The Electric Listening Stick FSB-8D is necessary to use FSJ-1. The FSB-8D Leak Survey Tool is a "Rod based" accoustic listening instrument for listening for water leaks at meters, valves and hydtrants.
The Fuji Sound level measure FSJ-1 records noise levels from the FSB-8D to judge if the pipe has a leak or not.
