Can Anyone Identify these First Stages?

Because it's cheap, easy to clean but mostly because of the crappy plastic second stage that comes with it.

So, pop an Aquarius or Conshelf second stage on it and go diving!

I was using the SEA this weekend and it is a nice breathing reg. Thanks guys, I'll take a look at the manuals.

FYI, 99% of how well a reg breaths depends on the second stage and the reg tech, the first stage has little to do with it.

I agree. I was just being a bit facetious with my posts. I have dived balanced diaphragm and unbalanced piston first stages and have been satisfied with both. I am not happy, however, with plastic second stages and prefer to use a properly tuned all metal second stage such as the USD seconds from the 1970s. They are simple, rugged and easy to service and tune. My youngest son currently dives a new Calypso first stage with a second stage from an Aquarius. He tried the plastic Titan/Calypso second that came with it but didn't like it as much as the Aquarius second.

That would be an old black and chrome Sea4
