Scraper (1) for determining the position of pipelines (4) with at least one scraper body (11, 21) and on the outer circumference of the latter are provided support elements (12, 12', 13, 14, 14', 22, 22', 23, 24, 25, 25', 26, 26') for guiding in the pipeline (4), the scraper body (11, 21) containing a gyroscopic platform, as well. as supply and processing means fo r measured results, characterized in that the scraper body (11, 21) is guidable by a combination of support elements (12, 12', 13, 14, 14', 22, 22' , 23, 24, 25, 25', 26, 26'), under a defined, constant angle with respect to the pipe guidance axis (R), whereof a first part (13, 14, 14', 24, 25, 25') is radially rigid and a second part (12, 12', 22, 22', 23, 26, 26') is radially resilient.
