Hello
is there any difference between the TX50 and the TX100 in breathing performance? Which one is better? Other things that should be aware of?
thanks, xerxes
I sure can't tell the difference in breathing performance. I have all three first stages. My favorite is the DS4 because:
It doesn't have a turret
Uses all standard ports
Great track record among other technical divers
Cheaper than the others
But is there any significant difference in ease of breathing and Cold water specifications? And which one is easier for doubles ATX100 or the DS4?

No distinguishable difference in cold water performance. Theoretically, the slightly bigger heat exchanger in the TX100 should make it a better cold water reg, but I don't buy it. I just went diving today again with my TX50/DS4 in 34F water -- no problem. The TX100 has done fine in cold water too.
The TX100 first stages definately route a bit better for doubles. Unfortunately, unless you use argon exclusively, you're stuck dealing with the 1/2" port on the left post. I chose to go with DS4's for everything (back gas, stages, deco bottles, argon) as a matter of familiarity and interchangability. Maybe someday, I'll pick up a set of TX100 firsts for my doubles -- who knows, I like my DS4's.
I, too, believe the ATX200's first stage is mostly hype. The ATX50 is virtually identical to the ATX200 second stage (again the heat exchanger is supposedly bigger in the 200
). I'll see (not soon enough) if the ATX50 is significantly smaller/lighter.
Regardless which second stage you choose, I'm sure you'll be very happy with it. As for first stages, I would recommend the DS4.
Take care.
