| LOCATION, LOCATION, LOCATION. The three modes and
20 frequencies of the 950R/T system help you quickly locate buried
telephone, CATV , power, gas and water lines: Active — 950T and 970T
transmit via direct line connection, induction clamp or induced
broadcast signals; simultaneous 8 and 29 kHz transmission makes an
alternate signal available if one is hard to detect, while higher
frequencies help locate metallic lines with insulators that weaken or
block low frequencies; Passive — 950R detects signals generated by 31
kHz (CATV) and 50/60 Hz power, as well as re-radiated radio frequencies;
Beacon — 950R detects signals from optional beacons to locate
non-metallic service lines; with the 512 beacon, the 950R locates
blockages within cast-iron pipe. |
