts, first pull the trigger once t o w ards you and
release it t o manually retune the de vice. If the drifts are subst antial
and retuning does not impro v e the situation, please follo w the st eps
belo w :
If you are det ecting with the IPTU sensor , increase the Aut oR eset
setting gr adually until the drifts are eliminat ed. At le v el 3, the de vice
may miss w eak signals. Therefore, if you suspect the presence of
met al in a spot, decrease the Aut oR eset le v el t o scan o v er the spot
again.
If the drifts continue, you can increase the St abilizer setting t o 5 t o
eliminat e the drifts. As the St abilizer is increased, the de vice may det ect
w eak er signals but will not be able t o det ect the t argets anymore if you
hold the coil st ationary or sw eep back and forth o v er the t arget.
If you are det ecting without the IPTU sensor , you can eliminat e the
drifts by increasing the St abilizer setting only as the Aut oR eset is
not a v ailable in this screen. Therefore, you can set the St abilizer t o
maximum le v els t o get rid of the drifts but k eep in mind that as the
St abilizer is increased, the de vice may det ect w eak er signals but
will not be able t o det ect the t argets anymore if you hold the coil
st ationary or sw eep back and forth o v er the t arget.
IMPOR T ANT! You can increase the St abilizer setting only in the
det ection screen. Once you go t o scan screen, the de vice will set the
St abilizer setting t o 1. Aut oR eset, on the other hand, will st ay at the
last adjust ed le v el.
IMPOR T ANT! When switching from det ection screen with the IPTU
sensor t o det ection screen without the IPTU sensor , do not forget t o
readjust the St abilizer setting!
NO TE : If en vironment al and ground changes do not cause any drifts,
w e recommend that you turn the Aut oR eset and St abilizer settings
off in det ection screens with and without the sensor respectiv ely.
St abilizer in All Met al Mode :
F or the All Met al mode t o perform accur at ely, a st able threshold sound
is necessary. You cannot search in the All Met al mode without ground
balancing. Changes that occur in the soil structure and miner alization
le v els aft er ground balancing, may cause a rise or f all in the back ground
hum and disrupt the threshold' s st ability which will result in f alse
signals and thus missing signals of small met als. St abilizer adjusts the
speed that the de vice reco v ers its threshold hum and eliminat es the
negativ e eff ects of miner alized soils. Increasing the St abilizer le v el in
high miner alization will enable a more st able oper ation by a v oiding f alse
signals. This, ho w e v er , may cause some loss in depth and it is normal.
NO TE : In high miner alization, if you receiv e t oo many f alse signals
without disruption in the threshold hum, lo w er the sensitivity first
before increasing the St abilizer . If the f alse signals continue, set the
sensitivity back t o its original v alue and increase the St abilizer .
If the miner alization is lo w , you can decrease the St abilizer le v el and
sw eep the coil more slo wly for a deeper det ection.
St abilizer consists of 10 le v els. The de vice will st art at le v el 6. It is
recommended that St abilizer should be increased in high-miner alization
and decreased in lo w miner alization.
Audio T one
Allo ws you t o change the t arget audio response t ones and the
threshold sound according t o your pref erence. F or each met al group
(Ferrous, Gold/Non-Ferrous, Non-Ferrous) the frequency can be
adjust ed betw een 1 50 Hz (1 5) and 700 Hz (70).
In the Audio T one f eature, met al groups mentioned abo v e will be
indicat ed by diff erent colors: Ferrous met als by red, gold/non-f errous
met als by yello w and non-f errous met als by green. The cursor on
each met al group will display the frequency of the audio t one.
T o adjust the Audio T one, select the met al group of which you w ant
t o change the t one of , by using the plus (+) and minus (-) butt ons. The
cursor will turn or ange. Then, press the OK butt on and using the plus
(+) and minus (-) butt ons again, adjust the frequency.
Audio T one f eature is not present in the Basic and Ground Anomaly &
Ca vity modes.
