Well, I designed (invented) the dang things as well as a tool for insertion of the urethane coil that is inside the tubular webbing so I *do* know how to make them but I don't think I'll tell. /ubbthreads/images/graemlins/tongue.gif /ubbthreads/images/graemlins/grin.gif
In addition to berkeleypoint.com, I don't know what dealers Cetacea might be selling these tethers to. I had hoped for a better market penetration than I have seen. If any of the dive stores in australia in your area handle the Cetacea line, they could certainly order some tethers for you. Have you tried BP?
