Utilizing CDI's popular portable receiver design, the CD42-MSTS may be used to locate and track any type of pig: foam, uni-cast or metal-bodied, even ILI tools along the ocean bottom.

A series of bright LED's give the operator a clear indication of transmitter strength whether the transmitter is passing the receiver or an ROV is searching for a stationary or stuck pig. Safe, simple and reliable.
