The terminology in this exchange distinguishes direct sweeping from standing back while other systems go forward. Stand-off operation aims to keep the parent vessel as far from the minefield as practicable. A Kingston-class example raises concern about operating close to mines, followed by an audience comment about degaussing equipment being fitted for but not installed. The operational point is the value of distance between the crewed vessel and the mine threat.
