hello Curt, 'very deep' is very relative :-)
I had one implode in my back, at 115m depth, and the BANG that that gave, made my hartbeat go over 225....
first we thougth it was the housing, no, then the lamps, no, only then we discovered one of the floaters was missing.. it had 'disintegrated' completely :-) not one part of it we found back..
later we understood from the green-force company that when a hollow floating device implodes at great depth, it is crashed in all small pieces, and it drops like snow down the wall....
do I have to tell you we didn't descent another millimeter...

ps: it might be a try to fill it up with PU foam
I guess that I was thinking that "very deep" for most people shooting pictures would be around 300'. For anything deeper than that a little homework might be a wise investment.
I have had mine to over 300' and the pipe diameter is 2" Sched 40 black PVC pipe which has very thick walls. Smaller pipe will actually go deeper because of its increased strength.
Filling the pipe with foam is another great idea and would give even more strength to the pipe.
I have also heard that "bang" that you are speaking of, I had a camera housing crack on me once at 250' and it was a very disturbing noise.
It sounds like there are some other good options out there. The PVC pipe has worked well for me for my video camera and arm bouyancy.
