FIELD: geophysics.
SUBSTANCE: device has beam with tension converters, on which by cheeks three circling rollers are asymmetrically mounted, depth detectors and magnetic marks detectors, and synchronizer of detectors movement with alternation of cable position in vertical and horizontal planes, having tractions. One of circling rollers is connected to depth detector and is the measuring one. To cheeks of roller, in plane, passing through its axis, at level of cable axis passing, tractions of synchronizer are fixed in such a way, that cable movement axis coincided with tractions axis.
EFFECT: higher precision and trustworthiness of measurements.
