I misspelled the name of the video I was describing in the previous post. It is called "Hart Attack."
I was told that it was filmed in the cave beneath Hart Springs, shown below. http://underwaterflorida.homestead.com/files/hart.jpg The video features a diver squeezing through a tight spot with full side-mounted tanks and other gear. The passage has a beautiful flow of white sand streaming thru the squeeze. Yet the passage is not silted and the cinematography looks like it was filmed in high def. ( I can't wait to watch it on a 65 inch flat screen ) The film doesn't show how the cameraman got thru the squeeze. It appears beyond the squeeze they found a vertical underwater borehole passage. How did they light up such a big passage? The filming of this must have been rather difficult. I would presume they spent many hours filming just to get this 5 minute video. My question is, If you were a hard-core underwater cave diver, would you squeeze thru spot, not knowing if you will have room to turn around. It seems like the chances of death in that squeeze suddenly go from 75 percent to 80 percent. I would classify that as "extreme caving." I will never do that. But it is exciting to watch someone else do it, especially when it was filmed with such high quality. Has anybody out there seen this video yet, and if so, do you have any other comments to add?
