I recently purchased the scout locator with the remote transmitter, and I got a 1/4" fiberglass rod that screws right onto the transmitter that I push in by hand. I mainly use it to locate sewer lines before we sawcut for the tie ins. My problem is with the 1/4" rod it flexes to much in a 4" and bigger line and won't make it around the 1/4 bend on 3" and smaller. What is a good cable to use to be able to push it around 1/4 bends? I do not have a camera and I don't need one at this point just want to locate where to tie in. Do they make something you can push by hand or do I need a drum type machine?
