FIELD: geophysics.
SUBSTANCE: device has depth and tension detectors and magnetic marks. Tension detector is made in form of beam with tension converters, on which by cheeks three circling rollers are mounted asymmetrically, one of which is a measuring one. On cheeks of one of rollers magnetic marks detector is mounted. One of cheeks holding bolts of said roller is used for adjustment with possible setting of it into position, appropriate for cable diameter, and has eccentric cams, allowing to change position of roller axis in vertical plane during replacement of cable. In cheeks of this circling roller apertures are made for eccentric cams of adjusting bolt.
EFFECT: higher precision, better consumer qualities and lower laboriousness of maintenance.
