Please read the follo wing section very carefully before operating the
device. This is important in terms of getting the best performance out
of your detect or!
WIRELESS CONNECTION AND P AIRING
The INVENIO system box and shaft & handle communicate wirelessly.
Normally, the system box and the shaft & handle are paired before they
are shipped from the factory. Therefore, they will connect directly upon
initial start up.
Please follow the pairing st eps below if there is no connection
established :
1. Be sure that the system bo x and shaft & handle are turned off .
2. While pressing the SCAN butt on on the handle, turn the ON/OFF
switch on the shaft to ON position. The LED on the handle will st art
blinking red.
3. While pressing the Zoom In button on the system box, turn the
system bo x on - do not let go of the button! When the pairing is
successful, the LED will blink green twice and turn off . You can now
let go of the button.
4. Once the pairing is done, the system box and shaft & handle will
connect automatically upon st art up.
NOTE : You may hear the sound of the relay circuit in the shaft during
pairing; this is normal.
You can follo w the st atus of the wireless connection from the WiFi
icon the INFO bar located at the bottom of the screen. If the icon is
green, it means there is connection. If the icon is red, it means there
is no connection.
If the Wireless Shaft Channel is turned off in the OPTIONS, the
connection will be lost, the LED on the handle will st art blinking red
and the WiFi icon on the INFO bar will turn red as well.
Similarly, if the connection is lost due to any reason, the LED on the
handle will st art blinking red. When the connection is reestablished,
the LED will blink green twice.
SEARCHING
All modes of the INVENIO, except for the Ground Anomaly & Cavity,
work in 2 different det ection screens - one with and one without the
IPTU sensor . The Ground Anomaly & Cavity mode will wor k in the
detection screen with the sensor only. Det ection screen selection
does not ha ve direct effect on the operation of the modes. The main
difference between the 2 screens is as follows: When searching in the
detection screen without the IPTU sensor , the device detects t argets
and displays their IDs only. On the other hand, while searching in the
detection screen with the IPTU sensor , apart from the IDs, the device
also provides the inst ant depth, shape and 3D gr aphs of det ected
targets.
SEARCHING IN DETECTION SCREEN WITH IPTU SENSOR
A. SENSOR CALIBRA TION
1. First, adjust the shaft length and coil angle to searching position.
Then place the search coil on a flat surface, adjust the search coil angle
so that it is parallel with the ground and lean it against a fixed object
such as a tree, rock or a wall. If there is no place to lean it against, hold
it stable with your hand.
2. T urn both the system box and shaft & handle on.
3. Press the SETTINGS button and select ''Calibrat e the sensor''.
4. Press the OK button and wait for the calibration process to be
completed. Once the progress bar is full, the calibration will be
completed and the device will automatically revert t o the select ed
mode's det ection screen.
NOTE : If you will search using the det ection screen without the IPTU
sensor , you do not need to do the calibr ation process.
B. GROUND BALANCE
Especially if you will use one of the non-motion modes, you must
ground balance the detect or before starting t o search. Ground
balancing plays a big role in minimizing the f alse signals and obtaining
target shapes. All details regarding ground balance are explained in
the relevant sections of the manual.
C. SEARCHING
T o obtain accurat e data in the detection screen with the IPTU sensor ,
first be sure that the IPTU sensor is properly calibrat ed.
While searching in this screen, the height of the coil above the ground
is critical for the sensor to obtain accurat e data. For this reason, pay
attention to the height indicator on the screen. The ideal search height
is shown with green on the indicator . T o obtain the best results while
searching and scanning, pay attention to keeping the search coil within
the green area.
While searching in this screen, you can see the movements of the
coil in real time on the 3D detection ground. As the search coil mov es
forward or back, the 3D detection ground will slide. The areas scanned
over by the search coil will be paint ed in gray on the screen. You can
see how much area you hav e scanned by zooming in and out on the
ground. When you zoom in or out on the ground, the target signals and
the search coil will also be zoomed in or out. Zoom does not affect the
scaling of the ground. For example, if the search coil scans an area of
1 meter while you zoom in or out on the ground at maximum, the tot al
scanned area will still be shown as 1 meter on the result screen.
TRACE function : When you press the TRACE button and activate this
function, the screen will follow the coil and rotat e in the same direction.
When you press the TRACE button, the word TRACE will be displayed
on the INFO bar.
When you detect a target in the det ection screen with the IPTU sensor ,
the target ID will be displayed on the cursor on the color ID bar at
the top of the screen. At the same time, the signal obtained from the
target will be displayed with a 3D graph and colored according to the
type of target. Ferrous met als are indicated with red, gold/non-ferrous
metals with yellow , and non-ferrous met als are indicated with green. In
addition, the depth of the detected t arget will be shown on the depth
indicator instantly.