If the t one break points of met al groups are changed with the T one
Break setting, the t one frequencies select ed by the Audio T one setting
will apply t o the ne w ID r anges. Det ails about the T one Break setting
are giv en on the next page.
Threshold
In the All Met al Mode, search is performed with a continuous humming
sound in the back ground, also ref erred t o as the threshold sound. The
loudness of this hum directly impacts the det ection depth of smaller
and deeper t argets and it is adjust ed by the Threshold setting. If the
threshold is set t oo high, a w eak t arget signal may not be heard. On the
contr ary, if the threshold is t oo lo w , you giv e up the depth adv ant age
this setting off ers. In other w ords, w eak signals of smaller or deeper
t argets may be missed. It is recommended for a v er age users t o lea v e
this setting at its def ault v alue and for experienced users t o adjust t o
the highest le v el where they can still hear the w eak t arget signals.
When threshold is select ed, the colored adjustment bar is displayed
on screen. Threshold r anges betw een 1-99. The f act ory def ault is set
t o 26. You can adjust the threshold le v el using the plus (+) and minus
(-) butt ons. The adjust ed le v el will also be sho wn numerically inside
the cursor .
Threshold le v el is directly relat ed t o the Sensitivity and St abilizer
settings. Please be sure t o read the relat ed sections of the manual
carefully.
Threshold setting w or ks in the All Met al mode only.
T r acking
When tr acking is on, the de vice continuously tr acks the changing
ground structures and aut omatically reconfigures the ground balance
setting. The in visible changes in ground aff ect the det ection depth
as w ell as the discrimination ability of the de vice so it is possible t o
oper at e the de vice at higher performance using this f eature under
suit able ground conditions.
When tr acking is activ at ed, the w ord ''T r acking'' will be displayed at
the t op of the ground balance windo w and the ground balance v alue
changes will also be sho w in the same windo w .
NO TE : T r acking does not w or k in non-motion modes. When tr acking is
activ e, if you switch t o a non-motion mode, tr acking will be deactiv at ed
and it will aut omatically be activ e again if you switch back t o a motion
mode.
F or more information on tr acking, please ref er t o the rele v ant sections
of the manual.
iMask
It is used t o eliminat e f alse signals caused by ground noise or hot
rocks when searching in F ast or Deep modes. It consists of 3 le v els.
Its f act ory def ault v alue is set t o 1. You can change the v alue using the
plus (+) and minus (-) butt ons. The adjust ed v alue is sho wn in or ange.
If there are no or ange bars, it means that iMask is off .
If the de vice receiv es a lot of f alse signals due t o highly miner alized soil
or hot rocks in F ast or Deep modes, first re-ground balance. If the f alse
signals continue, lo w er the Sensitivity and check again. In case the f alse
signals still exist, try increasing the Discrimination v alue. R egardless of
all these, if the f alse signals still exist, first change the Sensitivity and
Discrimination v alues back t o their pre vious le v els. Then, increase the
iMask le v el until the f alse signals are eliminat ed.
At the maximum le v el of iMask f alse signals will disappear or will be
minimized. Ho w e v er , in some cases, increasing the iMask will result in
loss of depth for cert ain met als such as copper .
NO TE : When det ecting in 20kHz with the INVENIO Pro on w et or highly
miner alized ground, in order not t o miss smaller high conductiv e met als
(silv er , copper etc.) it is recommended not t o increase the iMask le v el t oo
high.
NO TE : If the ground is not highly miner alized or does not cont ain many
hot rocks, setting the iMask t o ''0'' is recommended.
Notch Filt er
Notch Filt er is the ability of the de vice t o discriminat e single or multiple
T arget IDs by not emitting an audio response for them.
Although Notch Filt er may seem similar t o Discrimination at first
glance, these tw o settings ha v e diff erent functions. While the
Discrimination filt ers out all IDs betw een 0 and the set v alue, the
Notch Filt er discriminat es IDs out individually.
