The most troublesome issues I see in the video is the women who is steadily loosing her tank, but nobody is paying attention. She was obviously way out of her comfort zone, simply by the fact that she is clutching the computer and watching the information is taking up 90% of her band width.
If the tank popped out and pulled the reg from her mouth there would have almost certainly been a life threatening panic attack. That was more concerning to me than needlessly kicking up silt and trying to bury the computer in the sand in order to record the maximum depth possible.
I think that someone has to volunteer to cut a preview or do a highlights edit, so that we don't all have to watch all 16 minutes!
