Hi Laura,
I bought a couple of them a while back. I love them. Do you still have any in the DIN version?
Thank you,
Jose

Yes I do. Just give me a call to order!

Who can do a rebuild on these? I have one and the rebuild kit, looks like either the IP needs adjustment or it need a rebuild (causing blowby on the second stage that doesn't stop until you are at 20 feet or so.)

Yes, I agree sounds like the IP needs adjustment. It is a relatively standard balanced diaphragm first stage... Any decent service tech should be able to work on it. Especially since there's no parts issue because you already have them.

My usual LDS says their guy isn't certified on them...I'll check around. Any service guides available?

Suggest you get the rebuild instructions from Laura. The adjustment for IP is shown in those instructions. Get yourself an IP gauge that you can plug into your BC inflator hose and you can check IP every time you dive. One of the nice things about these regs is you can easily adjust the IP without opening anything up - and you certainly don't need to be a regulator tech to make the adjustment. Just make sure you cycle the pressure to the 1st stage a number of times and check the IP after each pressure up cycle. It should lock into the setting of your choice.

You also might need to check the cracking pressure on your 2nd stage. Of course if you have breathing effort adjustment on the 2nd stage you may just need to detune it a bit.

However, actually knowing what the IP is really helps you to understand how your regs are working.

I need to get an IP gage, any good sources out there?

Mine seems to have an extra endcap with a black rubber diaphram on the end where the adjustment knob is supposed to be, I assume I just use a pin wrench to remove that endcap and diaphrapm and the adjustment knob is under there? It is not shown in the manual.

Scubatoys has one - it was hard to find on their site - easier to call. Leisure Pro also has one, but it is a little small.

See P. 33 of service manual. It is NOT a knob, but rather the cap itself which appears to have an opening for a hex key.
