What is the strength of the coil? How much weight before it breaks, 5lbs, 20lbs, 50lbs?
JAMES L I know it will support 30 pounds of camera/strobes/arms...
MYLES M Have not broken mine, but under water it could probably support 50 lbs, the coil lanyard is perfect for larger lights
CHUCK B Mine has never broken so I don't know.
ROBERT U I've used this for lights, SPG and generally light equipment. I have used it to tether a scooter but under water its only slightly negative so not much weight was ever attached. Doubt it could hold 50lbs (e.g., full 120cf steel tank). I'd keep lighter equipment (less than 10lbs) for tethering, not carrying. It seems to be made well and i just started using it again (no more scooter) for SPG.
MATTHEW F I think the specs that came with it said it would support 6 lbs. I use it for my camera (Ikelite with wide angle attachment + strobe) but I've never just it dangle by the coil so I don't know how strong that part is. I will let the system dangle if the clips are connected and that part is strong/secure.
