Yes. I'm facing shore, leaning back and kicking to get out to the reef drop off (or close to it).You used the term "back finning" there and in your trip report. I have finally figured out that you do not mean back finning as I use the term. You do NOT mean being in normal, horizontal (belly down) trim, and using your fins to go in reverse. You mean, being on the surface, laying back and flutter kicking, yes?
In some areas, dive sites are immediately adjacent. For example, as you head south, Hilma Hooker, Angel City, Alice in Wonderland. Let's stay you start at the Hilma Hooker site, and go way south, turn and come back. So...did you dive all 3 sites? To some people it wouldn't matter; others might like to think they'd spent the dive exploring one (artificially categorized) named patch of reef.Doing the route of swimming one direction for 30-45, then back for 60-90, then back again for 30-45 was (in my mind) a way to never get TOO far from my entry point. But, swimming 60-90 in one direction first would maybe be a way to see things that divers don't normally get to?
To save gas at the outset. While some sites are close to the wall (e.g.: Oil Slick Leap up north), many sites (such as to the south) have substantial swim outs to the reef wall drop off (you may be looking at 300 - 500 feet). That sandy patch isn't all barren - I saw bone fish, sand tilefish, small green sea turtles, in the past I've seen southern stingrays, etc...When you start your dives, you swim on your back away from shore because...? To save gas and not burn it while swimming out across shallow sand? I was thinking that I would normally submerge as soon as it's deep enough and then swim out on the bottom (as gas is not really a concern when I'm on CCR).
But...I'm a gradually improving air hog of some years who's historically had to deliberately pause breathing and use pretty much every cheat I could think of (e.g.: I still orally inflate my BCD pre-dive rather than do it via low pressure inflator) to maximize my gas supply.
But I fin back in underwater, not at the top. How much air/nitrox I'm saving and whether it's worthwhile is debatable. But hey, all that extra exercise helps burn off some of those double cheeseburgers from the food trucks...
