Comments about Aqua Magna-Clip with Clip & Split Ring:
Great for tethering lights, camera, lobster gauge and just about anything else you don't want to lose to you BCD. Easiest and best lanyard I have found for re-attaching any of the items listed above during a dive. No more fumbling with buckles you can't manipulate properly with a gloved hand. Only one catch, don't use it to connect your compass/console to your BCD - it's magnetic.

I use mine for my camera and video camera. I have one end attached to a D-ring on my chest. When you don't feel like holding the camera the magnet keeps it tight to my chest; when I'm shooting the magnets come appart easily and I can stretch my arms all the way out.
