Protect your GoPro from accidental falls. 
Attach the metal tether cable to any object for added security. The two-loop rope cable tether for GoPro HERO cameras is covered with a thin plastic vinyl protection. 
The stainless rope cord cable leashes are rust-resistant and can be used in salt water as marine security lanyards as well. 
This tether is attachable to the thumb screw included with all GoPro camera housings. The loop goes around the screw side and is perfectly sized so it doesn't come out on the thumb side. Two or more units can be linked together to extend its length. Attaches to the standard GoPro thumb screw.
