Ground balance can be performed in three ways with the INVENIO:
Automatic, Manual and Tracking.
The ground balance screen is a separate window in detection screens
(except for the Ground Anomaly & Cavity mode). In the detection screen
with the IPTU sensor, you can remove the ground balance screen by
pressing the INFO button but it is fixed in the detection screen without
the IPTU sensor. The ground balance window is divided into 2 parts:
The top part shows the instant ground balance value changes while
searching and the bottom part shows the adjusted ground balance
value.
If the trigger is pushed forward while performing an automatic or
manual ground balance, the device will switch to All Metal mode
automatically on the background without any indication to the user,
regardless of the selected search mode.
Upon completion of ground balance, the ground balance value is shown
under ''Adjusted'' in the ground balance window.
Automatic Ground Balance
Automatic ground balance is performed as follows in all search modes:
1)
First, find a spot of ground where there is no metal present.
2)
Push the ground balance trigger forward and hold it. The ground
balance screen will be displayed automatically and the word
''Automatic'' will appear bigger on screen.
3)
Hold the search coil parallel to the ground. Continue to push and
hold the trigger forward and start pumping the search coil up and
down from about 20 cms. (~8'') above the ground down to 5 cms. (~2'')
off the ground with smooth movements and keeping it parallel to the
ground (this is also shown by animation on the screen).
4)
Continue until a beep, indicating the completion of ground balance,
is heard. Based on ground conditions, it usually takes about 2-4 pumps
for the ground balance to be completed.
5)
When the ground balance trigger is released, the device continues to
operate in the All Metal mode for a short period of time and the ground
balance window stays on screen. The word ''Manual'' will appear bigger
on screen. This makes it possible to manually fine tune the automatic
ground balance value. Refer to the following "Manual Ground Balance"
section for further information regarding this feature. If no button is
pressed for a while, the device will revert back to the detection screen
automatically. If you do not want to wait for the timeout period, you
can switch to the detection screen by pulling and releasing the trigger
once.
6)
Upon completion of the automatic ground balance, ground balance
value will be shown under ''Adjusted'' in the ground balance window
and it will be same as the ''Instant'' value. The device continues to
ground balance and produce a beep sound as long as you keep the
trigger pushed forward and pump the coil. In order to ensure that
the ground balance is proper, ground balance at least 2-3 times and
check the ground balance values on screen. In general, the difference
between the values shall not be higher than 1-2 numbers.
7)
If you cannot ground balance, in other words, if no beep sound is
produced, it means that either the ground is too conductive or not
mineralized or there is a target right below the search coil. In such
a case, retry ground balancing at a different spot. If you still cannot
ground balance, read the section titled
''Important Details Concerning
Ground Balance''
.
NOTE :
If the Stabilizer value is set high, the device may not auto
ground balance. In such a case, go to the SETTINGS of the All Metal
mode and select Stabilizer. Lower the Stabilizer value first. After
ground balancing, set the Stabilizer value back to its original level.
Manual Ground Balance
Allows you to manually modify the ground balance value. It is not
preferred mostly because it takes time. However, it is the preferred
option in cases where a successful ground balance cannot be
performed using other methods or minor corrections are required for
the automatic ground balance.
INVENIO is designed to allow for automatic ground balancing
conveniently on any type of ground. Therefore, it is recommended
to perform automatic ground balance upon start up. However, the
ground may not be suitable for automatic ground balancing in some
cases and the device cannot ground balance on such grounds. For
instance, wet beach sand, soils containing alkali or salty water,
trashy sites, ploughed fields, highly mineralized grounds and grounds
with very low mineralization are not suitable for automatic ground
balance. In such terrains, you can perform manual ground balancing.
However, manual ground balance requires a skill which develops over
time through practice.
To perform manual ground balance :
1)
First, find a spot of ground where there is no metal present and
switch the device to All Metal mode.
2)
You need to listen to the sounds coming from the ground in order
to perform manual ground balance. Pump the search coil up and down
from about 20 cms. (~ 8'') above the ground down to 5 cms. (~2'') off the
ground with smooth movements and keeping it parallel to the ground.
