Also, when choosing a dive shop, please ask them about their safety protocols in case something goes wrong. Does their staff have adequate training in first aid, CPR etc.? Is the shop affiliated with a decompression chamber?
Do you get into the water via giant stride or back roll? Personally, I think the back roll is more dangerous, especially for newbies. You have the potential of hitting your head on your tank valve and that can cause problems under pressure. Also, what is their evacuation procedure. These are questions that people don't consider until it's too late. Oh, another one, do they carry oxygen on board, has the staff be instructed and certified in using oxygen.
