Go diving?TheRedHead:How does the average diver learn to master the kicks and diving position without instruction?
Seriously, you know you want to get from point A to point B, under control without silting things up; you know you want to be able to perform basic skills like mask clearing and regulator retrieval and air sharing while keeping control of your buoyancy and without mucking it up - this stuff isn't exactly Rocket Science. By diving, and by trying out different things on your own, you can go a long way towards figuring out what works for you and what doesn't. When you see someone whose technique is particularly good, emulate that; ask for pointers. Most nice folks want to help and will give you more than "take the course" for this basic stuff. Then when you do take a course (like cavern, for example) you'll fnd yourself mostly honing skills rather than having to learn completely new ones.
Go diving; have fun...
