Measuring instrument MARY (Multifunctional receiver for electrical and electromagnetic prospecting) represents the newest development in the field of creation of the portable geophysical equipment. Compactness and simplicity of use of the device are combined with opportunities which until recently were inherent in only large-sized electroprospecting stations. The Scope of a measuring instrument includes structural, mapping, exploration, hydro-geological, engineering-geological, archeological, geotechnical and ecological researches.

Multichannel electroporspecting receiver IMVP is used to make researches by induced polarization method (IP) in frequency and/or temporary domain, direct current (impedance) method (resistance method), frequency sounding method and differential-normed electroprospecting method.

Switching module COMx64 is specially designed to be used with compact multifunctional EM receiver MARY-24 for shallow resistivity imaging. This module features an internal switching board for 64 potential electrodes. Four strings of cable with 16 electrode take-out each are connected to switching module. System is designed for surveys with Pole-Dipole Array. One electrode is moved manually. Lightweight, rugged, high accuracy multifunctional EM receiver MARY-24 with switching module COMx64 is ideal affordable instrument for archeological, geological mapping and civil engineering applications. Surveys can be performed very efficiently with only two (2) field operators.

The ACF-4M equipment is intended for carrying out audiomagnetotelluric and frequency soundings using natural and controlled sources electromagnetic fields.

Controlled source radiomagnetotellurics (RMT-CS) is intended for application of the RMT technique in remote regions where there are no possibilities to measure enough radio-transmitter’s signals to provide the standard RMT measurements in frequency range 10-1000 kHz and work is usually fulfilled in the frequency range 10-30 kHz in the VLF profiling mode. Using of controlled source (generator and grounded cable) allow us to realize work in the sounding mode. Because the lower frequency limit is downed from 10 kHz in the standard RMT method to 1 kHz the investigation depth in the RMT-CS method reaches up to approximately 100 m for sedimentary sections (three times more than in the standard RMT method). CSRMT measurements results are presented as apparent resistivity and impedance phase curves used for the inversion procedures and obtaining of geoelectric sections.

RMT-F equipment is intended for radiomagnetotelluric soundings using electromagnetic fields of remote radio transmitters. On data of measurements of horizontal and mutually-orthogonal component of electrical and magnetic fields curves of apparent resistivity and impedance phase are calculated, which are used for inversion and plotting of geoelectric cross section.

RMT-M equipment is intended for mobile (using car or off-road vehicle for on shore conditions and boat on water areas) radiomagnetotelluric (RMT) soundings method using electromagnetic fields of remote radio transmitters. On data of measurements of horizontal and mutually-orthogonal component of electrical and magnetic fields curves of apparent resistivity and impedance phase are calculated, which are used for inversion and plotting of geoelectric cross section.
