Computer and watch on right wrist. Bottom timer, forearm slate on left. If diving open water compass in DSS bungee mount on back of left hand, if diving wrecks-in my right thigh pocket. with the bungee mount on back of my left hand it puts the slate bottom timer and compass in one line that's easy to read and has all my info. I can monitor depth time and direction and with the right hand use a pencil to note features, points of reference etc without losing my heading. Kind of turns my arm into a console with the compass easy to remove or put on when needed.
