INTRODUCTION
What is the hodograph and why is it so important? The received signal is characterized
not only by its amplitude and phase, but it is also a vector quantity. Amplitude and phase
depend on the electro physical parameters of objects such as conductivity, magnetic
permeability, depth, geometry, etc.
In order to accurately describe the nature of the received signal from an object is very
difficult, given the variety of influencing factors. However, it is possible to point out some
general patterns. Earlier, we mentioned that the signal is a vector quantity characterized
by amplitude and phase. If you hold any metal object to the coil it is evident that the
magnitude of this vector will vary. The end of the vector will describe, on a coordinate
plane, some shapes (lines, loops, etc.). These shapes are called Hodographs. The latter
most closely describes the complex interactions of the coil with metal objects.
When analyzing the hodographs remember a few general rules:
• Hodographs of small and medium-sized ferromagnetic objects are in the left quadrant
(i.e. have a negative vector angle);
• Hodographs of objects of non-ferrous metals and large ferromagnetic objects lie in the
right quadrant (positive vector angle);
• The larger the area of the surface of an object the higher the electrical conductivity,
hence the greater the slope of the hodograph to the right;
• Travel times of medium and large ferrous objects, as a rule, have the shape of a loop;
• Hodographs of non-ferrous metal objects are mainly straight;
• A properly ground balanced unit will have a vector along the horizontal axis. Examples
of the hodographs of some objects are shown in Fig. 14. Thus, analyzing the shape and
position of the hodograph, along the coordinate plane, there can be a certain degree of
probability as to the identity of the object type.
Examples some objects are resulted in a Fig. 1:
Fig. 1
It should be noted that the hodograph examples given are idealized and do not take into
account the effect ground mineralization.

In actual practice the shape of the graph will be defined as the vector sum of signals from
the ground and detected object. For example, a coin taking into account the influence of
ground minerals can look as follows (a Fig. 2):
Fig. 2
The stronger the ground minerals the greater the affect and deformation it will have on the
targets signal and shape on the Hodograph (loops verses a straight line or arrow)

STARTING UP THE DEVICE
Prior to turning on your detector please read the instructions thoroughly. Upon
every startup of the detector there is a calibration of the detector in air.
It is necessary for fine tuning of electronic parameters to the surrounding environment.
Therefore it is crucial to perform the following on every startup:
Hold the device firmly in your hand and if possible use the supplied armstrap to
steady the device
Lift the coil to waist level;
Be sure you are clear of any large metal objects within 6 feet;
Turn the power switch [ON].
Upon powering up on the display there will be information regarding the currently
installed coil, quantity of available calibrated coils, the version and date of the
software, and as the help on functions of buttons in the inclusion menu (a Fig. 8):

REPEAT COMPENSATION
Fig. 10
In this case switch off the device and repeat coil compensation in a different place
(Having previously determined the absence of any metal objects). If compensation still does
not occur, after insuring there is no presence of large metal objects, check to make sure the
coil connector is seated correctly and the proper coil is installed. If this has been verified
and compensation is still not established the device will need to be returned to the service
center.
Device power off is carried out by pressing the power switch to the down or off
position.
Once the switch has been turned off the device may take up to 10 seconds to
completely shut down as settings are stored into the internal memory.

GROUND BALANCING
Proper ground balancing is necessary in order to reduce the effects of ground
minerals on the detector. Without proper ground balance the detector cannot operate
to its full potential and can be subject to false signal from ground minerals.
To carry out a proper ground balance perform the following procedures:
1. Locate an area of ground that is free from any metal targets within a 4 foot diameter.
Use standard search mode with no discrimination to help locate clean ground;
2. Lift the coil to around waist level and
3. Press the button [GB]. The device will enter the automatic ground balance mode
( Fig. 15):

On bottom left - Ground balancing mode (A - Automatic, Р-Manual).
4. Slowly and smoothly lower the coil to the ground avoiding touching grass,
stones, etc. Lower the coil at a speed of 1 to 2 seconds from the raised to
lowered position.
Upon lowering the coil to the ground, on the display, will appear a line in the
screen left-hand side (a Fig. 16). Lower the coil until the line reaches the display
left edge.

5. At successful balancing, the device will play a melody
6. Press the button [GB] for transition to standard search mode;
7. If ground balance was not successful raise the coil waste high and wait 2-3 seconds
( ground line will retract to a small circle in center of screen). Repeat steps 4-6.
To enter the manual ground balance mode press either the + or - buttons. This
will allow you to adjust the ground balance point achieved in the automatic ground
balance procedure. The automatic GB procedure will be turned off and parameter
SPEED AGB will now be set to OFF. To return to previously set Speed AGB values
either perform automatic ground balance procedure again or simply access Speed AGB

in Search menu and set to preferred value (p. 28).
If, after carrying out the ground balance procedure, the value of БГ differs greatly
from zero this may can cause an incorrect installation of the phase parameter of the coil.
To reset this value to zero simply press the button.
ADJUSTING THE KEY PARAMETERS
Access to the key parameters is carried out from the main search mode by simply
pressing the button. Once pressed, in the bottom left corner of the display, will appear
the parameter and its related value as seen in fig 17 (gain:15)

