Thanks for your inputs guys, so far it look like a 10:1 ratio between, BCD and the SCUBA equipment ( hoses and regulators ).
The reason I asked this question, that in the different interventions about bad events that can happen while diving is that they mention more the Free flowing of the regulator event and less the BCD problem, with this thread so far it shows all the contrary.
Whem I rented equipment I noticed once that the inflator bottom was not moving freely and you can feel the sand in between the push bottom and the housing where it slide, I didn't even bothered to put it on the tank and requested another BCD and told the owners the problem I noticed.
Sand seems to be the most common problem with BCD's right ?
A little of topic here
I'm showly buying my dive gear, only remaining items are, the BCD, pony thank with regulator, knife and torch, I got me a set of new Aqua-Lung, Titan LX and Octo regulator, but they still packed in my duffle bag here in Afghanistan once I return home ( hopefuly alive ) I will test them, I was honestly expecting something more rugged but the TiTan seems a little cheepo quality build, but more likely I'm under the wrong impression, I choose Aqua-Lung because they had been around for years since the beggining and heard good comments of their products, I did buy the Titan because I dive in the caribbean and not in cold waters, will this regulator be good for future tec diving ?, I know they are not good for the high %O2 decompresion tanks, but will they work properly at more depth and trimex ??, or this is just a recreational level regulator ?
Thanks for you comments, keep posting your equipment failures
