Multiple active frequencies allow the user to accurately locate with a minimum of interference while maintaining the ability to continue locating past faults and around conduit bends. Passive frequencies identify “live” and charged lines by their naturally occurring electromagnetic fields. The SnapTRACK® offers multiple passive frequencies — 50Hz, 60Hz, Radio Frequency, Cathodic Protection Rectifier & CATV — allowing line locating without the use of a transmitter.
Operating on active frequencies of 33kHz, 512Hz, 640Hz, 815Hz or 8kHz Rycom Instruments® Sondes are pushed into non-pressurized conduits and pipes until they reach the point of pinch or blockage. Traceable 25 feet in the air and 10 feet in cast iron, the SnapTRACK® receiver will identify the precise location of the line blockage.
