You can na vigate between the options with the up and down buttons.
Settings appear in whit e when unselected. They turn orange when
selected.
Mode
When you press the SETTINGS button, mode is the first option selected.
Allows you to select the search mode which you have determined based
on targets and your search field. Select the mode using the directional
buttons. The selected mode will be framed in orange and it will be active
instantly! T o exit the screen, press OK, BACK or SETTINGS.
Sensitivity
It is the depth setting of the device. It is also used t o eliminate the
ambient electromagnetic signals from the surrounding environment
and noise signals transmitted from ground.
NOTE : T o obtain maximum depth performance, to eliminate the noise
caused by electromagnetic interference, try shifting the frequency first.
In the INVENIO Pro, when the frequency shifting is not sufficient for
eliminating noise, you can also change the operating frequency (5kHz
/ 14kHz / 20kHz) of the device.
Sensitivity setting r ange is 1-99 and pre-defined for each mode. All
modes st art at def ault settings. They can be manually modified when
necessary. Sensitivity adjustment applies to the selected mode; the
modified setting does not affect the sensitivity setting of the other
modes.
When sensitivity is selected, the colored adjustment bar is displayed
on screen. You can adjust the sensitivity between 1-99 using the plus
(+) and minus (-) buttons. The adjusted level will be indicated by orange
color on the bar and it will also be shown numerically inside the cursor .
NOTE : If the ground is highly mineralized causing the device t o
overload, decrease the sensitivity level until the ''Overload'' message
disappears from the screen.
NOTE : There is no sensitivity setting in the Ground Anomaly & Cavity
mode.
Sensitivity in Non-Motion Modes
Sensitivity in Basic Mode :
The factory default for the sensitivity setting is optimized in this
mode. If en vironmental and ground conditions allow , you can get more
detection depth by increasing the sensitivity setting.
During searching, if sudden changes in weather conditions, different
ground structures or environmental noise is causing negative or
positive drifts, re-ground balance before you change the sensitivity
level. If the drifts continue, pull the trigger towards you once and
release it t o manually retune the device. If the drifts still continue
frequently, drop the sensitivity gradually and re-ground balance.
Sensitivity in Expert Mode :
In cases where you want to change the sensitivity setting (sudden
changes in w eather conditions, different ground structures or
environment al noise) first re-ground balance. If there are many
negative or positive drifts after re-ground balancing, pull the trigger
towards you once and release it to manually retune the device. If
the drifts are still present, select ''Stabilizer'' from the settings and
increase the ''Aut oReset'' lev el.
Despite all of the above-mentioned, if the drifts still exist, set the
AutoReset t o 1, drop the sensitivity gr adually and re-ground balance.
For det ailed information on other settings, please read the relevant
sections of the manual.
If en vironmental and ground conditions allow , you can get more
detection depth by increasing the sensitivity setting.
Sensitivity in Motion Modes
Sensitivity in All Metal Mode :
In the All Metal mode, sensitivity setting causes an increase or decrease
in the popping sounds and false signals. Sensitivity setting is a personal
preference. However , It is important to set the sensitivity setting to the
highest level possible where no major popping sounds are heard to
avoid missing smaller and deeper targets. For example; if the noise level
is suitable for searching and is the same at sensitivity levels 40 and
70, then 70 should be preferred. Using the factory default levels will be
a good starting point until you get familiar and experienced with the
device.
Sensitivity in fast and Deep Modes :
Since the threshold setting is not available in the discrimination modes,
you can increase the depth of the device or ensure noise-free operation
on different grounds only by using the sensitivity setting.
In order to adjust the sensitivity in Fast and Deep modes, first ground
balance while the sensitivity is at its default setting. After ground
balance is completed, hold the search coil stationary or swing over the
ground at search height. Reduce the sensitivity if the device receives
noise. If not (ensure that the Discrimination is also at its default settings
when checking this), increase the sensitivity gradually until there is no
popping sound. If the device starts to receive noise during searching,
reduce the sensitivity gradually.
