I have a Zeagle Zena (biggest fan on earth!!) and because I bought it from ScubaToys, I didn't have anyone to show me how to rethread it. I turned my Zena over in my lap, looked carefully at how it was threaded, pulled the cord slowly, and watched it come out of the loops. Then I simply rethreaded it exactly how it came apart. I'd say the first time it took me 5 minutes from start to finish, including watching how it came apart. After that, I pulled the cord and it took me approximately 2 minutes to rethread it the 2nd time. Don't let ANYONE tell you that you can't rethread it yourself.
Let me tell you one MAJOR advantage to Zeagle's ripcord system. While in Belize in December, one of my husband's weight pockets from his SeaQuest BC came out and there was no way I was going to dive to about 400' to try to retrieve it. Not only was he not able to use his integrated weight system on that side of his BC (he simply put the weights in his pocket), but it cost us nearly $25 when we got home to replace ONE pocket. The same exact thing happened (in Cozumel) to a friend of mine who has a SeaQuest Diva, only her LDS charged her $35 to replace the pocket!!
I never have any pockets I ever have to worry about losing or replacing. I've already told my husband that the minute he's ready to replace that SeaQuest BC, we'll be buying him a Zeagle.
