Underground Cable Tracing.

Zoomup

An P.V.C./P.V.C.  cable is run in steel conduit underground from a farm barn to another location. It may run underground to some nearby concrete slabs previously used as a base for wooden sheds, or it may run for about 80 metres to some distant  derelict outbuildings.

I am not too familiar with all of the types of underground cable tracers available.

Which would be the best type of cable tracer to use to determine its run? There may be other buried metal to confuse some tracers. Will a signal injected into the cable be able to be detected by a cable tracer as the cable in inside steel conduit?

The cable is currently dead.

Thanks,

Z.

    Ten parallel plastic pipes in a pit, what sort of test is that?

    A really good test of the basic claim of many dowsers, that they can detect water underground.

     The problem with a lot of tests is that there are too many variables. If someone succeeds or fails, there is always a post-hoc argument over why; e.g. “I didn't find the water but I did find X instead”, “you just got lucky”, and so on. For the parallel pipes tests, all the dowsers enrolled onto the test agreed in advance what the conditions for pass/fail were, and that it was a fair test of their abilities. All agreed in advance that given 10 parallel plastic pipes in a field, each buried about a metre down and about 3 metres apart from each other, that if water was ran through one of those pipes at random, they would be able to tell which one. Each dowser observed the pipes being buried, knew their location, and was allowed to survey/test the ground before any water had run, to rule out any anomalies.

    When the test was done, the correct pipe was identified only about 1 time in 10.

    Yes I accept that things can become magnetised. No, it think it is unlikely that magnetism is a significant underlying mechanism for dowsing.

    As a footnote, after decades of investing claims of the paranormal, james Randi said that although he encountered many charlatans, he thought that all the dowsers he met had a genuine (if mistaken) belief in their abilities.
