The MAGNA-SYGG from S.U.N. Engineering, Inc. is truly a non-intrusive pipeline pig detector. Simple and rugged, it can be strapped to the surface of a pipe or it can be used as a portable pig passage indicator. You do not have to shut down the pipeline and wait for an expensive crew to install special fittings - the MAGNA-SYGG pig detector is ready to go to work.
