I was thinking of both factors actually, just a general concern.It seems that Dave Karoly's suggestion of a 20' distance may be most reasonable... 12'...

I believe that would be true for the horizontal circle, but I was thinking specifically about the vertical circle.

We use these and we use a drill as you describe to mark a precise point. Works well for us.

Thanks Gents!
