ScubaPro Regulator ID

[Resqdivemedic]

Not sure if this is where I should post this but looking to ID this ScubaPro reg. I think it is an R109. My FD was tossing it out so I snagged it. Possibly going to upgrade and restore it if possible. Thanks in advance.

looks like a 109. If you have a balanced first stage, there shouldn't be much of a need to upgrade unless you have a burning desire. @DA Aquamaster can help you with anything you need on that regulator

Thanks Tbone, I'll have to see if the first stage is still around.

It is either a 109 (unbalanced) or a 156 (balanced). The internals (poppet/spring/balance chamber would tell the tale)

doesn't matter if it is or not, it can go on any first stage. It may struggle on Poseidon first stages due to the either high or low IP depending on the model, but any "normal" regulator it will be able to go on with no issues. No reason it can't replace a primary or secondary you use now. It's the same internals as a G250/260, just an old case design

109 duro-poppet:

156 s-wing (modern):

156 (earlier):

With that particular adjustment knob and rubber purge cover it is probably a Balanced Adjustable, as the Adjustable was out of production by the time those particular design changes were made.

Performance wise, it's right up there with a G250 or the current G260, just without the adjustable flow vane in the mouthpiece.

BTW - nice find!

Here is a photo of the internal parts.

156 (balanced adjustable). Poppet is not servicible, so it either needs to go back to a 109 or use the s-wing. Some switch easily and some don't.
