This thing is already on the top of my "must have" list. I just wish I knew a ball park figure on it's cost so I would know how much blood I'll have to sell to pay for it.
Back in the 80's there was a wetsuit company, I think it was Moray, that made wetsuits with integrated B.C.'s built right into them. They had the bladder built into the front of the suit and had the oral inflator hose coming out on the upper left hand side of the chest. I seem to remember that this was a New Zeland company so maybe someone from that neck of the woods can back me up on it. Most of us have also seen the pictures of Pipin's and Loic's inflatable suits so it has be done in the past- although those didn't have the timing systems on them.
From the picture in the article it looks stream lined enough for spearing. The part that caught my attention was that the cylinder was a small bottle that could refilled off of a scuba tank, something like a spare air. This would be MUCH nicer to have than replaceable CO2 cartriges.
I tried to email Terry Mass on a price, or a contact, but haven't gotten an answer back.
