Nothing. Most recompression chambers do dry try dives where you can experience what it's like to go to pressure and then decompress. In those it is more exciting than underwater because your voice changes and the temperature changes. Underwater, nothing changes. Deco is not the fun part of diving, that's for sure - especially not extended deco like this. It's literally just waiting as he says.

Ambient Pressure. They make Inspirations and provided the breathing system for the Mariana'a Trench expedition. All made in-house. Very impressive for such a tiny little town in the English countryside.

I'm a bit biased because I work very close to AP Diving and know most of the guys there :)
