You say this like he intended to go there, and this whole thread has debated to death the whole deep diving thing, but in reality, as is most cases, you all don't have all the facts. I personally know of two very experienced divers that were out in the exact same area, at the same time, in which this accident took place. They had to abort their dive after only a few minutes as the tide was running quite fast. For those in the area, when the tide runs this fast, the currents can actually suck you down. This seems to be only a factor in the mans death, but it would suggest an explanation as to the depth, which was recorded on a computer, not a guage.
Too often I see people blaming this or that on ideas that would seem to affirm ones own knowledge or experience. In my limited time underwater, i have come to realize that every dive is a new dive, no matter how long and hard you prepare, something will always be different, from the things you see, to how much gas you have.
Just lets try to have open minds, and learn, learn, learn, maybe not so much soap boxing and preaching. We all bring something to the table, we should also add a little respect to that.
