I've said enough about Fundies today, but I have to say I felt that way looking at a coral reef after Fundies. In a post above I described the effect as "freeing up some of the mind's bandwidth from the mundane bits and letting the diver focus on whatever it is that's important to them, whether that be looking at pretty fish or whatever."Nah that is when the real fun begins. Because you don't have to think through diving, you can now spare brain power to activities that don't directly have to do with the dive itself.
I've said it a few times in my thread in the technical forum, the cave I saw during my cave course or in the dives just after I got certified looks night and day different from the cave I see today. "Is that a clay layer? Looks at those drip marks down the wall. OH LOOK A FOSSIL!"
