Drilling test holes for depth confirmation

RE: Drilling test holes for depth confirmation
I wish I knew how to answer that.

Same discussion brought up on this here thread

Although it did get a little off-track (for once not my fault JD Smile )

I don't think that the proximity of a narrow test hole to the probe location will be a big deal - but I have no scientific evidence to back that.

That said, I just did a test in a school where I hit re-bar three times before I finally got a successful probe hole. I will patch the dud holes up with some portland cement mix, but obviously not until after the readings are taken. I'm a little paranoid that the water in the patching mix will show up somewhere nearby...again, probably nothing scientific to back that but you can't be too careful.