NOTE : Because the Deep mode offers maximum depth, it is a bit noisier
than the other modes. However , due to the design characteristics of this
mode, the noise will be more in the air versus in the ground. T ak e this
fact into consideration when adjusting the sensitivity level.
Subthreshold
This setting is intended for use by more experienced users; hence it is
present in the Expert mode only.
This setting enables you to see the signals on screen which fall below
the threshold (falses, ground changes and metal) ; hence normally not
audible.
The device sets the threshold and subthreshold levels automatically
according to the sensitivity level. As the sensitivity increases, threshold
level decreases. In other words, the subthreshold area gets narrower .
Similarly, as the sensitivity decreases, the threshold level increases
and the subthreshold area gets wider . In summary, the Subthreshold
setting enables you to see the signals which fall in this area and which
are normally not audible or visible.
Subthreshold setting consists of 10 lev els adjustable with the plus (+)
and minus (-) buttons. 0 is the f actory def ault. As the subthreshold
level is increased, the inaudible signals will be shown in gray color .
The device will not discriminate signals that fall under the threshold level.
TIP : If the signal det ected with the subthreshold setting is large and
you can increase the sensitivity lev el, you can t ak e the signal over
the threshold lev el and mak e it audible by increasing the sensitivity
for an inst ant. This way you can check the signal and see what kind
of a t arget it is.
Audio Boost
Boosts the sound of weak signals received from small or deep targets
making it easier for you to detect those uncertain t argets. It is active
in the All Metal and Expert modes. It is recommended that audio boost
should be used on a temporary or as-needed basis because it will not
only boost the target signal audio but it will also boost the volume of
ground noise and false signals along with the threshold hum.
Audio Boost consists of 5 levels. As factory defaults, the Audio Boost
level is set to 3 in the All Met al mode and 5 in the Expert mode. T o
increase the Audio Boost lev el, use the plus (+) and minus (-) buttons.
Discrimination
Discrimination is the ability of the device t o ignore all metals below a
certain T arget ID. In the discrimination process, the filtered ID range
is shown on the color ID scale at the top of the screen with black
color . For example, if you set the Discrimination to 30, 0-30 on the ID
scale will be shown in black and the device will not produce an audio
response for any metals with IDs between 0-30.
Discrimination cannot be used in Basic and Ground Anomaly & Ca vity
modes. The fact ory default for discrimination is 0 for Expert and All
Metal and 10 for others.
When discrimination is selected, the colored adjustment bar with a
cursor showing the discrimination lev el, is displayed on screen. You
can adjust the discrimination level using the plus (+) and minus (-)
buttons. The adjusted lev el will be indicated by black color on the bar
and it will also be sho wn numerically inside the cursor .
In order to change the discrimination v alue, press the SETTING button
and choose Discrimination. Decrease or increase the v alue using the
plus (+) or minus (-) buttons. Please remember that certain t argets,
other than the ones you want t o ignore, may also be missed or their
signals may become weak er when using the discrimination setting.
In the case of receiving multiple IDs for the same target - let's say 35
and 55 - due to the orientation of the target or the composition of the
metal itself , if you set the discrimination to 40, because 35 will fall in the
filtered range, the signal strength as well as the depth may diminish.
NOTE : Discrimination setting works in versely proportional to depth up
to level 49 in Fast and Deep modes. In other words, as the discrimination
is increased, stability will increase but depth will be reduced and vice
versa. Above 49 though, both depth and noise will increase.
Stabilizer
This setting is present in the Expert mode and All Met al mode but it
has different functions in these modes :
Stabilizer setting in Expert mode :
This feature has 2 sub-settings: AutoReset and Stabilizer . These 2
settings are shown on the right and left in the same window . Stabilizer
consists of 5 levels shown in beige, AutoReset consists of 3 colors
shown in gray. The adjusted lev el of both settings are shown in orange.
If no orange bar is present, it means that both settings are off.
