Having done this before, I would suggest that you'll have better luck locating the lid/cap to the septic tank...
It's big metal, and won't be too far below the surface.
Just go all metal and listen to the size of the target...ignore the display...you'll know when you've found it.
(You don't need much sensitivity for this task...you're basically looking for a target not much smaller than a manhole cover, just a few inches down.)
