The RIDGID NaviTrack line locator has been introduced by Ridge Tool Co. NaviTrack features a large, real-time, liquid-crystal mapping display that guides operators to the exact location of the target, regardless of how the unit is held. The new RIDGID/Kollmann line locator quickly pinpoints the precise location and depth of a transmitter in buried pipes and drains. It also locates underground cast iron pipes, water lines, electrical lines, telephone lines and other metallic cables when they are energized. NaviTrack operates in three modes. The search mode uses gauges and audio signals to guide the user to the target. The map mode locates the transmitter and maps the direction of the pipe. The trace mode locates energized lines and power lines. Ridge Tool Co.
