Devil’s Den is just one of those places that no matter how careful and streamlined you are, you’re bound to scuff something up. I dive there quite a bit and my tanks generally make contact with the rock in one way or another (most likely because of my size... 6’4" tall and a large frame). I use an OMS wing and my pressure gauge is clipped to my D ring on my harness - so close to me that I don’t have to even it touch it to see my pressure, merely look down at my chest. Also, I wear my computer on my wrist and it really keeps my scuffs to a minimum - and the face cover helps, too!
