GENERAL INFORMATION
Metal detector BERKUT 5 is designed to search for and identify metal objects in the dielectric
(dry sand, wood, etc.) and low conducting media (soil, brick walls, etc.).
Some applications of use are:
•Criminal;
•Engineering;
•Housing and community services, construction and fire-fighters to search for underground
utilities, pipelines, cables, manhole wells etc.
• Archaeology and treasure search.
The device is designed to operate under the following conditions:
-Ambient temperature from -20 up to +50°c (-4 to 122 F);
-Relative humidity up to 98 per cent at temperature of 25°c (77 F);
-Atmospheric pressure from 630 to 800 mm Hg.

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)
ASSEMBLING YOUR BERKUT 5
Remove the detector from the box. When shipped the detector and parts should
look like Fig. 3.
Fig. 3
Assemble the Detector. For this purpose:
Remove the detector rod from the box;
Remove the electronic control box from the shipping box;
Install control box on upper portion of the rod by sliding onto the installed tab;
Install supplied coil on the lower rod. Tighten coil bolts snug. Do not over tighten;
Wrap the coil wire around the rod insuring the wire does not hang lose. Loose coil
wires may cause false responses.
Connect the coil to the socket on the rear of the control housing.
Remove battery compartment cover and install batteries;
Close back cover.

ATTENTION! DO not over tighten the plastic locking collars on the rod as well as the plastic
Coil bolt.
Once assembled your detector should look like Fig. 4.
