Also, out of curiosity, I see five hoses in the third picture. What is the third right hose for that is tucked under the diver's arm?
The hose running behind Marc's right shoulder is his 7' primary. It runs down to his waist, back up his left chest, around his neck, and to his regulator. The hose running behind Marc's left shoulder goes to his SPG, which is clipped to his left waist D-ring.
