    They won't dig without locating the power lines first. They just wanted to know if "live" wires can be found w/o special equipment. Like with a metal detector. Otherwise they will hire a locate company.

    A 501 using the inductive clamp always worked great for me.

    hook onto ground and follow usually works for me.

    This would be my route also. I think the pro 800 from armada has this option also. That said you know what your listening for, average homeowner wouldn't. As its been said the equipment is only as good as the person running it.

    I don't think so, if it does there must be a way to use a 521 with an inductive clamp.

    It has wireless mode so it doesn't necessarily need the clamp kinda like a 501. And the pro 800 and 521 are different animals. The pro 700 would be comparable to a 521. Greenlee doesn't have a comparable model to the pro 800.

    Maybe you're right but I find it strange that a clamp isn't included or even an option.

    hiring a professional locator is like buying an insurance policy, sometimes it's a life insurance policy, sometimes not.

    240vac is just 2-120vac legs at 50/60 hertz, nothing special to locating it.

    i would attach to the ground and follow it, the only issue is that you can't identify the target but, the owner knows what it services so you know where you should end up at.

    the inductive clamp will work for the 501, same as the pro-800 using its wireless broadcast mode. i actually like and use the broadcast mode on mine a lot. i also use the tr-4110 and the inductive clamp from my dynatel a bunch too.

    metal detectors won't locate power (they detect ferromagnetic fields and not electromagnetic fields)

    there were a lot of right and a few wrong replies to this thread but, a few years ago the wrong would have out numbered the right. you guys did good :)

    'bout time :laugh:
