Our sales representative for United States of America - THG Geophysics Ltd. - published on their YouTube channel series of videos regarding the use of our instruments. We encourage you to check them:
Smartphone applications for LG-1 gravity meter and MK magnetic susceptibility meter are available
New probe in our CMD family: CMD-Explorer 6L
We have just introduced our new high resolution probe CMD-Explorer 6L. It enhances the capability of the
standard CMD-Explorer by extended depth range (0.45 - 6.3 m) and higher depth resolution (6 receivers).
Precise electronic design with stable calibration provides data for multi-layer
conductivity and inphase mapping as well as for inversion of measured conductivity sections.
CMD-Explorer 6L is useful for fast and accurate contactless investigations of buried structures and
objects in the frame of geological, geotechnical, military and other surveys.
2020: 20th anniversary of GF Instruments
At the beginning of September 2019 we have added the new product to our instrument group:
Land gravity meter LG-1 Galielo.
It is equipped with a lightweight, quartz-core based sensor, detachable control unit and advanced
technology of signal processing. The new instrument is ready to match all needs of up-to-date field gravity survey.
Multi-depth conductivity meters CMD-E, CMD-ME and CMD-ME 6L have created new world standards for shallow EM survey.
They allow the calibrated evaluation of depth conductivity gradient in one measuring pass. All CMDs are
now delivered with the new control unit equipped with two Bluetooth channels, GPS receiver and B/W or colour
display. Smartphone application and comfortable harness for side and front carrying are also available.
GAMMA SURVEYOR VARIO - 2048-channel geophysical gamma-ray spectrometer - quickly became a popular survey tool.
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.
The magnetic susceptibility meter Multi Kappa allows depth graded field survey suitable for archaeological and geological
studies. Measured values in the range from 10-6 to 1 are calibrated in SI units. Multi Kappa and the small, handheld SM-20
form a set suitable both for surface and deeper magnetic susceptibility surveys.
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.
Exhibitions and GFI Workshop:
We have decided not to participate in the exhibitions until the worldwide covid situation and related continuously changing travel rules stabilize.
Then we also would like to continue the started tradition of popular International GFI workshops. You will be informed as soon as this happens.