With the Notch Filt er , you can reject a single ID or multiple IDs at the
same time. This process does not aff ect any IDs belo w or abo v e the
select ed IDs. F or ex ample, you can filt er out IDs betw een 31-3 5 as w ell
as 50 simult aneously.
Notch Filt er setting is a v ailable in F ast and Deep modes only.
Ho w T o Use The Notch Filt er Setting
Notch Filt er cannot be used within the Discrimination r ange. In other
w ords, if the Discrimination is set t o 1 5, Notch Filt er can only be applied
t o IDs 1 6 or higher . If you w ant t o notch out IDs 1 5 or belo w , first you
need t o change the Discrimination v alue.
T o use the Notch Filt er , press the SETTINGS butt on and using the up
and do wn butt ons, select it from the options. On the colored ID bar on
screen, the first ID that you can filt er out will be displayed inside the
cursor . F or ex ample, if the Discrimination is set t o 1 5, when you select
Notch Filt er , number 1 6 will be displayed inside the cursor .
Let' s say you w ant t o reject IDs betw een 20-25 and 40. Using the plus
(+) and minus (-) butt ons, select number 20 and press OK. The cursor will
turn or ange and number 20 will be mar k ed with a black line on the ID
bar . Then, using the plus (+) butt on, go t o number 25 and press OK. No w ,
the 20-25 int erv al will be mar k ed in black on the ID bar . At the same
time, the first number of the notched out r ange (20) will be displayed
under the bar and the last number of the r ange (25) will be displayed
abo v e the ID bar . No w , using the plus (+) butt on again, go t o number 40
and press OK. Similarly, number 40 will be mar k ed with a black line.
T o accept back the filt ered IDs, select Notch Filt er from SETTINGS. The
cursor will be appear where you last left it and it will be whit e. Using
the plus (+) or the minus (-) butt on, mo v e the cursor ont o the ID you
w ant t o accept and press OK. Along with the cursor , the black line will
turn or ange and the notched out number on screen will disappear .
Iron Audio
It adjusts or turns off the v olume of the lo w iron t one. It consists of 5
le v els adjust able with the plus (+) and minus (-) butt ons. F act ory def ault
is the maximum le v el. The adjust ed le v el is indicat ed with or ange color .
5 is the maximum le v el. As you lo w er it, the audio response v olume
the de vice produces for f errous met als will decrease. When it is off ,
the iron audio will be silenced. In other w ords, the de vice will det ect
f errous t argets, the T arget ID will be displayed on the screen but the
de vice will not produce any audio response.
Iron Audio is activ e in F ast and Deep modes only.
T one Break
In F ast and Deep modes, this setting is used t o adjust the break points
of the t arget response t ones on the T arget ID r ange. T one Break points
are diff erent in these 2 modes. By using the T one Break f eature, for
each met al group (Ferrous, Gold/Non-Ferrous, Non-Ferrous) you can
change the point where the lo w t one changes int o the higher t one.
When the T one Break setting is select ed, the t one break points of the
met al groups will be sho wn inside the cursor on the colored ID bar . There
are 2 t one break points in the F ast mode and 1 in the Deep mode.
T o change the t one break points, go t o the break point you w ant t o
change by using the right and left butt ons and press OK. Then, adjust
it using the plus (+) and minus (-) butt ons. While adjusting, the number
in the cursor will change and the cursor will mo v e on the ID bar .
T o giv e an ex ample for the abo v e explanation; let' s say you are in
the F ast mode and you w ant t o change the T one Break points. First,
select T one Break from SETTINGS. The ID bar and the t one break
points of the met al groups will be displayed on the screen. Using the
directional butt ons, let' s say you increased the f errous met al t one
break point from 40 t o 4 5. Then, you decreased the t one break point
of the gold/non-f errous met al group from 66 t o 55. In this case, the
de vice will produce a lo w iron t one for all met als with IDs less than 4 5,
a medium t one for met als with IDs 4 5-55 and a high t one for met als
with IDs equal t o and great er than 55 (If you ha v e also adjust ed the
Audio T ones, the select ed frequency will apply t o the ne w ID r anges).
