It's spring, when a diver's thoughts turn to... compressor maintenance! :) I've got some questions, so I'll start separate threads for each. This one is abut changing the oil. I also have questions about filter cartridges, as well as startup/shutdown procedures. A bit about my compressor...

Hi guys, so I am starting to seriously dive in cold waters. So far I have used this setup: Mares MR22 Abyss Regulator (old Style). I went to ebay with the intention to check the market for a good second regulator set to be all set up. In the end I bought a complete Poseidon XStream set with 2...

Here is the latest on the move to refillable sorb canisters in the Poseidon. As announced a few months ago, Poseidon and Molecular have reached the decision to stop producing the prepacked scrubber canisters for the Poseidon VI and Se7en. While the prepacked canisters will continue to be...

Hi! There seem to be several threads floating around discussing whether poseidon regs are dir compliant or not. I have been diving the newer generation xstreams for some years now and it seems to me that there is very little one can say today against its dir/gue compliance. In the past people...

My question is, how does the Poseidon Xstream first stage work? What makes it different from other first stages? And what exactly is their “Thermo-Dynamic Antifreeze” (TDA) system, and how does it work? The technical info page on Poseidon’s website talks about ”through-flowing water” but I was...

Hey gang, Can anyone provide any insight or experience with the Poseidon Trident fins? Any feedback would be awesome! I can pick up a pair for a fairly decent price so I just want to know what are the pros and cons. Currently I have Aeris Accel, Atomic Blades, and Mares Volo Power. (Not sure...

Hey guys, I just picked up some used Poseidon 3960s with jetstreams. They're clean and recently serviced but one of the second stages doesn't breath quite as good as the other. Also, the IP is 150 on both (doubles set) and passed the regulator "checklist". Does anyone know a Poseidon "guy"...

I have a Parkway-Poseidon Jet Suit dry suit. I think it is from the late 70's or early 80's, but is in great shape. I don't dive in Alaska anymore. Here are some pics of it. Is it worth anything? Thanks for any help or input.

Excellent condition Poseidon Jetstream 1st and second stage regulator. The second stage is actually a sherwood ultima, which was a Jetstream made by Poseidon for Sherwood. The internals for both first (Poseidon 2960) and second are all Poseidon and have been professionally serviced and O2...
