We are talking total darkness here, a two day exposure would still show nothing, you must use a flash. I have bought a Pentax 400FTZ flash secondhand but have not tried it in the caves yet, it has a spot beam but is proobably only good to about 3-4 metres or so. I tried it from about 15-20metres and it seemed pretty good used on a tree though.
Only two things are infinite, the universe and human stupidity, and I'm
not sure about the former.
