Complete range of field instruments for

Gamma ray spectrometry DC resistivity & IP EM conductivity survey Magnetic susceptibility


  • Electromagnetics
    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-ray
    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.

  • Magnetic susceptibility
    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).

  • Short guides:
    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 2019 you can meet us at our booth at the following main exhibitions:
    PDAC - March 3 - 6, 2019, Toronto, Canada
    SAGEEP - March 17 - 20, 2019, Portland, Oregon, USA
    EAGE Near Surface - September 8 - 12, 2019, Haag, Netherlands

  • 1st GFI Workshop 2018
    Electromagnetic Conductivity and Earth Resistivity/IP Tomography Surveys
    We are pleased to announce that the first GFI International Workshop on Electromagnetic Conductivity and Earth Resistivity/IP Tomography Surveys was held from April 24 to April 26, 2018 in Brno, Czech Republic.

    Many thanks to all participants for visiting us, sharing experience, presenting specific work and theory, discussions, networking, and wonderful time we spent together.
