Unknown Extremely loud sound?

[MB NZ]

Are you running environmentally sealed 1st stages and are the seals intact?

Yes and probably

I'll check when I get home. Interesting line of thought.

A stainless steel cam band buckle can make a remarkable sound. Leave it a little sideways when it's cammed over so the edge of the buckle rests on the double layer of cam band instead of the tank. Later on the dive when that edge slides off the nylon and snaps against the tank you will definitely hear it.

I had one burst and it was a pretty loud sound. Similar to an explosive diver recall device.
