Before your first open water sidemount dive, practice on land. Put on your rig with full tanks. Sit on a bench. Close your eyes. Reach for your left valve. Now your right. Do this 50 times.

For two miles, the train crawled along the rusted freight line. It was slower than a bicycle. But it was moving. And at the end of that line was a emergency station—unused for decades, but intact. Elias had checked the blueprints years ago. Your tank valves are the most exposed part of your rig
There is no single "correct" way to configuration a sidemount system because environments dictate your needs. A cave diver in Florida using aluminum 80s faces different challenges than a cold-water wreck diver in the North Atlantic using steel 120s.
Perform the Snake while standing, then again in the water before descent. The second check is vital because water pressure changes the way hoses lie.
