Yep plenty of solutions around looking for a problem  :-)    Or perhaps
looking to create a problem.

There's definately a mindset in the rec (and tech?) community that money
and technology need to be thrown at every problem (from dealing with high
air consumption to keeping your tank from coming loose).  Rather than
attacking the underlying problem.  Don't have enough air/bottom time,
improve your air consumption.  Tank keeps coming loose, tighten it properly
before the dive.  Can't understand the tables, learn.  Dive companies,
shops, magazines, etc just pander to this and there-by promote the mindset.
 After all it's in their interest to keep reinventing the wheel.  I don't
know if this is really even a conscious thing, afterall the folks in the
industry are either subject to the same mindset or not divers at all (I
can't believe whoever sewed the pocket on the front of my wetsuit has ever
worn a wetsuit).

I had the Scubapro buckle on my old jacket style BC's (stab jackets).  I
certainly loved it at the time but there were definate problems (tricky to
adjust correctly if you needed to swap tanks between dives, the potential
to jam shut if struck hard, could entangle lines (in a location you can't
access without removing your gear, had this happen).  Definately reliable
from my experience though (never had one come loose during a dive).  

I have no complaints with the plastic cams I got with my single tank
adapter and wings.  If anything I prefer them now to the Scubapro type
mounting system.  I can adjust easily for different tank diameters and I've
never had the cams come loose on a dive or snag anything (there are two on
the STA so a backup if one did come loose).  I think the problem many
people have with tanks coming loose is due to poor technique...

1) Not tightening the cams correctly before the dive.  Unthreading the
strap from the last hole, pulling the strap tight, applying tension and
then rethreading the strap and pulling into place.

2) Leaving those stupid rubber friction pads the manufacturers put on in
place.  Often prevent the cam sitting properly making them more likely to
come open on the dive.

Having said that they are plastic and I have seen lots of broken cams.  I
saw an aluminium cam (not sure who makes them) the other day and stainless
would be more durable.  Not sure if there'd be other issues.

Cheers,

Simon
