The Ditch Witch 2150GR can detect both metallic and non-metallic pipes and cables to depths of up to 19 feet (6 m), depending on soil conditions and antenna selection. And with 5.6 mph (9 km/h) survey speed—four times faster than that of competitive models—and digitally controlled radar, the 2150GR provides faster, clearer images.
2150GR provides an accurate survey whether the operator is pushing or pulling it across any surface.
User-friendly software enables the operator to manually input landmarks such as water hydrants and sewer drains, for more informative survey maps.
Multiple frequencies allow the operator to customize the unit for the job conditions.

With three modes and more than 20 frequencies, the 950R/T system helps you quickly locate buried telephone, CATV, power, gas and water lines with a tracer wire. In active mode, the 950T transmits via direct-line connection, induction clamp or induced broadcast signals. In passive mode, the 950R detects signals generated by 31 kHz (CATV) and 50/60 Hz power, as well as re-radiated radio frequencies. And in beacon mode, the 950R detects signals from optional beacons to locate non-metallic service lines; with the 512 Beacon, the 950R locates blockages within cast-iron pipe.
Lightweight 950R receiver is balanced for easy handling.
Simultaneous 8 and 29 kHz transmission means an alternate signal is available if one is hard to detect; 80 kHz is helpful in locating old tracer wires or pipes with insulators where low frequencies do not work well.
