Yeah, that's what I meant but couldn't type. LOLNo, I think it's possible that it would show the lack of separation. If it alerts in relatively the same place then there may be a course issue. Conversely, if it alerts at a shorter distance and does show separation, then the course is more useful.

When I go out with a half dozen detectors it's so hard to find a course that doesn't impact reception at some point for a least a couple of them.
Flat ground is a great start and then add attenuation from there.
Damn hilly ground is a pain....
