Anyhow, by direct reply to the original poster:
So... the dive computer and compass need to be in one hand, while the dive light is in the opposite hand.
This is the only way to see the gauges. - Whats wrong with clipping the SPG to your chest?? makes it easier to illuminate!??!
The reel must be in the same hand as the dive light (goodman handle). As I am right handed, the reel should probably go to my left hand. - with practice you become ambidextrous with the reel...
This allows easier spooling in. So the light is to the left. Compass and computer to the right. All seems clear. If I ever need to use the drysuit forced dump button, my right hand is free of gear, and button pressing is easy. Very nice. - Agreed.
But then...
My SPG is left in darkness to the LEFT.
Why is it so popular to keep the SPG to the left? - From my side, because its easier to read, and creates 1 less cable to come around from the right hand side.
I really can't see the point. I understand that it is the DIR way of doing things (like including a mostly useless DPV D-ring in the crotch strap while leaving out the right hip D-ring for canister lights - a fact that makes me a bit agnostic). - Why not have a D-ring on the right?? nothing to prevent you from doing so, if you so wish?!?! i know i do!!! in fact i have 2 on my right
Should I just learn to turn the light 135 degrees down/back, the SPG 180 degrees/upside down, and my head 135 degrees down? Is it just a matter of mastering underwater yoga? Or would it perhaps be more clever to be a heretic and just move the SPG to the right? - Youre call... entirely up to yourself. Only you can decide....
I admit, when i dive with indi's i have 1 x spg clipped to left chest d ring, and 1 x spg to right chest d ring. But honestly, the left chest spg is always easier to read, as you have soo much going on on the right, with your reg, your backup reg, your sling tank etc etc etc... whereas on your left, all you have is your inflator hose!!!
