And a battery pack + lights, which are heavy, so that limits how far you can stick that pole...The last few hundred feet of lined cave there is incredibly tight and silty, so it'd have to be able to be pushed several hundred feet with twists, turns, ups and downs if a cave diver is going to have to manipulate it(and I suppose see whats actually going on in front of it)...
...and you'd still need a camera + housing rated for 160' that is small enough to push through the restrictions.
