This is probably old news to most of you, but I just found out about it.
There is a standard for how waterproof your gadgets are. It is called IPX and ranges from 1 to 8 IPX-8 appears to be the rating you would want for caving gear where you plan to go to caves like Honeycreek. Here is the IPX list: http://www.e-headlamps.com/ipx_waterproof_standard.asp You may see this listed on things like GPS units. On a related note, GPS units have come along way in the past year. I think one model lets you show your digital camera photos, and also has an MP3 player. I want a GPS unit that works underground, so that I don't get lost. Also it needs to show a vertical profile of the cave, so I know what level I am at. They had that in the movie "The Cave," didn't they? or am I confused with some other sci-fi show?
