Look at the field of the stake in that diagram. Now replace the stake with a small nail, something that will put out a much smaller/weaker magnetic field. Seems to me that the field would not be large enough to effect both sensors in such a case.

At any rate, I agree that the sensors could be built into or onto the detector rod. We need to run this by Eric Foster over on his PI Classroom Forum, or better yet, invite him over here (already have welcomed him here) for a look see. He had ideas along these very lines in the past, and might either poke holes in our ideas or show their merit based on his past experimentations.
