The threshold in this mode is internal and cannot be adjusted by the
user . Changes in the ground and temperature may lead to drifts in the
threshold. Threshold drifts will be reflected in the bar at the bottom
either in the negative way (in the DRIFT direction) or the positive way
(in the MET AL direction). The device emits an audible response in the
positive drifts and shows the target signal. T o differentiate between a
positive drift and a metal signal, pay attention t o the tone as well as
the signal graph. If the audio response as well as the signal graph are
stretching out uninterruptedly, the chances that the signal is a positive
drift, are high.
During negative drifts, on the other hand, the bar will fill up in the
DRIFT direction but the device will not emit any sounds. T o eliminate
drifts, pull the trigger tow ards you once and release it to manually
retune the device. Retuning periodically while searching in this mode
is recommended.
In the Basic mode, if the drifts are subst antial and retuning does not
improve the situation, drop the sensitivity gr adually and re-ground
balance. If the drifts continue, switch to Expert or one of the other
modes to continue your search.
Expert
This mode is designed for more experienced users. Although it w orks
the same as the Basic mode in principle, its advanced settings allow
for a deeper and more st able search on all kinds of terr ains.
In Expert mode, too, the device will generate the same audio tone for all
targets and it will display the target ID on screen. At the same time, the
target ID will be shown on the color ID scale at the top with the cursor .
In Expert mode, the target ID range is 00-99. 00-40 are ferrous metals
and 41-99 are gold/non-ferrous metals. In this mode, you can use the
Discrimination setting and discriminate out all IDs between 0 and the
set Discrimination value and search while ignoring these targets.

In the Expert mode, if the drifts are subst antial and retuning does not
improve the situation, please read the section about the St abilizer
setting in the manual.
Ground Anomaly & Cavity
This mode is designed to detect the changes and anomalies in the
ground, as w ell as underground cavities, such as rooms, tunnels, and
cellars. The results obtained in this mode are directly associat ed
with the oper ator's experience level with metal detectors. Evaluating
and interpreting the signals in this mode requires relatively more
practice t o other modes. The device can also detect metals in this
mode. Howev er , it is recommended that this mode should not be used
for general metal detection but only in places where you suspect the
presence of a cavity.
This mode w orks with the det ection screen with IPTU sensor only,
and it is a silent mode. In other w ords, the device does not generat e
an audio response upon detection of an anomaly or a cavity.

SEARCH MODES
INVENIO has 6 search modes, designed for different terrains and
targets. 3 of these modes are static (Basic, Expert and Ground Anomaly
& Cavity) and 3 are dynamic (All Metal, Fast and Deep) modes.
Static modes are non-motion modes. In other words, the device will
generate an audio response when you hold the coil st ationary without
swinging over the target. The audio response increases in volume as
the coil approaches the t arget. These modes are recommended for
larger and deeper met als.
Dynamic modes, on the other hand, are motion modes. You must
sweep the search coil from side-to-side to detect met al. If the search
coil does not move, the device will not provide any audio responses
even if the coil is over a metal t arget. These modes are used to detect
smaller t argets such as coins.
The device will start in Basic mode upon initial start up. T o change the
search mode, press the SETTINGS button and select MODE. You can
navigate between the modes using the right and left buttons and select
the one you wish.
All modes, except for the Ground Anomaly & Cavity, will work in both
screens. The Ground Anomaly & Cavity mode will work in the detection
screen with the sensor only. Detection screen selection does not have
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 targets 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 instant
depth, shape and 3D graphs of detected t argets.
Non-Motion Modes
IMPORT ANT! For a more stable oper ation, try keeping the coil
consistently at the same height abo ve the ground where you retuned
the detect or .
IMPORT ANT! If you retune the detector over met al, the drift will be in
the negative side (in the DRIFT direction on the Drift-Met al bar at the
bottom of the screen) and the device will no longer detect the t arget
until the detector is retuned. In addition, the depth of the det ector will
also decrease.
IMPORT ANT! In non-motion modes, ground balancing is very important
for a deeper and more stable det ection. It is recommended that you
should follow the ground balance window and re-ground balance your
device based on instant ground balance changes.
Basic
This mode is designed for beginners. It does not require much
adjustment and can be used by adjusting the sensitivity setting only.
In Basic mode, the target ID r ange is 00-99. 00-40 are ferrous met als
and 41-99 are non-ferrous met als. In this mode, ferrous metals with ID
numbers between 0 and 40 are discriminated out by f actory default.
Upon target det ection in Basic mode, the bar at the bottom of the
screen will fill up to the right, in the MET AL direction in proportion to
the strength of the signal.
In Basic mode, the device will generate the same audio tone for all
targets but it will display the t arget ID on screen. At the same time,
the t arget ID will be shown on the color ID scale at the top with the
cursor .

Motion Modes
All Metal
Different than the Fast and Deep modes, this mode features a
threshold tone which is continuously heard in the background.
All Metal mode is used in 2 different ways in the INVENIO: 1) with the
Discrimination setting disabled at 0 2) with Discrimination enabled
(non-zero). When the device is first turned on, Discrimination setting
will be off . When the Discrimination is set at 0, the device does not
discriminate t argets and detects all targets (met als, mineralized rocks
etc.). ID of the det ected t arget is shown on the display (except for
negative hot rocks) and the same audio tone is provided for all targets.
The audio tone increases in pitch as the coil approaches the target.
When using the Discrimination setting in this mode, the device will emit
a low ferrous tone for all targets below the adjusted Discrimination
setting level, and a higher tone for all targets above the Discrimination
setting which changes in pitch as the coil approaches the target. Let's
say you set the Discrimination to 20. The device will generate a low
iron tone for all metals with 0-20 ID and a higher tone for all targets
with 21-99 ID. Upon target detection, the threshold will momentarily go
silent and only the target audio response will be heard. The duration of
the threshold's silence is directly related to the level of the Stabilizer .
Sensitivity, Threshold and Stabilizer settings in this mode are optimized
to provide the best performance on different terrains. You can modify
these settings based on ground conditions.
We recommend using the All Met al mode when discrimination is not
important and not using it in hea vy trash areas.
Fast Mode
This is the 3-tone discrimination mode designed for coin hunting
especially in trashy sit es such as parks. In this mode, the device
produces a low tone for ferrous targets with 0-40 IDs, a medium tone
for gold and non-ferrous met als with IDs 41-66 and a high tone for
non-ferrous met als with IDs 67-99 such as silv er , brass and copper .
By using the T one Break feature, you can adjust the break points of
the target response tones on the T arget ID range.
In this mode, you can use the Discrimination setting to ignore unwant ed
targets. The Discrimination default value is set to 10. We recommend
you to change this value according to the type of targets you are
searching for .
Deep Mode
Recommended especially for relic hunting. Due to its depth, this mode
is a bit noisier than the other modes. Howev er , due to the design
characteristics of this mode, the noise will be more in the air v ersus
in the ground. T ake this fact int o consideration when adjusting the
sensitivity level.
In this mode, the device produces a low tone for ferrous t argets with
IDs between 0-40. For targets with IDs 41-99, it produces a higher
tone which increases in pitch as the coil approaches the t arget. By
using the T one Break feature, you can adjust the break points of the
target response tones on the T arget ID range.
In this mode, too, you can use the Discrimination setting to ignore
unwant ed targets. The Discrimination default value is set to 10. We
recommend you t o change this value according to the type of t argets
you are searching for .
IMPORT ANT! You cannot get result screens, meaning 3D graphs, in
motion modes.
