For answering g1138, my Origin Sport was new when I bought it, and the replacement was also new. The shop was in Egypt. The 3rd time, I went in France, and they gave me the Rover BCD in replacement.
I was not throwing it in a pile when coming back on the boat, I was rinsing it even 2 times a day for the 2nd one. The 1st last around 6 month, and the 2nd... 6 weeks. Find it hard to believe or not, that's what happened
. At the time, I think I posted on SB about this problem.
I used it a bit in pool, but principally in the sea.
Here in the Maldives, I dive with a shorty 3mm, and use 2 to 4 kg of weight (2-3 for me, 1 or 2 I can give to guests)... less than 20lbs for sure (if I'm correct, it's around 9kg? if it is, it would be HUGE for here).
Thank you victorzamora, now I know how to say it in english
Thank you also to the others that gave some ideas, I will look for some info about these BCDs. And if anybody has some other suggestions, keep posting
