Wouldn't it be great if you had a 'mass' checker for low conductive hits?

[Mike Hillis]

Just thinking some thoughts. High frequency units hit low conductive trash so hard that the trash looks good. Wouldn't it be nice if when you hit that good sounding low conductive trash, you could ping it with a lower frequency and check the mass? For example...Foil paper screams at high frequency but goes invisible at lower frequencies.

Probably could be a way to compare signal strengths at a low and high frequency and come up with a "mass index" of some type to help sort by density. And once you had that in play, then you could also discriminate by density. You could discriminate by phase and by density indexes.

That would be way cool. Especially if you could identify density ratios for thin wall can slaw.

Yeah...that would be way cool. Modern trash is changing, we'll have to change our discrimination features to keep up with it. Discrimination by Density Indexes sounds like a modern solution to me.

Whites Spectra V3I lets you see how strong each frequency hits a target. It's OK, but still has its limitations.