AutoReset and Stabilizer cannot be used simultaneously. In other words,
when one is active, the other one will be off and cannot be used.
AutoReset is active in the detection screen with the IPTU sensor only.
Stabilizer , on the other hand, can be used in both detection screens.
These settings are used to eliminat e the drifts caused by ground and
temperature changes. Drifts may happen in the positiv e or negative
direction. During negativ e drifts, the Drift-Met al bar at the bottom of
the screen will up to the left, in the drift direction. Because positive
drifts hav e the same eff ect as met al, these will mak e the bar fill up to
the right, in the metal direction.
T o eliminate these drifts, first pull the trigger once towards you and
release it t o manually retune the device. If the drifts are substantial
and retuning does not improv e the situation, please follow the steps
below :
If you are detecting with the IPTU sensor , increase the Aut oReset
setting gradually until the drifts are eliminated. At lev el 3, the device
may miss w eak signals. Therefore, if you suspect the presence of
metal in a spot, decrease the Aut oReset level to scan over the spot
again.
If the drifts continue, you can increase the Stabilizer setting to 5 to
eliminate the drifts. As the Stabilizer is increased, the device may detect
weak er signals but will not be able to detect the targets anymore if you
hold the coil stationary or sweep back and forth over the target.
If you are detecting without the IPTU sensor , you can eliminat e the
drifts by increasing the St abilizer setting only as the Aut oReset is
not av ailable in this screen. Therefore, you can set the Stabilizer to
maximum lev els to get rid of the drifts but k eep in mind that as the
Stabilizer is increased, the device may det ect weaker signals but
will not be able to detect the targets anymore if you hold the coil
stationary or sweep back and forth over the t arget.
IMPORT ANT! You can increase the St abilizer setting only in the
detection screen. Once you go to scan screen, the device will set the
Stabilizer setting to 1. AutoReset, on the other hand, will st ay at the
last adjusted level.
IMPORT ANT! When switching from detection screen with the IPTU
sensor to detection screen without the IPTU sensor , do not forget to
readjust the St abilizer setting!
NOTE : If environment al and ground changes do not cause any drifts,
we recommend that you turn the AutoReset and St abilizer settings
off in det ection screens with and without the sensor respectiv ely.
Stabilizer in All Metal Mode :
For the All Metal mode to perform accurately, a stable threshold sound
is necessary. You cannot search in the All Metal mode without ground
balancing. Changes that occur in the soil structure and mineralization
levels after ground balancing, may cause a rise or fall in the background
hum and disrupt the threshold's stability which will result in false
signals and thus missing signals of small metals. Stabilizer adjusts the
speed that the device recovers its threshold hum and eliminates the
negative effects of mineralized soils. Increasing the Stabilizer level in
high mineralization will enable a more stable operation by avoiding false
signals. This, however , may cause some loss in depth and it is normal.
NOTE : In high mineralization, if you receive too many f alse signals
without disruption in the threshold hum, lower the sensitivity first
before increasing the Stabilizer . If the false signals continue, set the
sensitivity back t o its original value and increase the St abilizer.
If the miner alization is lo w , you can decrease the St abilizer level and
sweep the coil more slowly for a deeper detection.
Stabilizer consists of 10 levels. The device will start at level 6. It is
recommended that Stabilizer should be increased in high-mineralization
and decreased in low mineralization.
Audio T one
Allows you to change the target audio response tones and the
threshold sound according to your preference. F or each met al group
(Ferrous, Gold/Non-Ferrous, Non-Ferrous) the frequency can be
adjusted betw een 150 Hz (15) and 700 Hz (70).
In the Audio T one feature, met al groups mentioned abo ve will be
indicated by different colors: Ferrous metals by red, gold/non-ferrous
metals by yellow and non-f errous met als by green. The cursor on
each met al group will display the frequency of the audio tone.
T o adjust the Audio T one, select the metal group of which you want
to change the t one of , by using the plus (+) and minus (-) buttons. 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 feature is not present in the Basic and Ground Anomaly &
Cavity modes.
