Acoustic and Seismoacoustic Profile Recorders

The Seismoacoustic source of "Bumer" type is designed for works with application of high power and has an additional benefit — change of frequency of a signal due to change of energy of a source of CSP-D. It allows to achieve increase of width of an impulse of a signal not available earlier. The increase of width of an impulse provides more big penetration with quality preservation of a single impulse.

Geotechnical Equipment

Geotechnical equipment used by geotechnical engineers to study the structure and shape of earth materials. With our equipment geotechnical engineers perform tasks, trying to determine a safe and practical solution

Drilling Rig

The rig is designed for different research works and drilling operations. It is used for core drilling and drilling of wells on water. Core drilling of high accuracy is provided by use of the fixed kinematic mechanism with a mast of wide section, complete with system of pressing/extraction by means of cylinder with effort of extraction to 100kN
