 Geophysical locator survey with probes

GEO EXAMINER analyses digital the signal from pairs of transmitting and receiving probes continuously. Working with probes is like “X-raying”, the soil between the probes is scanned by the induced signal completely, and all structures laying in become visible.

The EXAMINER probe signal is ELECTRICAL and it has a direct connection to the ground through the probes, the ELECTRICAL signal travels through minerals and wet ground without loosing its penetration ability.

Ground radars ( GPR ) and VLF systems use ELECTROMAGNETIC signal, the ELECTROMAGNETIC waves are transmitted aerial towards the ground, minerals and wet ground often absorb them and the depth is reduced significantly. The EXAMINER ELECTRICAL signal encounters ground resistance and takes the path of least resistance to travel from transmitters to receivers.

Precious metals in the ground due to their conductivity create LOW electrical resistance and attract the EXAMINER signal.
At the opposite a voids due to the air trapped inside creates HIGH electrical resistance.

Therefore voids, caves have a high Soil Data profile while metals indicate low. Conventional instruments on the market use only one transmitter and receiver, but the EXAMINER is on a league of its own! Its twin transmitter / receiver will push the signal at even greater depths than single ones, also detects small changes in ground geology, the result is accuracy, better depth, more resolution
from underground.

The EXAMINER is adjustable to all ground types, canceling out errors from minerals and wet ground. Also the signal has 8 gain levels to select the suitable for every area.


22 Probes

Select “22 Probe” and click on “START X 10”, underground data are automatically collected and viewed, from 2 multi-cable strings of 17 meters and 11 electrodes each. This is a great advantage over conventional geophysical systems on the market that use only 4 electrodes which make the field work time consuming - with poor images.

The multi rod data acquisition is found on geophysical locators that retail twice the cost! Storing of values, co-ordinate field settings and target imaging are operated by the locator.

The automatic EXAMINER data collection speeds up the scan,
which also will be enhanced with detailed imaging ! For 22 probe survey the “22 Probe module” is needed, along with the 2 multi cables shown.


4 Probes

Α conventional 4 electrode survey using 4 x 10 meter cables,
the operator moves manually the transmitting and receiving probe pairs, controlling data capture. A useful mode for limited spaces, target pinpointing or where finer surveys are in demand.
