If prettiness is one reason behind desiring the Poseidon BeSea, a word of caution. Buddy had BeSea W50 last season. Actually three of them before finally giving up. Handsome looks were the first ones lost because after a couple of dives lettering and logos started coming off, and BC started looking like an old rag with glue stains. All her diving was done in fresh water and gear rinsed (gently without detergents) and dried out of sun after every dive but this went on and on with every replacement too (from different batches). I have since heard a good amount of BeSeas have been returned/swapped for same reason but many have been saved the problem too. Might be model specific too, and might have been corrected by now. It was no issue returning it, Poseidon took the BC back knowing the problem.
Even though prettiness was not the main reason to give up on this fine-functioning BC, she decided to let go because all the hassle (and she took a liking to my BP/W
). The BC handled fine in water and especially above, and what comes to the extra buoyancy, I can comment on my experience. At that time I dove TransPac and Oxycheck 45lbs SS wing. I needed to add 2lbs of extra when diving the BeSea with otherwise same setup. I had reserved way more but it was not that bad.
