    Default Weapon of choice for Utilities 20 to 30 feet deep?

    When you have to locate something that deep what locator do you choose without a doubt?

    Odds are pretty good. The locator version of the excavator's "I thought it was deeper" is "I did not think they were digging that deep".

    I saw a duct bank hit at 24'.

    The ViVax VlocPro at 5 watts, there is a 10 watt version, works very well at that depth. You can push the output up on the transmitter and adjust the gain on the receiver.

    The ony problem they have is poor construction and breakdowns requiring repairs are too frequent. Would be a good light duty machine.

    Hey yaherdme22 - Welcome to the Cable Vine! My experiences on 20 to 30 feet deep utilities:

    CATV feeders, trunks & fibers - Telephone copper cables & fibers - Radio Detection 8000 with two watts of f8 power.

    AT&T conduit packages (coupled) - Electric conduit packages (coupled) - Tracer wires on plastic gas mains and plastic water mains - Radio Detection 8000 with two watts of f33 or f65 power. I'd bump it up to five watts if there is nothing else close.

    Electric single, two phase and three phase (direct connect) - Radio Detection 8000 with five watts of f8 power.

    Steel reinforced concrete water mains (direct connect) - Steel gas mains - Radio Detection 8000 with five watts of f33 or f65 power.

    Ductile water mains - All above utilities that will not carry the Radio Detection 8000 in f8, f33 or f65 frequencies - Direct connection and/or induction mode using McLaughlin Verifier G2 digital utility locator in f80.

    If the McLaughlin Verifier does not work (it has not failed me yet), I would fire an e-mail to my first line supervisor explaining my predicament. After my e-mail is sent, I would lay paint using my last piece of locating equipment in my truck, my witching sticks.

    Metrotech 9890XT will locate utilities as deep as 25', we located a fiber duct at 35' with our i5000. It's all about the power output of the transmitter, a proper connection to the utility and proper grounding.

    Wing, we are liking our Verifier G2's as well. A great tool on tough water mains.

    We have a Storm Line crossing one of our runways at 58' deep =)

    Fortunately we have a tracerwire on it...... Still looking for something to send a signal that deep.

    The only thing I know of that will find it at that depth is a track hoe.

    My suggestion, not knowing your equipment options:

    Direct Connect and turn your most powerful transmitter to it highest power setting, low frequency of course.
    Make sure your trace wire is grounded at the far end.
    Sweep slowly across the approximate area and cross your fingers.
    If it doesn't come up, you may just be out of luck.

    You may need a more powerful transmitter.

    Racked my brain and came up with a last desperate try if nothing else works.

    You have a storm drainage line and tracer wire buried with it. At the open ends snake a second tracer wire through the drain. Perhaps a shielded wire so the signal will transmit out from the conventional tracer only. At one end connect the two wires together. At the other end connect one transmitter lead to the regular tracer and the other transmitter lead to the second wire. You now have a closed loop which should limit bleed off while making a very strong signal from the conventinal tracer.

    If that does not work the track hoe finds them everytime.

    Thanks for the advice guys, fortunately this line is out in the back 40 and there isn't much going on back there to the depth that thing is living. She's actually a pressure line filled with diluted deicing chemicals. So there is no way to get another wire through it, or putting a sonde through it. I don't even believe the tracer wire is intact. They had some issues pulling the pipe back through the bore. I was just spewing out that lines can be down pretty freakin deep.

    Once had a locate where they were setting 100 ft poles near an intecoastal waterway. I had an electric duct running UNDER the water. The prints showed the bottom of the water was at 65 ft, and the duct system was 6 to 10 ft under that. Needless to say, I could only get about 40 ft from my access point 300 to 400 ft away from the edge. My last reading was 31 ft. RD8000 direct connected to the ground strap, and even tried clamping to get anything more. Too deep, too deep!

    What I did in the past on a gas main at 25' was to simply be onsite when they start digging. After digging down halfway start painting.
