I was installing a line to a new roots type blower that unloads dry mix at a concrete plant, the owner said there was a 2" water line near where I had to bury my conduit. He whips out a "Witching stick" and proceeded to "Witch" we're the water line was. I don't know if he was close, but I did not hit the water line.:lol:
dowsing.
it works for some people, not for others.
i'll do it with two pieces of #6 solid copper wire.... just for grins.
sometimes the results are surprising, but i wouldn't throw down
chalk and get the backhoe out based on it.
i had a journeyman who did it, and was pretty good at it.
dunno how or why... we both tried it, and i'd be hit or miss,
and he'd be pretty close... pretty close is a couple feet,
4 out of 5 times.
there is no scientific support that it's better than chance.
then again, there is no scientific basis that you can walk
barefoot on 700 degree burning coals without getting the
crap burned out of you, and i've done that.
but i wasn't dowsing when i was doing it...
i think the whole trick, is to find someone who can really
do it, and let them.
