Difference between Apeks T and TX regs?

Tricky · December 8th, 2005, 12:22 PM

Can anyone tell me the difference between the Apexs T 2nds (e.g. T50D) and the TX 2nds?

Should have Google this before posting the question...

Apparently the TX range has a heat exchanger that is not present in the T range.

and the difference between TX and ATX range is that the ATX's are amaller and more compact.

And the ATX doesn't have the nice bubble dispersion that the TX does with the wide exhaust tee.

Kinda.

It's true that the exhaust tee is much larger on the TX than the ATX series, but only along the BOTTOM of the tee, where it's pointless anyway. Along the TOP of the tee, where the bubbles are actually deflected, the TX and the ATX series are pretty much the same size. Maybe the TX exits the bubbles slightly further BACK than the ATX, but we're really splitting hairs here.

Anyway, if you're in proper DIR form, you should see no significant difference. In fact, the ATX seems to be favored by some because it seems less obtrusive as a backup - smaller overall while it hangs around the neck.

Yup, I have both and honestly cannot tell which I am breathing at any particular point (TX on singles, ATX on doubles) except the mouthpiece on the ATX seems a bit longer so i can kind of feel it on the roof of my mouth more.

Glad to see you around SeaJay, reading your DIR-F post on that other website was what first got me interested in DIR.

I agree that the better your trim is the less it might matter, but there are times where perfect trim isn't always possible (for me anyway). I can definitely tell the difference in the amount of bubbles I do or don't see, but I think that's more due to how far back it sweeps vs. the ATX.

I've also been told that the TX breathes a little better but I've tried both at 90 ft and I couldn't tell any difference.

I almost posted in my original reply that were I to do it all over again I'd still get a TX50 primary but would definitely opt for the ATX50/ATX40 backup (vs the TX40 I have now) just for the reason that its less bulky under the chin. But then you get into a situation where the rebuild kits, etc. don't match and that's a whole 'nother slippery slope.

Hey, how cool is that? Great that my DIR-F report had enough effect to get you curious.

I wonder if the great Admin Gods will let me post that here, too? It certainly does seem pertinent.

Thanks for the welcome. I sure am glad to be here. Seems like a truly great forum.

I don't own any TX series regs, but I've dived with them in the past... You've got a great point. Like others here, I couldn't tell a difference, but it makes sense that in some positions you could. Maybe the original poster will be able to make up his/her mind based on those pictures - which were really hard to come by at the time.

Here's something to even further cloud the issue... The ATX series and the TX series service kits are the same kit. I believe the two regs share many of the same non-replacable components, in fact... So really, I think that the only real difference is the size and shape of the diaphragms and the exhaust tee.

...Which, of course, means that no matter what's picked, you're compatible with other Apeks owners... Hence, very DIR.

...Doesn't it make you wonder, then, when the magazines tout the latest Apeks reg as, "better than the old model?" Yeah, the truth comes out...

Tricky · December 8th, 2005, 10:59 PM

Most of my regs are Scubapro (Mk20s and G250s), but I have recently bought some TX40s having tried my buddy's - I prefer the way they sit against my chin. Anyway, my question was due to the fact that I'm watching a T50D on eBay and wondered how it's different to my TX40s. I reckon that if I buy the T50D, I can either keep it as is, and just dive with it, or I may be able to stip it down and turn one of the TX40s in to a TX50...
