I borrowed a Scuba Pro jacket BC for the first few dives I did after open waters, I loved it. It gave me a feeling of being wraped up, I felt safe. However, as I grew into diving I grew out of jacket BCs. They are restrictive, there's not enough lift capability, nor enough area to mount extra gear. You could mount doubles to one I suppose, but, I prefer a unit made for the task of humping doubles and all the extras, a BP and wing. There's alot of weight when you deal with doubles diving. I prefer to leave my home shop fixes on land and not test their metal with my hard earned money or my life! For those of you who go with a Jacket and doubles, hey, what ever. I had a friend who was on a jury. The case revolved around a guy who modified a hand gun that was used on a home intruder. The point of the whole thing was it, the hand gun, he changed the grips, was changed from it's origionaly intended design. The lawyer was trying to persuade the jury to think of him, the home owner, in an irresponsible light for making the modification. Which in turn cast dought on his common sense and state of mind with respect to shooting this home invader and trying to inflict as much dammage as possible. Sounds wild dosen't it. People are sueing over hot coffee. If you lent out your modified BC and someone was hurt or killed, the manufacturer is now off the hook, you have a new shiney hook in your mouth. Where's Lawman when you need a lawyer!