While searching in this screen, drifts may happen in both directions
on the Drift-Metal bar at the bottom. When the bar fills up in the Drift
direction, nothing will be displayed on the 3D detection ground, and the
device will not produce any audio. When the drift happens in the metal
direction on the other hand, a flat, continuous graph will appear on the
detection ground, and the device will produce an audio response.
In such a case, pull the trigger towards you once and release it to
manually retune the device. If the drifts are still present, you can use
the AutoReset and Stabilizer settings to eliminate the drifts. Please
read the relev ant sections of the manual for more det ails.
The 3D signal graph will stay on screen as long as you do not move
the search coil. Once you move the coil, it will stay on screen for about
3 minutes and then disappear . As the 3D detection ground slides, the
signals may fall outside the screen. If you go back to the spots where
you obtained the signals within 3 minutes, you can see the 3D graphs
again.
In detection screen with the IPTU sensor , you can use the CLR button
to clean the screen. Each time you press the CLR button, all dat a on
screen will be erased and the search coil will go to the origin and will
be centered on screen.
You can magnify and reduce the target signals with the up and down
buttons.
The usage details mentioned above are common for all modes except
for the Ground Anomaly & Cavity mode. For Ground Anomaly & Cavity
mode, please read the next section.
Searching in Ground Anomaly & Cavity Mode
The most important thing you need to know before using this mode
is that this mode, different than the other modes, is not a ''detection''
mode but rather a ''survey'' mode. In this mode, the device will detect all
ground anomalies and cavities. Anomalies include, but are not limited to
the below: Different soil types within the same area, mineralized rocks,
disturbed ground etc. etc. Similarly the cavities can be listed as: Rooms,
tunnels, caves, cellars and graves underground. It is recommended that
this mode should not be used in random fields but only in places with
limited size where you suspect the presence of a cavity.
Before starting to use this mode, first be sure that the IPTU sensor is
properly calibrated.
Retune height will be shown on the height indicat or . By lifting the coil
up to the retune height, pull the trigger back once and release. The
sweep height will be mark ed on the height indicator . Lower the coil to
the sweep height and start searching. While searching, the coil must
stay within the green area on the indicat or . This is very import ant for
the device to perform correct computations.
In the Ground Anomaly & Cavity mode, all signals obt ained from
ground with the movement of the coil (ground eff ect, ground anomaly,
cavity or met al), are indicated by painting on the screen. When you
first start searching, the 3D gr aph of the signal obtained from ground
appears bigger and stronger for a short period of time. Then it goes
back to normal. For the device t o perform accurate comput ation in this
mode, it has to collect dat a for a certain period of time. Therefore, it is
recommended that you scan an area of minimum 5-10m² (54-108ft²)
around the suspected area.
In this mode, ground effect is indicated by yellow , metals and positive
hot rocks by red, and ground anomaly and cavity are indicated by gray
or blue color , based on the strength of the signal. In high mineralization,
the device may paint in red color just like in positive hot rocks.
In addition, the signals of targets painted in red are shown with a peak
facing upwards and the signals of targets painted in gray and blue are
shown with a pit facing downwards.
In this mode, the device does not pro vide any audio response. All
targets and signals are only shown visually on screen. F or this reason,
you must follow the screen carefully while searching in this more. If
needed, you can zoom in and out on the screen.
If a met al or a positiv e hot rock is detect ed, the t arget ID will be
displayed on the ID bar at the top. The t arget ID bar in this mode is
white and not colored lik e the other modes.
NOTE : In this mode, t argets with IDs between 0-10 or above 97
indicate positive hot rocks. Sometimes miner alized and volcanic rocks
may generate such IDs and the presence of ground anomalies is v ery
common around them. Therefore, cavity signals obt ained in such areas
may not always belong to real cavities.
The 3D signal graph will stay on screen as long as you do not mo ve
the search coil just lik e in the other modes. Once you move the coil,
it will st ay on screen for about 6 minut es and then disappear . As the
3D detection ground slides, the signals may fall outside the screen.
If you go back to the spots where you obt ained the signals within 6
minutes, you can see the 3D gr aphs again.
SCANNING WITH IPTU SENSOR
Scan function w orks in non-motion modes only. The device will not
switch to scan screen in motion modes!
T o be able to obt ain the 3D graphs and the shapes of the detect ed
targets in the search screen with the IPTU sensor , you must perform
a scan. In order to do this, please follow the st eps below :
a. First, step a way from the area where you get the target signal.
b. Then, press the scan button once and release. The device will switch
to the scan screen. Different than the detection screen, the scan screen
is a white, chequered ground.
c. Press and hold the clear button. When you see the coil centered on
the screen, release the button.
d. By pressing and holding the scan butt on, swing the coil left to right
slowly and scan over the target, starting from a bit a way from where
the signal is st arting and until the coil is completely off the t arget
signal. The most import ant things you should pay attention to while
scanning are holding the search coil st able and parallel to the ground,
and slightly ov erlapping each sweep with no gaps in between. You
can see the gaps clearly on screen. If you are in the Ground Anomaly
& Cavity mode, k eeping the search coil height within the green area
on the indicator is also v ery important.
