I think it originated from the days before BC's and continued when the BC's were the horse collar types, in either case you were only dealing with a backpack and a tank - not so anymore....now even dealing with integrated weights and other assorted "add-ons" -knives, shear, lights... What few times I've done a beach dive , I gear-up off my truck tailgate or my partner assisted me and vice versa - if your'e in too much of a hurry to assist and check each other out, slow down - if your partner's busy..... patience. I'm one of those guys who has limited (if any) contact with my partner after we go down, so I def want him to eyeball my set-up and make sure things look pretty squared away.
First to Dr. Bill, I think if memory serves you will find the method detailed in the New Science of Skin and Scuba Diving and the Basic Scuba texts.
To NoVizwhiz, uh, there is no law that requires you to use all of that stuff, minimalist diving is not just a phrase. A Hog rigged backplate and single tank with a simple harness is easy to don with the overhead method. Weight integration is a dead end anyways, get a weight belt, simple, effective, flexible and modular.
