Gotcha! True. Might as well play with them. Sadly, by the time we ship things here and pay duty, the total cost is about 2x the cost you pay online. I saw those DGX manifolds. They're apparently on backorder until at least Jan (According to the rep). I have relatives coming here in Dec., so may...

Did not consider corrosion, but that's a good point. EVERYTHING corrodes here!

I have the twin steel 50's already here from when I came over the U.S., but they've never been dived (long story). So I'd be looking at a manifold and bands only. My SAC rate is good. I prefer one long dive over two shorter ones and on an AL 80 filled to 3200-3300, my usual shore dive is...

Thanks everyone for your input and advice.

Sorry, good point. I should have clarified. I want to make sure putting together this set of double 50's will actually be worth the difference vs diving a single AL80 (which is what I almost-always dive; I also dive CCR, but don't like to do it alone). The twin 50's will, of course, give me...

I live on a small island in the Caribbean, so getting stuff here is difficult. I want to make sure I get it right. I'm thinking of building a set of tiny doubles (Faber 50s) as I dive solo most of the time and want some redundancy and additional gas. I mainly do photography, so my diving is...

No worries. Thank for the info though!

Thanks for the info! Dive Gear Express has them all on backorder until January at least. Thermos are the only available with them currently.

Hello, I am trying to build "tiny doubles" and already have 2 Blue Steel DIN valves. I want to know if I can avoid buying an entire manifold (and just buy the cross bar instead). The vales have the following markings Blue Steel 10111 636 18-09/309 S.o.S. Thanks,

Not sure if this is the same incident (or at least one of them): Police are investigating after three men died diving from the same boat

When you say, “it took all my willpower...”, that’s exactly right. I remember it being such a mental struggle to convince myself to stay down and keep that reg in.

I found this post reply by the late TS&M and I think it’s apropos. Apparently, hyperventilating does cause a retention of CO2? The term "overbreathing your regulator" is supposed to refer to reaching a respiratory rate that the regulator simply can't provide. In practice, this is all but...

Yes, I had the pins and needles feeling running down my arms and hands, I felt hot flashes, and of course, the racing/irrational thoughts. Maybe it was hyperventilation. That brings up another question I had - I thought it was not possible to “overbreathe” a modern regulator (I was diving with...

It’s somewhat reassuring to know that even an IDC instructor gets those feelings - even if purposely induced.

Thanks all for the responses so far. I’m slightly intrigued by the science and mechanism of CO2 retention and panic now. Nitrogen narcosis is often talked about in cert classes but not CO2. Yes, I have access to lots of those easy sites thankfully. I know I need to get “back on the horse”...

I had what I would call a full blown panic attack on a dive today. I was always puzzled by a diver’s urge to spit out the reg and bolt to the surface and never thought it was possible that I would feel that way; until today. Was on a shore dive in pretty intense current today. We swam into the...

Thanks everyone for your replies.

Right. I remember checking my serial when the bulletin came out and it not being of the affected units. I guess the crux of my question is - if it’s not an affected reg but still has the ACD “feature,” any reason to worry?

I have a Legend with the ACD in the first stage. I read some reports about the ACD closing during dives, which has now led me to consider dumping the Legend and picking up a new reg. In the research I’ve done, I don’t know if it’s entirely clear that the ACD failed or there was servicer error in...
