I wasn't talking about first aid, first aid never even crossed my mind. I was refering to experience in general. Experience being years of diving experience, in the type diving I'm seaking training for and being able to use that experience to teach scuba to me. A certification doesn't make a teacher a good teacher, experience, patience, understanding, and firmness does. Not everyone with experience makes a good teacher. For example, my OW instructor grew up diving, his dad was an instructor and he has owned a shop and been an instructor himself for more than 15 years. He does all the Rescue training, including CPR/First Aid, for the surrounding counties dive teams and so forth, and he's serious about that type training. He also a friend of mine, but I won't take another class from him. Why? Because he isn't a good teacher. He is too easy for me. He is the type that as long as you pay his fee, you'll get certified, if you complete the required skills. He told me that the vast majority of his OW students will only be vacation divers and will most likely never dive without someone like a DM in the water with them. So he doesn't charge enough, nor take the time required to teach anything beyond what PADI mandates in the basic scuba course. I look for other qualities in an instructor. I'm not pursueing the training in order to obtain a certification. I persue the training to learn more about scuba and to make myself a better diver. So I look for an instructor that demands perfection, uses redundancy as a teaching tool, the drill sargent type. But I also want an instructor that is willing to put forth extra effort in the aeras that I may need extra training in. One that has patience and one that has alot of experience.
