Just looking for the run-of-the-mill IDC prices guys. Thanks for the info so far. Just to put things in perspective: I am 53 years old and have a great career in IT, I am not looking to work as DM but I do love to teach, I've taught/couched swimming, windsurfing, sailing, waterskiing, and other professional related courses for years, and I am doing this as a hobby. I want to teach OW and AOW in my spare time and I am not interested in teaching tech diving. I will sign up for a deep dive tech class this summer for the same reason someone else outlined: continue to learn. In addition, I am expanding my knowledge continously not just via training but also by reading the vast amount of scientific Dive material out there. I have also learned not to judge people's abilities on paper. Some people learn faster than others and where some may need hundreds or thousands of hours underwater to learn, others need a lot less and some people have a natural ability to absorb and teach effectively. Without disagreeing with anyone about this, everybody is different. Not that I am not tooting my skills just trying to explain where I am comming from. Thanks for the feedback so far.
