The RIDGID NaviTrack Line Transmitter is the ideal solution for tracing buried cable, TV lines, phone lines and other metallic lines that carry an electromagnetic signal. With up to 10 watts of power output, the transmitter pairs well with NaviTrack II and NaviTrack Scout locators, and it has adjustable frequencies, including 128 Hz, 1 kHz, 8 kHz, 33 kHz, 200 kHz, and 262 kHz. A sturdy conductive ground rod with molded grip stores conveniently in the case, while two 25-foot coiled connectors allow for reaching distant connection points. A carrying strap allows for easy transport and for more complicated line sweeping. In addition, an optional inductive signal clamp pairs with the transmitter to make it easy to apply signals to lines with inaccessible conductors. 800-769-7743; www.ridgid.com.
