This is not directed at this specific incident, but at several similar incidents I've read over recently. They all have deep dives on air with single tanks in common:
Just because you CAN do something doesn't mean that you SHOULD. Is there something at 200ft that's not at 100? If there is, is it worth seeing more than once?
Then do it right. Get the proper training, carry redundant gear, learn the risks, and then do the dive.
In sounds like that in this particular situation it was a possibility to meet hammerhead at about 60m (200ft) and Neptune at 100m (300ft)
