Multidepth conductivity meters CMD-E and CMD-ME have created new world standards for shallow EM survey. They
allow the calibrated evaluation of depth conductivity gradient in one measuring pass. We have increased our
production capacity so their current delivery time is under two weeks.
GAMMA SURVEYOR VARIO - 2048-channel geophysical gamma-ray spectrometer - has been launched.
However, the classic Gamma Surveyor and Gamma Surveyor II models remain available with usual support and prices to meet demand of the customers appreciating
them for many years.
We have introduced our new magnetic susceptibility meter Multi Kappa that allows depth graded field
survey suitable for archaelogical and geological studies. Measured values in the range from
10-6 to 1 are calibrated in SI units.
Resistivity and IP
To meet the requirements of our clients, we have extended the selection of multielectrode cables (see section
Resistivity and IP – Recommended sets). Passive and active cables are offered in a range of complete sets based
on powerful ARES and ARES II units, all at a significant price reduction. The sets with short delivery time are
suitable for a wide spectrum of tasks (from common single channel survey to large 10-channel, water, borehole
and other special surveys).
We recommend to pay attention to our methodical guides for electromagnetic conductivity survey
as well as for resistivity and IP imaging. Those brochures contain both theoretical introduction and many typical examples of applications.
The new edition of electromagnetic conductivity survey methodical guide is completed by rather complex physical
theory useful both for academic sphere and for skilled users. You can find this chapter at the end of the brochure.
In the year 2018 you can meet us at our booth at the following main exhibitions:

SAGEEP - March 25 - 29, 2018, Nashville, Tennessee, USA
EAGE Near Surface - September 9 - 12, 2018, Porto, Portugal
