The 8880-DFF cable, pipe and directional fault finder offers utility locators three active frequencies — 815 Hz, 8 kHz, and 82 kHz, designed to ensure that adequate signal is applied to buried utilities in any environment. Multiple active frequencies allow the user to accurately locate with a minimum of “ghosting” to adjacent lines 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 8880-DFF offers one passive frequency — 50/60 cycles — designed to allow line locating without the use of a transmitter. Represented by TPSC.
