Hello,

I’ve have a Poseidon Besea W100 with a 12L steel twinset. Had this wing for 15 years. I haven’t used it for 18 month and was setting it up. Inflated it and left it to sit as a test. Good thing I did because in 10 min the bladder leaked along the seam. So I wrote to Poseidon asking to buy a new badder. But alas they no longer make the W100 bladders. They now have the One Wing 50 and say that the badder from that wing will not fit into the W100. Although Poseidon say that the One Wing 50 is not rated for a 12L twinset I think there is plenty of lift in the wing. But I really don’t want to drop €400 on a brand new wing when all I need is a new bladder. I have seen a youtube video of a guy in South Africa who made a new bladder for the W100 by gluing PVC sheets but I don’t feel brave enough to trust that.

So my question to the members here. Would anyone know if there is somewhere to get a new W100 bladder or if they have any experience of fitting a bladder from another manufacturer. And in that same vain does anyone have experience of using a One Wing 50 bladder, which seems to be the same as Besea W50, even have the same part number, bladder, into the W100 shroud.

In essence I’m seeking advise how to keep using my perfectly good Besea W100. Apart from making my own bladder.

Thank you all in advance.
 
I am also curious about this 12L twin issue (when using the W50 variant) because I have been made aware alot of people do/have dived 12L twins... Even the person who I got mine (Beasea W50) from did as shown in the photos.

When doing a lift calculation the math seems to work. Are Poseidon just being very cautious as historically bladders used to be far over sized for lift?

Maybe they just didn't get it certified for 12L twin at the time and haven't put it through testing again for a new cert.

It's and old design now the Beasea range and been replaced by the One harness and wing but notably the W50 survived essentially and was just renamed. The bladders, hoses dump valves etc are all the name including the part numbers.
