I do use one of the coiled lanyards for my camera. It clips up to short when the camera is not in use, and when unclipped, extends to allow me to use the camera. I do know photographers who simply clip the camera to their BC and unclip it for use, but I'm too paranoid (and probably too cheap) to contemplate losing it altogether, should I drop it.
Me, too. My camera rig is too expensive for me to carry without some kind of leash, so I got one of
these. I've exchanged the suicide clip - which was close to impossible to operate with thick wetgloves, or drygloves for that sake - with a big-a$$ boltsnap. Works nearly perfectly for me. In addition, I've tied another boltsnap directly to the rig, so I can basically sling the camera rig like a pony or stage bottle, between my left hip and left shoulder D-rings. Compass, backup computer and slate are forearm mounted, and my primary (AI) computer is clipped to the left hip D-ring with a boltsnap.
Everything else (typically roll-up snorkel, extra slate and dSMB) except for my catch bag is carried in my DS pockets. Usually with a lanyard attached to the bungee loops in my pockets. Some via a boltsnap, other stuff with a loop-in-loop attachment. Depends on whether I need to take the stuff completely off the bungee loop to use it, or if I can operate it while it's still attached to the bungee loop. The catch bag is clipped to the rig via a double-ender.
please don't carry a pistol-grip light attached by a lanyard and then drop it to deal with something. It will spin like a disco ball, creating a signal that looks VERY much like an out-of-gas signal. If you are diving with someone who is trained to light signals, that person is going to be jumping out of their skin every time you let your light go!
Ay-men. The disco ball effect from my first light (a UK C8 with a pistol grip) when I let go of the handle to leave it hanging by the lanyard was about equally annoying for me and my buddy. I don't need a can light, so I've opted for a SOLA as my primary light, but the location (on top of the left wrist) isn't too different from the location of a tec/DIR can light on a Goodman handle. It just sits there, and I don't even have to think about holding on to it. My secondary light is carried GUE/IANTD/DIR style, with a boltsnap tied to the end and clipped to a shoulder D-ring and secured to the webbing with a piece of inner tubing.
