Bill,?
I don¡¯t know all of the in¡¯s and out¡¯s of your layout. ?NCE has an article on their website that discusses a BD20 detection challenge that reads similar to yours at this link,?. Hope this helps. ?

I've tried a variety of "winding" strategies, but without
success.? When I talked with NCE's technical support fellow the
other day, he was pretty skeptical about the feasibility of 25'
blocks.? He suggested that the only viable option was installing a
POT on the BD20, which I haven't yet attempted.? In the meantime,
I'm double-checking all my wiring.? My experience (successfully)
building a test-bed tells me that it's all too easy to goober up
connections.

Hi Bill,
If you haven't tried it already, try putting more than one turn
through your BD20.? Literally just loop it around and go through
it again.? This increases sensitivity of the BD20.? I don't think
you need multiple detectors in a block.? Check the BD20
instructions for multiple turns through it.
