You have no clue about the "facts". Diving to 80m+ is no big deal now. Hundreds of random amateur tech divers do that every weekend as a casual hobby. They typically own their own gear (not rental), which can purchased new for about $30K including training. The equipment such as a closed-circuit rebreather (CCR) and drysuit is somewhat specialized but widely available on the open market from numerous manufacturers. I know a number of divers living in that region who have done much more complex and challenging dives, although obtaining and using the explosives is a separate issue.

Hard, but doable. Here is the analysis by an experience diver.

Right, Achim Schlöffel is legitimate. In terms of complex tech diving he has been there and done that, and has the pictures to prove it. When he says something can be done there's no reason to doubt him.
