Yeah I absolutely understand that. But that wireless part id what gets me man. Why add so many points of failure? I’m just so mind blown that they were okay with using such off the shelf components.

I’ve watched the Deep sea challenge documentary maybe 6-7 years ago… and IIRC everything on that sub had to be rigorously tested and custom made. They made sure that the sub was prepared for the worst. They reduced the no of failure points as much as they could. “Always assume anything or everything that can go wrong, will go wrong” was kind of their philosophy.

So I always assumed that, every other sub and expedition will be treated the same. It’s like sending astronauts to the moon.
