Humm....
Dive knife is a folding, blunt tip knife with a line/strap cutting hook - in scabbard on waits belt of BC on left side of belt buckle.
SP gauge, compass, computers on HP hose then clipped with a retractor to right side D ring on BC shoulder strap.
Boat dive safety kit in DiveRite clipper pouch on BC waist belt around right side - Includes signal mirror, storm whistle, surface marker and white strobe light.
Dive light, when needed, attaches to right shoulder strap D ring on BC with a nylon lanyard, then hangs via a snap clip attached to the handle of light - Either a UK C4 or D6 light.
Camera is stowed in a DiveRite horizontal zipper pouch on front of BC on waist strap, unless I am using the strobe. Then it just gets clipped off to a D ring on my left side BC shoulder strap.
Any other tools/accessories that I might carry for a particular dive just get clipped off on an open D ring. I have plans for a cave/wreck spool in the future that I will probably stow in some sort of pouch or pocket. I am also planning to get some X-shorts so I will have some extra storage.
