Soap bubble testing is not what I am after. I am wondering if anybody has
a recommendation for a reliable and sensitive gas detector. A divining rod
to find buried pipe is really not what I am looking for either.

A bubble test IS the standard. (NOT soap though)

Unless you're going to calibrate your tester regularly, and is part of
what you do for a living, bubbles are the way to go.
The "electronic" gets pulled out if don't want bubble juice
dripping all over the place, or other mitigating factors are in place.

The electronic is very good, but really is a go/no-go tool.
It won't tell concentration levels of the leak you have, and that isn't
even necessary to know with regards to common domestic pipe work.

If I have to win a wager to find a leak, (say one pica-bubble every 20
secondsg)
I'm using bubbles. HTH.
