Thank you for the replies. I did over simplify, and I think I know where the error was in the process. The diver and gear would displace a specific volume, at a given total weight, and that would be used (if going that route) to determine the weight needed to counteract the difference.
However, my initial calculation was only looking at the portion that would have been above the surface without the extra weight, as the rest would have been submerged, whatever portion that would be.
When looking at the diver (and gear) as a whole, then the difference in densities of the two types of water make the larger difference as mentioned by other posters.
Does that sound right?
