DR-4 - Most versatile mapping system

The DR-4 has proven to be the most versatile and unique multi-purpose pipeline mapping system. With a proven track record on every continent and in most pipeline segments, this multi-diameter system has easy handling features and provides the most accurate positional data location.

A unique system of exchangeable centralizing wheel-sets gives the DR-4 an operational range of ID90mm (3.5") and up. Whether the pipeline is made of steel, concrete, PE or PVC, this mapping system will improve any horizontal directional drilling (HDD) implementation procedure.

A selection of invert wheel-sets are also available to map pipes with tight access and/or lateral feeder lines.
