This video was just published (less than an hour ago):
I knew about UTD, I just wasn't aware of their solution of fitting sidemount into DIR philosophy. Or rather 'force' it in.
I can get the standardization of procedures and all (the goal), but adding extra elements (a manifold block, a tonne of connections) - doesn't that add quite a few potential failure points as well? Even in the new set-up they propose. I am not at all an expert. But compared to 'non-DIR' sidemount diving, this UTD approach seems to overcomplicate things rather than simplify stuff...
Don’t even go there…
