Buy the Deeper Divers, won't have to worry about the ring, their better anyway. The ring could be glued on the dipsy, save the headache.
As mentioned above, your letting your line out to fast causing the dipsy to spin going down will twist your line around your Dipsy.
Fishing solo I set one rod in the holder and slightly loosen the drag so it goes out by itself slowly to your desired length while your letting the other out the same time.
Walker used to own the company that sold the Deeper Diver now Torpedo owns them.
