The ‘BOBs’ were on that dragon den show where the mad designer wanted a piles of cash to fund a huge robot fish tank, they thought he was a nutter so did I, also had them for hire in Tenerife but the water was rather chilly to tempt herself
looks like a disaster waiting to happen, what happens when you smash into the coral! 
Just the thing for Morecambe bay on a Christmas afternoon.
Iirc (and someone ought to confirm or otherwise) but does this not do away with the need to decompress. Can't remember the exact reason - but to
do with helmet and nor having mix pumped into lungs?

I would think it unlikely that those units would be able to go very deep. I would think that they would be fitted with a small tank, if memory serves probably 60 cu ft, which is the size that doesn't allow you enough time on the bottom to need to decompress. It's the time element that dictastes decompression. The only thing that you would need to do, is surface no quicker than your smallest air bubbles. Cheers Ray
