To make a drill bit that’s long enough and thin enough for discreet probes, take a stiff wire (insulation props are perfect), cut one end on a bias, chuck it in your drill, and go. I’ve gotten through walls and even floors with this; I have even gone around corners.

what is an insulation prop?
It's a wire you put between I-joists, or nominal floor joists to hold up batt style insulation. They make them the appropriate length for 16" and 24" OC.
ok, thanks.
Or you can use the wire that holds up political signs- there'll be a lot of that available in a few days.
I always carry wire coat hangers with me. They make great probe drill bits,can bend them to make paint can hooks,paint stirrers,hammer holsters,etc. As versatile as duct tape...lol.
