    Default Radiodétection and rebars

    Trying to locate fiber optic in pvc conduit in 12'' thick wall but its full of rebars like not ordinary since fiber optic is not conductive i take a electrician fish wire and weld a 14 ga electrique wire to the end loop and pass it in the pvc tubing all the way and then hook up the aligator clip to the end of wire and the other to the fish to make a loop ; i tried all the frequence on my tx 3 and seme like the signal transfers in the reebars

    It is possible that the receiver is picking up both signals on the loop and does not know which signal to read. I would try and build circuit with the wire from the fish tape put to its own ground. There by building a locate circuit with proper current flow. If that does't work then if you have access to the other end of the run ground the Fish tape there without the wire and build your circuit that way. Good Luck

    Greetings KILMAR! Welcome to The Cable Vine! Oh, how I LOVE your city! It is a beautiful town full of life!

    I visited Montreal about 10 years ago and left wishing I could stay. Your city has 4 universities (2 English speaking only and 2 French speaking only) and I stayed 2 nights in a hotel off one of the English speaking campuses. All I can say is, "WoW!" If I was a single man in my twenties, Montreal would be my Heaven..........

    The Montreal women are Gorgeous/Magnifique! Imagine, generations of the Limeys inter-breeding with the French producing some of the hottest Meufs on earth:

    Even the Montreal skanks are HOTT! But I digress............

    For me, the best way to trace out the path on dielectric (sheathless) fiber is using a steel fish tape. I don't mess around trying to ground the end of the steel tape to make a closed loop. I snake the steel tape into the conduit, clip onto the tape and start using the inductive frequency f8. If the signal is weak, I move up to the next higher inductive frequency. I will continue the process until I get a believable tone. Dry conduits, conduits full of water or conduits surrounded by rebar-reinforced concrete, using only 2 watts of f8 directly on the steel tape has been successful for me. Good Luck! Luv Ya Man! And I Luv your City!