If the tone break points of met al groups are changed with the T one
Break setting, the tone frequencies select ed by the Audio T one setting
will apply to the new ID ranges. Details about the T one Break setting
are given on the next page.
Threshold
In the All Metal Mode, search is performed with a continuous humming
sound in the background, also referred to as the threshold sound. The
loudness of this hum directly impacts the detection depth of smaller
and deeper targets and it is adjusted by the Threshold setting. If the
threshold is set too high, a weak target signal may not be heard. On the
contrary, if the threshold is too low , you give up the depth advantage
this setting offers. In other words, weak signals of smaller or deeper
targets may be missed. It is recommended for average users to leave
this setting at its default value and for experienced users to adjust to
the highest level where they can still hear the weak target signals.
When threshold is selected, the colored adjustment bar is displayed
on screen. Threshold ranges betw een 1-99. The factory def ault is set
to 26. You can adjust the threshold lev el using the plus (+) and minus
(-) buttons. The adjusted level will also be shown numerically inside
the cursor .
Threshold lev el is directly related to the Sensitivity and St abilizer
settings. Please be sure to read the relat ed sections of the manual
carefully.
Threshold setting works in the All Met al mode only.
T racking
When tracking is on, the device continuously tr acks the changing
ground structures and automatically reconfigures the ground balance
setting. The in visible changes in ground aff ect the detection depth
as well as the discrimination ability of the device so it is possible to
operate the device at higher performance using this feature under
suitable ground conditions.
When tracking is activat ed, the w ord ''Tracking'' will be displayed at
the top of the ground balance window and the ground balance value
changes will also be show in the same window .
NOTE : Tracking does not work in non-motion modes. When tracking is
active, if you switch to a non-motion mode, tracking will be deactivated
and it will automatically be active again if you switch back to a motion
mode.
For more information on tracking, please refer to the relevant sections
of the manual.
iMask
It is used to eliminat e false signals caused by ground noise or hot
rocks when searching in Fast or Deep modes. It consists of 3 levels.
Its factory def ault value is set to 1. You can change the v alue using the
plus (+) and minus (-) buttons. The adjusted value is sho wn in orange.
If there are no orange bars, it means that iMask is off .
If the device receives a lot of false signals due to highly mineralized soil
or hot rocks in Fast or Deep modes, first re-ground balance. If the false
signals continue, lower the Sensitivity and check again. In case the false
signals still exist, try increasing the Discrimination value. Regardless of
all these, if the false signals still exist, first change the Sensitivity and
Discrimination values back to their previous levels. Then, increase the
iMask level until the false signals are eliminated.
At the maximum lev el of iMask f alse signals will disappear or will be
minimized. Howev er , in some cases, increasing the iMask will result in
loss of depth for cert ain metals such as copper .
NOTE : When detecting in 20kHz with the INVENIO Pro on wet or highly
mineralized ground, in order not to miss smaller high conductive metals
(silver , copper etc.) it is recommended not to increase the iMask level too
high.
NOTE : If the ground is not highly mineralized or does not contain many
hot rocks, setting the iMask to ''0'' is recommended.
Notch Filter
Notch Filter is the ability of the device to discriminate 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 hav e different functions. While the
Discrimination filters out all IDs between 0 and the set value, the
Notch Filter discriminates IDs out individually.
With the Notch Filter , you can reject a single ID or multiple IDs at the
same time. This process does not affect any IDs below or above the
selected IDs. For example, you can filter out IDs betw een 31-35 as well
as 50 simult aneously.
Notch Filter setting is av ailable in Fast and Deep modes only.
How T o Use The Notch Filter Setting
Notch Filter cannot be used within the Discrimination range. In other
words, if the Discrimination is set to 15, Notch Filter can only be applied
to IDs 16 or higher . If you want to notch out IDs 15 or below , first you
need to change the Discrimination value.
