I'd just like to correct Madmole's perception that the PRISM would be locked in by the Navy so that modifications/improvements could not be made - that's not so.
The Navy PRISM version is called the Invader. The PRISM Topaz that is offered to recreational users certainly won't be locked in. The big advantage is that all the testing and ruggedisation done for the navy has enhanced the PRISM extensively. The Topaz and the Invader are indentical in their breathing loop and performance.
As for modifications - the rig doesn't need a lot of after market add on's because most features are ingreated into the unit. There is also flexibilty in the design to allow the user to configure it to suit their needs - whether that means putting different cylinder sizes on to meet airline weights or extended dives, stainless steel back plates or personal preference wings/bladders.
As for the length of the dives, lots of PRISM divers are doing 2 and 3 hour dives, a five hour duration scrubber merely means you don't have to change the scrubber on a rolling boat when your out for the day diving. Also, as the scrubber is a basket inserted into the housing as opposed to the housing been the holder, users can get extra scrubber baskets and have them pre-packed for boat trips.
