Too far, too fast. Another diver in a long list that has "fallen" to the age old mistake.
Gauge says 4300 PSI??? That's what I call Doin' It Right!
You guys have got this all wrong! That unit is designed to be pulled not pushed! This is another example of inadequate training most likely caused by the zero to hero approach. Sufficient time pulling at each level before proceeding on to the the next training level would have provided him with enough experience to self correct his oversight!
The problem was he was not using expensive Equipment with a blue H( help symbol) on it that is what caused the accident.
The hardwear attachments failed in this case. Switching to stainless would prevent this. From the picture the bracket looks like brass or god forbid nickel plated, which is contraindicated for technical diving. You're trying to solve a problem that shouldn't exist
He's lucky the attachment failed before it killed him. The attachment was done metal-to-metal without a severable link. Had he become entrapped, he would not have been able to cut the equipment away. In the future, that wheelbarrow needs to be assembled using a few loops of cave line at all attachment points.
The last thing I ever want to do is hurt you. But it's definitely on the list.