If the sound gets higher when lifting off the search coil above the
ground, the ground balance value is too low, in other words, the effect
from the ground is negative and the ground balance value needs to
be increased by using the plus ( + ) button. On the other hand, if the
sound gets higher when lowering the search coil to the ground, the
ground balance value is too high, in other words, the effect from the
ground is positive and the ground balance value needs to decreased
by using the minus ( - ) button.
3)
Push the ground balance trigger forward once and release it. The
ground balance screen will open up and stay on screen for a while.
You can return to the ground balance screen by pushing the ground
balance trigger forward if the screen switches.
Manual ground balance functions within the range of 0,00 -99,80.
However, each value covers 5 steps used for fine tuning within itself
and these steps are indicated as multiples of 20.
Press plus ( + ) or minus ( - ) button to increase or decrease the ground
balance value, respectively. If the button is pressed once at a time, the
values count one by one and if it is held down, the values will change
quickly.
4)
Repeat the above procedure until the sound heard from the ground
is eliminated.
The sound may not be eliminated completely in some areas. In these
cases, listen to the sounds produced when moving the search coil
towards and away from the ground to check if the ground balance
is correct. If there is no difference between the two sounds then the
ground balance is set properly.
The device will return to the detection screen automatically after a
short period of time upon completion of ground balance. If you do not
wish to wait for the timeout period, just pull and release the trigger
once to go to the detection screen instantly.
IMPORTANT!
Experienced detectorists adjust the ground balance
setting to a slightly positive response (weak but audible sound is
produced when moving the search coil closer to ground). This method
may produce favorable results for experienced users in certain fields
where small targets are searched for.
Tracking
This feature is present in the Motion modes only and not available in
the Non-motion modes.
In this option, the user does not need to make any adjustments.
Tracking feature is activated by selecting it from the settings of the
motion modes and by switching it to on position. The word ''Tracking''
will be displayed in green at the bottom of the ground balance window.
The device updates the ground balance automatically as long as the
search coil is swung over the ground and shows the ground balance
value in the ground balance window. It does not provide any feedback
to the user (like the beep sound in automatic ground balance).
While tracking is active, the device can initially produce a loud signal
when it detects a different ground structure (for instance a mineral
rock) or a target. In this case, swing the search coil over the spot where
the device produces the signal . If the sound remains the same and
the device shows an ID, it is possibly a target. If the sound attenuates
too much or is lost after a few swings, it means that the device has
produced a signal for the different ground structure or a stone.
NOTE :
It is recommended that you use tracking in the All Metal mode
and not in the discrimination modes.
NOTE :
Tracking is not a mode specific setting, when it is turned on it
will be active in other motion modes as well. If you switch to one of the
non-motion modes while tracking is on, it will be turned off and once
you switch back to a motion mode, it will be active again automatically.
Tracking is suitable for use in areas where different soil structures are
present within the same land or in fields where mineralized rocks are
scattered widely apart. If you use ground tracking in areas where hot
rocks are intensely present, the device may not be able to eliminate
these highly mineralized rocks or you may miss the smaller or deeper
metals.
IMPORTANT!
Ensure that tracking is off during air tests. Otherwise,
the device will attempt to perform ground balance on the target and
the depth will be reduced.
Ground Balance Value
Ground balance value provides information about the ground you are
searching on. Some typical ground types are as follows :
0-25
Wet salt water or wet alkali soils
25-50 Wet salt water and wet alkali soils covered with dry layers
50-70 Regular, low-quality soils
70-90
Highly magnetic soils, magnetite or maghemite and similar
highly mineralized soils, black sand.
Important Details Concerning Ground Balance
1)
Upon start up, the ground balance value is set to 90. The device can
perform ground balance automatically within the following ranges for
each type of search coil :
INV28 search coil : 40,00 - 99,00
INV40 search coil : 20,00 - 99,00
INV56 search coil : 0,00 - 99,00
2)
If the ground mineralization is too low, automatic ground balance
may fail. In such a case, you can try manual ground balancing.
