Wow what a weekend, This was a very challenging course to say the very least. I have a whole new respect for cave divers after this course and a new outlook on how I will be diving from now on. It made me look at gear differently as well. I actually lost over 12 pounds during the course. So at the very least it is great for weight loss. Not my gut but the amount of weight I dive with. I enjoyed Ginnie Springs and was impressed by the visibility there. The spring flows out at 35 million gallons per day so clear water seems to constantly be coming. Peacock Springs is pretty clear unless you are doing a bunch of line drills blacked out and are new to caves. The bottom will kick up quickly until you get the buoyancy down really well. This course will teach you how to do that. My Mares Dragon BC malfunctioned and dropped weights so I did some hang time on the ceiling. It showed me that recreational equipment does not belong in a technical environment. The most important thing to know is never go anywhere you don’t have training to go. You cannot dive a cave or overhead without training. A cavern course is a nice way to learn some new techniques and get a taste of caves to see if this is what you might want to pursue. I still remain undecided myself and will continue to ponder it for a while.