Fig. 17
With each subsequent pressing of the button there is a transition from
one parameter to another. Changing the value of a parameter is carried out
by using Keys [-] and [+].To decrease the value of the parameter setting press [-] and to
increase its value press [+] . If, after approx. 15 seconds, there are no further changes
made the key parameter settings will disappear and return to the normal search screen. The
last adjusted parameter is stored in memory and by pressing the + or –button will recall
this last adjusted and its value will change according to whether you pressed the + or-
button. Note that this quick access is only available if the detector does not have the
discriminator training mode enabled. If the discriminator training mode (teach mode) has
been enabled than the + and –buttons perform different functions when pressed in standard
search mode ( no key parameters displayed). In order to access the key parameters one will
have to press the button to first access the key parameters then make the appropriate
+ or - corrections
Adjustment key parameters concern:
CC –Current to the coil,
АT –Audio Threshold,
IT –Identification Threshold,
GN –Gain (Sensitivity),
RS –Recovery Speed
Further details on each of these parameters are now considered. The range of each
parameters settings are within the square brackets []
16

17
COIL CURRENT (CC) [1- 2] Sets the level of current supplied to the coil. At
A setting of 2 (TURBO) maximum current is applied to the coil. Maximum depth
ability is achieved however operating time is decreased due to increased battery
usage. At the minimum setting of 1 maximum battery time is achieved at the cost of
reduced depth.
The remark. If operating near sources of electrical interference or other detectors
it is advised to set CC to 2 (turbo) and reduce sensitivity in order to reduce these
affects. On the other hand it may be necessary to reduce CC to 1 in order to
minimize the interference on other devices close by.
RECOVERY SPEED (RS) [1- 9] defines speed of the automatic tuning under
ground conditions in the dynamic mode (This setting has no affect in the pinpoint
or static mode). Reducing the speed of auto will increase the depth of search.
However in areas of considerable ground mineralization, target ID reliability can
worsen. There can be false responses from the ground, and also separation of the
closely spaced targets worsens. Lower settings of the recovery speed are
recommended for areas with deep targets, areas with low mineralization and areas
with little metal trash. It is also important to use a slower steady sweep speed
avoiding erratic movements, jerking etc. as well as keeping the coil parallel to the
ground. Increase in recovery speed settings is recommended for areas with many
closely spaced targets where target separation is most important. It is not
recommended to set the RS below 5.
AUDIO THRESHOLD (AT) [0- 20] defines the minimum signal level required to
generate an audio response on a detected object. Reducing the Audio Threshold
setting increases the sensitivity to small and deep targets but also increases the risk
of false audio responses. The device will react to the smallest particles of metal as
well as possible ground mineral concentrations. To achieve maximum depth of
search set the Audio Threshold as low as possible without creating excessive false
responses from the ground. Increasing the Audio Threshold will improve the
comfort of search by reducing false ground responses but at the expense of
reducing depth sensitivity. Unless there is a special reason to do so, do not set
the level too high as a loss in response sensitivity to large nonferrous items can
occur.
GAIN (GN)[0- 20] Defines overall sensitivity of the metal detector. The higher the
Gain the deeper the ability of the detector as well as increased response from smaller
targets. To achieve maximum depth and target response set the gain as high as
possible while still maintaining a stable detector. In areas of excessive ground
minerals or areas with a lot of metal trash it will be necessary to reduce gain levels
to a lower level. It is not recommended to set the gain to the maximum level
especially in areas with mineralization as performance will decrease at these
excessive settings. In most cases a maximum setting of 16 is recommended to avoid
false responses.
IDENTIFICATION THRESHOLD (IT) [0- 20] Defines the minimum signal level
required to generate a target ID audio response as well as to display a VDI value. If
a target is detected but does not meet the minimum signal level an audio
response from the threshold will be heard but no VDI number will be displayed.
Lower values will increase the depth response for target ID but reliability as well
1
7

18
as stability of the VDI will worsen. At increased settings depth of target ID will be
reduced but VDI reliability and stability will increase. At a setting of 0 the device will
identify a target immediately but on deep or weak targets the probability of error greatly
increases.
ADDITIONAL PARAMETERS
Access to additional parameters is carried out by means of the branched menu. All
parameters are grouped in a separate submenu. Access is possible both from the main menu
and by means of fast access by long pressing of the corresponding buttons in normal search
mode.

such as the pressing of keys, successful ground balance, the melody played upon
successful coil compensation etc.
KEYS SOUND [ON/OFF] Enables or disables sounds made while pressing any
keys (buttons).
Border Fe - [-85 to +85] Defines the VDI border for setting the iron tone. The user
may find this advantageous as the effects of ground minerals can affect the signal
from small non ferrous objects causing them to respond with a negative VDI number.
Thus the user may choose to set the Fe border to a specific negative value to include
these small low conductive targets. Also one may wish to include some small
desirable ferrous objects by adjusting the FE border to exclude these from the Fe
tone. While conversely one may wish to set this value to a slightly positive value
[+10] to include small annoying pieces of foil commonly found in modern sites littered
with trash. Setting is done on a personal preference of the user.
The NUMBER of TONES[1F, 2F, 3F, 10F, 91F] Allows the user to set the number
of available tones .
 VALUE 1F- will generate a single tone on ALL targets including ferrous
targets. NOTE: a setting of 1F effectively negates the Border FE setting as
there is no separate FE tone
 VALUE 2F- A low tone will be generated for ferrous targets while a
high tone will be generated for all non ferrous targets. The border for
these tones can be set under BORDER FE option previously mentioned.
 VALUE 3F , A low tone will be generated for small ferrous objects
whose border has been determined by setting BORDER FE. A medium
tone will be generated for targets just above the Border FE setting but
below VDI +15. A High tone will be generated for targets within VDI +15
to +90 range.
