2. Introduction
Introduction about COBRA GX 8000
Based on “changing the concept of technology in the world” principle, it was imperative to work hard and
develop years of expertise and experiences in the field of metal detectors.
The main objective was to develop a product that meets the highest quality standards so this product has to be
the top in detectors technology to stop years of faults in this field.
Cobra products were developed by Geo Ground, the leading German company in geophysical measurement
and underground detection technologies with a clear goal of accessing this technology to all prospectors, by
developing easy-to-use technologies at an affordable price for all prospectors and those looking to reach their
golden dreams.

metals, hunting treasures and excavation of archaeological treasures.
This device meets the professional prospectors' needs who search for treasures and the professional prospec-
tors all over the world.
COBRA GX 8000 includes for the first time in one device for detecting metals, six search systems accompanied
with various detecting technologies which offer all the tools and functions needed by professional prospectors
and beginners for different applications and tasks related to search activities for treasures and metals detec-
tion.

The frequency generator is planted on the ground at
an unspecified point inside the search area and the
main unit is connected to the frequency generator.
The search antennas are fully opened and the
antennas is oriented perpendicular to the ground
and in contact with the soil for 15 seconds.
Next, the user person heads towards the south line
and waits for two minutes for the search antennas to
pick up the target signals and head towards it.
When the search antennas are moving toward the
target, the user starts moving in its direction.
Track the antenna movement, when the antennas
reach the buried target field, the state of the anten-
nas change into crossing state X shape.
User determine the two antennas intersection
point by marking a straight line on the ground
The user should search from the other three
directions North-East-West and repeat the same
steps
After the four directions intersecting lines are
determined by the user in the ground, the depth is
calculated by using the following method

The user must cross the flat lines on the ground to form a specific area.
As a result of the intersection of the area diameters, the center of the
area is determined to the user.
The user starts to measure the depth from the area center straight
to one of the diameters of this area.
The user does not have to track the antenna movement in this case but
adheres to the straight movement.
After reaching a certain distance, the antennas will go oppositely. At this
point the user will mark a line on the ground and the distance between
this line and the center of the area will be the depth of the target.
The distance traveled along the diameter direction is same as the target's depth
Example: If the distance is between the center and the antenna intersection point
3 meters, this shows that the target depth is also 3 meters.

It is recommended for the user to measure the depth from two different
diameters for accuracy.