3)
You can test the accuracy of the ground balance with pinpointing
in motion modes. After ground balancing, if you receive no sound or a
weak one when you move the search coil closer to the ground in the
pinpoint mode, then the ground balance is successful. If the sound
gets louder when you move the search coil closer to the ground, then
the ground balance is not successful. In this case, simply change your
location. If ground balance is not possible despite these efforts, you
should continue your search without performing ground balance.
Nemôžete vyhľadávať v režimoch All Metal (všetky kovy) a
bezpohybových (okrem Ground Anomaly & Cavity – Pôdne anomálie
a dutiny) bez vyváženia zeme. Musíte použiť jeden z diskriminačných
režimov a zvyšovať hodnotu diskriminácie, kým sa rušenie neodstráni.
4)
Po nastavení hodnoty vyváženia zeme nie je potrebné ju vo
väčšine oblastiach meniť. Ak sa však stretnete s vykopanou,
zasypanou alebo geologicky zloženou pôdnou štruktúrou, malo by
sa vyváženie pôdy znova vykonať, aby sa prispôsobilo premenlivej
štruktúre pôdy. Okrem toho sa odporúča jej opätovné vykonanie, ak
zmeníte prevádzkovú frekvenciu INVENIO Pro (5 kHz / 14 kHz / 20
kHz) v určitých pôdnych podmienkach.
12
Hodnoty ID neželezných kovov, ako je meď, striebro, hliník a olovo,
sú vysoké. Rozsah ID zlata je široký a môže spadať do rovnakého
rozsahu kovového odpadu, ako je železo, fólia, uzávery z fliaš atď.
Preto, ak hľadáte zlaté ciele, očakávajte, že vykopete aj nejaké
odpadky.
POZNÁMKA: Majte na pamäti, že veľké ciele budú mať hodnoty ID
vyššie, ako by sa očakávalo, aj keď môžu mať nižšiu vodivosť.
DÔLEŽITÉ! INVENIO Pro používa normalizovanú stupnicu ID. Inými
slovami, ID sa pri zmene frekvencie nezmenia a zariadenie
vygeneruje hodnoty ID 14 kHz frekvencie pre každú inú frekvenciu.
V závislosti od pôdnych podmienok sa však ID môžu pre určité
kovy líšiť.
TARGET ID/ID CIEĽA je číslo vytvorené detektorom na základe
vodivosti kovov a dáva používateľovi predstavu o tom, aký môže byť
cieľ. Hodnota ID sa na displeji zobrazuje dvoma číslicami a pohybuje sa
v rozmedzí 00-99.
V niektorých prípadoch môže zariadenie produkovať viacero ID pre
rovnaký cieľ. Inými slovami, ID môžu byť nestabilné. Môže to vyplývať
z viacerých faktorov. Orientácia cieľa, hĺbka, čistota kovu, korózia,
úroveň mineralizácie pôdy atď. Dokonca aj smer pohybu cievky môže
spôsobiť, že zariadenie vygeneruje viacero ID.
V niektorých prípadoch nemusí zariadenie vygenerovať žiadne ID.
Zariadenie potrebuje od cieľa dostať silný a jasný signál, aby mohlo
poskytnúť ID. Preto nemusí byť schopné poskytnúť hodnotu ID pre
ciele v okrajových hĺbkach alebo menšie ciele, aj keď ich zariadenie
zachytí.
Majte na pamäti, že hodnoty ID cieľov sú „pravdepodobné“, inými
slovami, odhadované hodnoty a nie je možné presne poznať
vlastnosti zasypaného objektu, kým nebude vykopaný.
5) Pri použití veľkej cievky pumpujte ňou pomalšie a nedržte ju príliš
blízko zeme.
6) V niektorých prípadoch, keď je hodnota stabilizátora nastavená
vysoko, zariadenie nemusí byť schopné vykonať automatické
vyváženie zeme. Vtedy najskôr znížte hodnotu stabilizátora a po
vyvážení zeme ju prepnite späť na predchádzajúcu úroveň.
7) Ak je aktivovaná funkcia vibrácií, aj keď používate jeden z režimov
bez pohybu, kde táto funkcia nie je aktívna, zariadenie bude počas
vyvažovania zeme vibrovať, pretože sa pri vyvažovaní prepne do
režimu All Metal (všetky kovy).
