Hello,
I'm interested in getting an Atomic 2nd stage. I already have a T3 1st and 2nd. Specifically looking for a 2nd stage to go on my necklace but don't want one of the octo 2nds that come in yellow.

I'm looking at the ST1, B2, T3, T2X. My understanding is that these specific 2nd stages are essentially all identical but I'm told they vary in pricing so I don't understand why there would be any cost difference.

I appreciate your help.

Thank you!
 
You are correct those second stages are the same mechanically and materially. The only real difference is the bling (and the cost associated with it). The main price difference is going to come from the swivel hose stainless vs titanium. Which is not needed for a backup.

My advise - buy a basic Z2 second stage. While you do not state it, the "octo" versions come with a 36" hose whereas a standard second stage comes with a 32" hose. The latter is preferable on a necklace.

PS welcome to da board.

Thank you so much for the warm welcome and great advice!

I already have a nice length miflex hose that I'll swap into a new second stage. Although getting a Z series for the necklace was the same logical conclusion I came too also. It's definitely more cost effective since you're not paying for the additional swivel. I kind of want to go with one of the second stages that's all titanium inside just so that both seconds are consistent. I know there probably isn't going to be much if anyof a practical difference though. I'm hoping to maybe find a nice deal somewhere on a used atomic second stage so that I can justify the expense to myself lol!
