Poseidon jetstream drum noise

[deep-descent]

One of my Jet Streams sounds like a drum beating underwater. Breaths fine, does not leak, but none the less it is loud. Has anyone had this problem? I am obviously going to take it in for service again.

Can you tell if the sound comes from the 1st or 2nd stage?

im sure its from the second, I switched a few around.

That's a good question; I'd have to look at the stage before I'd even venture a guess.
