Sorry Darren, it appears I wasn't that clear.
If I jump in on Tech 2 level dive with 3 stages and the camera, I have the 50 and bottom gas clipped to the chest and hip D-ring on the left-side, the O2 bottle is clipped by a leash to the hip d-ring and the camera is clipped to my crotch ring. In my hands when I jump I have the camera in my right hand (as I don't want it to smack me in the face when I hit the water!), and the neck of the O2 bottle in my left.
Hopefully we will have the weather at the start of May to show you how we do it!
