Anyone know of a cheap supplier of CO2 cartridge re-fills for Aquatec junior
auto SMB's. Cartridges are 16g threaded 3/8 UNF.

which size is that?

I've seen the ones for the JR signal marker (little yellow one) as
cartridges for little air dusters for computers

12oz from http://www.boysstuff.co.uk/product.asp?id=134910 +2 free for 9.95
I have no idea if that is a good price or not

Go down to your local halfords, they stock them. Or from just searching
online I see two for £4.99, think that's about the standard price for
threaded ones:

Try giving Kent Tooling Products a ring. I seem to remember that when chatting
with them at the dive show that they were knocking them out for £1.00 each.

Hope that helps

Not totally on the same point, but why do they have CO2 cartridges, and why
are they bought over air ones, considering the problem and cost in getting
them filled / replaced after every dive where you use your DSMB?

Most people use the CO2 cartridge SMB's for emergency only.
For this purpose they're ideal as
- they're a lot smaller than the ones with 0.1L bottles
- you always know the bottle's full.

Ahhh - that makes sense then. :O)

I didn't follow this thread from the beginning, so forgive me if my question
has already been addressed. On my side of the Atlantic, CO2 cartridges are
small, sealed bottles, usually with a screw thread on the neck, but with no
valve or opening. They are activated by a pin that punctures the seal,
allowing the CO2 to escape rather quickly. They are not refillable. Is
this not the case in the UK?

Yes, sounds the same. You pull a cord on the SMB, which presumably
causes the cartridge to be punctured, and the gas then fills the SMB.
