Hello Timothy,

The can in the corner is a Geodevice broadband 40 to .05 Hz.  The PVC
thing in the foreground is a "Dave Nelson" invention being tested and
it compares very well. No moving parts except the "water" in the
thing.

Take a look at these two traces.  Which are filtered 5 seconds to 1
Hz.

One is the commercial BB and the other is the PVC "FMES".

I'll bet your next question is "What is under the black insulation?"

Not much.  Dave is working up a more detailed write up but he hates to
type.
