Yes!! Congrats Bob!! You win!!

And yes, Jim that will work as well as the footage calculation. :-)

Actually I have used the tone generator that way as well, sometimes
not very successful.  Don't know why??

I also have a rigged siren driver hanging in the van for some of those
lost wire things.  As a matter of fact I got it out last weekend to help
trace a drain pipe in my basement. I was going to push a wire down the
pipe with a flex rod to determine which way the pipe ran under the
concrete floor.  Turns out some plumber had stuck about 8" of caulk
down the pipe to seal it off from sewer gas about 40 years ago.

Ended up cutting the pipe off about 10" from the floor and was able
to dig about 90% of it out.  What a PITA!!  Could then see down the
pipe to the 90 and see the direction it was going.  Didn't need the
siren driver rig, so it back in the van waiting for it's next job.

It seems to me that I built the rig after reading about the usage
possibilities either here on ASA or some other forum.  After reading
I think it was assembled the next day and officially used about
a week later.

Really can't say if it was a previous (years ago...) typing by you Jim!!

Either way, always good reading and input!!
