Dive instructors

[SCUBA Dog]

I agree with Eric. There is no substitute for time spent underwater. However. I think that classes and formal education are important as well. I was originally certified as an o/w and advanced diver in 1985. I knew I needed to improve my skills. After a few years I thought I was a pretty good diver. In the late 90's I took the NAUI advanced, master and several specialty classes. I then found out how much I didn't know and how much room I had for  improvement. The information from the classes, the guidance from some really good instructors and time spent underwater in a variety of conditions combined to make me a much better diver. I agree on the importance of time spent diving, but do not dismiss the importance of formal education, which exposes one to more in depth information as well as practical experience diving in a variety of conditions under the watchful eye (to provide both praise and constructive criticism) of an instructor. Couldn't agree more on his points 1 thru 5. Particularly reviewing and learning from your previous dives. Don't forget to log them so you can look back and benefit from them. Second, don't skimp on your life support equipment. Not only make sure you buy the best, but make sure you maintain it and have it serviced regularly.
