howarde:I do see the value in continuing education, like I am probably going to take deco procedures, and maybe trimix before the end of the year. That's not just a specialty though.
I think the tec/rec route is a viable alternative to either DM or Master Diver. Although I think it would be fun to be a DM in your area, Howard, for it me it would be an endless succession of "Try Scuba" sessions in the pool or assisting with OW classes in a cold, dark lake. You will learn to gas plan in tech classes and become a more confident diver with an understanding of redudancy and self-sufficiency while honing team diving skills. You can take the beginning classes in a single large cylinder with an H-valve, you don't have to dive doubles.
