Here are some websites I found about mapping caves, one even has some free software for it as well.

I like the suggestion of the camera on a pole to check out any areas before you totally commit and enter. One idea would be to use some sort of extendable painters pole. It can collapse down to a smaller size, extend out further than a regular tool handle and is made of lightweight aluminum or fiberglass. May cost ya $20 or so if you don't already have one. I would also consider taking a firearm with you. I know it's wet and damp but a pistol could come in handy if a cornered or territorial animal is in there or comes calling. Shot gun would be best but hard to maneuver in there I'm sure. Maybe a Taurus Judge (.45/.410) or even a .45/.410 2 shot derringer. Just make sure to keep the dog at home! Good luck man! Can't wait to see more pictures!
I'm not really a techno guy...Not a problem! Glad I can help! Yeah you got me by 2 years but at 56 I'd still stand side by side with you carrying a big stick and a trash can lid to help you fight off that big bad bobcat. Lol!

Great post......I want to see the treasure you find. My son had a friend (both military men) show him a cave in Kentucky that was on his aunt's homesite. Near a stream, and they could see Indian sign.
And, as he told me, there was a ledge up above where he could reach, and something on the ledge. He never went back, as the aunt didn't want anyone on the site. I still wonder what the devil was on that ledge. That is what keeps us in the hills/caves, swinging our machines. We are adventurers. Thanks for a great story. Would love to share one like it, from Korea, but any cave here has snakes.
I don't like snakes. 'nuff said.
You'll be 1st right after me. You'll probably hear me all the way to Korea if we do find something of value. Odds are against us... but like all of us adventurers know... we just gotta know. The best part is being able to share the adventure with everyone. But I learned my lesson last Saturday... it's a 2 man job. No snake problem here... I mean in cave. It's too damp and cold. But we DO have snakes buddy.