T o use the Notch Filter , press the SETTINGS button and using the up
and down buttons, select it from the options. On the colored ID bar on
screen, the first ID that you can filter out will be displayed inside the
cursor . For example, if the Discrimination is set to 15, when you select
Notch Filter , number 16 will be displayed inside the cursor .
Let's say you want to reject IDs between 20-25 and 40. Using the plus
(+) and minus (-) buttons, select number 20 and press OK. The cursor will
turn orange and number 20 will be marked with a black line on the ID
bar . Then, using the plus (+) button, go to number 25 and press OK. Now ,
the 20-25 interval will be mark ed in black on the ID bar. At the same
time, the first number of the notched out range (20) will be displayed
under the bar and the last number of the range (25) will be displayed
above the ID bar . Now , using the plus (+) button again, go to number 40
and press OK. Similarly, number 40 will be mark ed with a black line.
T o accept back the filtered IDs, select Notch Filter from SETTINGS. The
cursor will be appear where you last left it and it will be white. Using
the plus (+) or the minus (-) button, mov e the cursor onto the ID you
want to accept and press OK. Along with the cursor , the black line will
turn orange and the notched out number on screen will disappear .
Iron Audio
It adjusts or turns off the volume of the low iron tone. It consists of 5
levels adjustable with the plus (+) and minus (-) buttons. Factory default
is the maximum level. The adjusted level is indicated with orange color .
5 is the maximum level. As you lower it, the audio response volume
the device produces for ferrous metals will decrease. When it is off ,
the iron audio will be silenced. In other w ords, the device will detect
ferrous t argets, the T arget ID will be displayed on the screen but the
device will not produce any audio response.
Iron Audio is active in Fast and Deep modes only.
T one Break
In Fast and Deep modes, this setting is used to adjust the break points
of the target response t ones on the T arget ID range. T one Break points
are different in these 2 modes. By using the T one Break feature, for
each metal group (Ferrous, Gold/Non-Ferrous, Non-Ferrous) you can
change the point where the low tone changes into the higher tone.
When the T one Break setting is selected, the tone break points of the
metal groups will be shown inside the cursor on the colored ID bar . There
are 2 tone break points in the Fast mode and 1 in the Deep mode.
T o change the tone break points, go to the break point you want to
change by using the right and left buttons and press OK. Then, adjust
it using the plus (+) and minus (-) buttons. While adjusting, the number
in the cursor will change and the cursor will move on the ID bar .
T o give an ex ample for the abov e explanation; let's say you are in
the Fast mode and you want to 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 buttons, let's say you increased the ferrous metal t one
break point from 40 t o 45. Then, you decreased the tone break point
of the gold/non-ferrous met al group from 66 to 55. In this case, the
device will produce a low iron tone for all metals with IDs less than 45,
a medium tone for metals with IDs 45-55 and a high t one for met als
with IDs equal to and greater than 55 (If you hav e also adjusted the
Audio T ones, the selected frequency will apply to the new ID ranges).
Save
INVENIO allows you to save your settings during searching. Once you
saved your settings, the device will st art with the saved settings upon
next start up.
Save function saves the changes made in other modes as well,
regardless of the mode you are in when you perform the save
function. The device starts in the last mode where the sav e function
was performed.
Save function sav es all settings except for the ground balance, tracking
and frequency shift.
pro vide accur at e dat a. F or this reason, you must calibr at e the sensor
upon st art up.
First, adjust the shaft length and coil angle t o searching position. T o
calibr at e the sensor , place the search coil on a flat surf ace, adjust
the search coil angle so that it is par allel with the ground and lean it
against a fix ed object such as a tree, rock or a w all. If there is no place
t o lean it against, hold it st able with your hand. Press the SETTINGS
butt on and select ''Calibr at e the sensor''. The message ''Please place
the coil on a flat surf ace as sho wn in the figure and press o k will be
displayed on screen. Press the OK butt on. You will see the message ''
Calibr ating the sensor , please w ait.'' Once the progress bar is full, the
calibr ation will be complet ed and the de vice will aut omatically re v ert
