Trust me there is no water in that area deeper than 30', and that would be via setting your computer at the bottom. I'm assuming they were at the freshwater spring since thats about the only reasonable place to dive in the area, in which case it is more like 20'. It gets shallow in all directions and land is 100' away or less pretty much wherever you go. That's the reason this is so 'wtf'; by the time you surface in that area you can handle just about any situation or draw the necessary attention to yourself. Any boat with a tower should have easily been able to spot him even if he was gone for 5 minutes and there was a current.