NOTE : Do not let go of the SCAN button as long as you hear the target
signal. If the SCAN button is released and pressed again, the shapes
will not be correct and there will be gaps between the start and finish
points of the scan.
Except for the Ground Anomaly & Cavity mode, the areas where the
device receives a signal will be paint ed in red. In the Ground Anomaly
& Cavity mode, on the other hand, when you first start scanning, the
painting will be in red or blue for a short period of time independent
from the t arget. Then the painting will be done according t o the met al
type just lik e in the search screen.
TIP : Once the scanning is complet ed, if you swing the search coil o v er
the edges of the scanned area with short sw eeps and clean out the
spots with no t arget signals, the de vice will obt ain a much bett er r a w
dat a.
e. Once the scanning is complet ed, release the scan butt on.
If you w ant, you can scan multiple t argets at the same time by holding
the SC AN butt on pressed or scan them one by one by pressing and
releasing the SC AN butt on each time. In each case, the 3D gr aphs and
shapes of all t argets will appear in a single result screen.
NO TE : T argets with a signal strength of more than 40 on the
Drift-Met al bar locat ed on the bott om of the screen (not present in
the Ground Anomaly & Ca vity) will yield bett er shapes. F or w eak
signals with a signal strength of less than 40, you can increase the
sensitivity t o boost the signal strength.
NO TE : In the scan screen, if you scan o v er the t argets without pressing
the SC AN butt on, the de vice will produce an audio response but will not
paint on screen. If you press the OK butt on in such a case, the de vice
will go t o the result screen but the screen will be blank.
The timing for refreshing the scan screen (dat a t o be er ased from
screen) is around 8 minut es for non-motion and motion modes and
around 1 6 minut es for the Ground Anomaly & Ca vity mode. In the
scan screen, diff erent than the det ection screens, the visible parts of
the screen will be cleared.
IMPOR T ANT! If strong drifts occur once you go t o the scan screen,
first pull the trigger t o w ard you once and release t o manually retune
the de vice. If the drifts are still present, press the B A CK butt on t o go
t o the det ection screen. Then press the SETTINGS butt on, select the
Aut oR eset option and adjust it t o a le v el t o eliminat e the drifts. In case
the drifts are still present, go t o the scan screen, press the SETTINGS
butt on and lo w er the sensitivity le v el.
IMPOR T ANT! If o v erload occurs in the scan screen, you need t o press
the SETTINGS butt on and lo w er the sensitivity.
T o measure the field by scan process :
You can use the scan process just t o measure the field you are in. In
order t o do this, press and hold the SC AN butt on, st art w alking in a
str aight direction and scan without swinging the coil. You can apply
this process in all fields with diff erent shapes, circular or square. Once
the scanning is complet ed, release the SC AN butt on and press OK. An
empty result screen will appear on screen. Press the OK butt on again
and the scanned area will be sho wn linearly. By using the scale on the
screen, you can see the dimensions of the scanned area with 94% -
97% accur acy.
The sample image belo w belongs t o a result screen of a 200x250cm.
(6.7'x8.3') scanned area.
SEARCHING IN DETECTION SCREEN WITHOUT IPTU SENSOR
While searching in the det ection screen without the IPTU sensor ,
all t arget signals including f alse signals are sho wn on a running
oscilloscope windo w with 2D gr aphs. Based on met al type, the t arget
signal is sho wn in the same color as the ID bar at the t op. The IDs
filt ered out by the Discrimination setting are indicat ed by gr ay color
but the de vice does not pro vide an audio response for these t argets.
Upon t arget det ection, the 2D gr aph of the t arget signal will peak
according t o the signal strength. You can magnify or reduce the signal
gr aph with the zoom function. Upon t arget det ection, the Drift-Met al
bar will fill up in the MET AL direction and the ID of the t arget is sho wn
both in the t arget ID windo w at the bott om and with a cursor on the
color t arget ID bar at the t op.
While searching in this screen, drifts may happen in both directions on
the Drift-Met al bar . When the bar fills up in the DRIFT direction, nothing
will be displayed on the oscilloscope and the de vice will not produce
any audio. When the drift happens in the MET AL direction on the other
hand, a flat, continuous gr aph will appear on the oscilloscope, and the
de vice will produce an audio response.
In such a case, first pull the trigger t o w ards you once and release it t o
manually retune the de vice. If the drifts are still present, you can use
the St abilizer setting t o eliminat e the drifts. Ho w e v er , please remember
that as the St abilizer setting 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.
