1st stage

I have 2 Poseidon XStream 1st stages pulled off of a Poseidon 7. So one is color coded for oxygen and the other is black. There are scratches and scuffs in the chrome, but they both function perfectly. They're pretty bomb proof. Looking to get 200 each +$10 for shipping. I'd do $350 for both...

Hi folks! What about 1st (first) stage Metal filter cleaning I heard the ideal would be to change them, but what about cleaning? And if you dont have any other solution, in the mean time your new one is on its way, how would you clean them? Thx

Hi, anybody can help me identifying that 1st stage which has been said to be model warrior and same spare parts as an apex XTX200? Thx!!

Apeks TEK3 set for doubles. USED. Look to be in near perfect condition. I bought these used as a set for the XTX50's that came with them. I'm not diving doubles yet so I'm selling these 1st stages. Figured I post here before going to Ebay. Including all the port plugs and the DIN caps. Asking...

Thinking about replacing my Apeks ds4+ with the dst for ease of hose routing. Do a significant amount of cold water diving so worried the more rotating parts, the more points of failure. Is this something I should be concerned about?

Bought this on eBay to hook up to a 1/4" npt fitting so i can run my powder coater off it without worrying about moisture from my compressor. plus i can use it to run air tools and air up tires on the boat, camping, mountain biking ect. Any idea what model it is? i don't plan on using it to dive...

Hi guys, I'm looking for the equivalent or better than a scubapro MK17/S620ti. Also if anyone has ordered this configration could they please advise how it was packaged!

My wife has a colleague that handed her his old regulator to see if we had a use for it. The setup has a US Divers "Conshelf 22" primary 2nd stage and a US Divers "Octo" safe 2nd. The 1st stage is marked US Divers on the yoke screw handle and I assume it is a variant of the Conshelf but not...

Stopped by the LDS today and was inquiring about prices on regulators that I could use on my pony bottle. The owner of the shop recommended the Aqualung Calypso as an inexpensive possibility. I responded that my wife has a Calypso reg set and it is not recommended to use when water temp is...

Hey interested in buying a ScubaPro A700 and MK17 Evo Combo that has recently been serviced (with proof of service) has had minor use and or is new. Budget is around $600 mark located in the North Seattle area for local deals if not willing to pay for shipping as well.

My dive partner yesterday reflected that I am using an older version of the Mares MR22 1st stage and was wondering if it was worth buying the new version of the MR22. Until recently I thought the only change was that they cut down the amount of metal on the outside to make it smaller/lighter...

What should one think about these pony valve 1st stage regulator combos, e.g. like these: Drysuit / Deco Bottle First Stages Or like this on the low end: Balance Piston Din First Stage Not sure there is even a manufacturer mentioned. Is that a potentially (for a travelling pony) a worth while...
