Dadvocate regarding the redundant systems. I agree if you are diving caves, penetration, deep technical stuff it is a must but with good well maintained equipment on dives that seldom go below 30m it may be a bit of overkill. Of course an occy is always a given. We are so lucky here in Sydney most of our dives are shore dives. When we are going away equipment is double checked and needs evaluated based on types of dives anticipated.
Boy do I agree with those who say people are too quick to sue! What is to be gained? Money? Is that all life is about?
I remember a terrible accident I attended as a Paramedic. Young people doing silly things in cars

The driver of one car 22 and his sister 16 were dead. The driver of the other car 21 and best friends all his life with the ones that died.

What I saw that night was hard for me to look at as an experienced Paramedic. The surviving driver had sat with his dead friends waiting for help and I KNOW those awful images and his role will haunt him for life! He was so traumatized I had trouble getting him to move or focus.

It was tragic! What purpose did it serve for the parents to sue that young man? Financial ruin on top of the emotional one.... didn't bring the dead back....the dead driver was just as responsible
What does attacking the instructor do? Do you honestly think the instructor (who taught both of them) hasn't second guessed himself, isn't horrified that two people he taught are involved in an incident like this? We are effected by the death of this young lady how much more so will he be?
When I first started teaching first aid I had people come into my class for recertification and I remember thinking.... "What idiot gave these people certificates in the past?" because their skill level was so low. Three years later I realized I was the last "idiot". No matter how good you are, no matter how hard you try to make it otherwise people may meet the reasonable standards and you have to pass them. If they don't use or review the skills they lose them. That is out of the instructor's hands. I can't, nor can my agency control the attitudes, experiences and reactions of those we train.
I feel privledged to be able to get up in the morning and teach a life skill. I have had students come back and tell me they have saved lives because of what I taught them. I wouldn't want some of you in my classes because I would have to quit doing a job I love for fear of losing my home if you stuffed up!
