Transmitter Powered Pushrod with 260' (80m) cable 

FlexiTrace can be used to find and trace small-diameter, plastic pipes. With Flexitrace, the entire length of the cable can be detected from above ground using a Schonstedt Pipe & Cable Locator, such as Rex or u-LOCATE. The rod, similar to a sonde, at the end of the cable can be energized  as well and inserted into pipes as small as 1/2" (12mm).
