Had no idea how to word this but hopefully somebody will recognize this issue and it will be an easy fix. Probably something simple I should have caught myself, but for the life of me I can't figure this out. Just bought the reel, took it out this last weekend running and gunning for shy yellowtail, Never got a look so I'll leave it at that. I filled the reel with 310yds of 50 braid. With a 4' top shot of 40 fc. And yes I put tape on the spool before the braid. I set the drag that morning and after about an hour of running and gunning casting to breaking fish. I just happened to check it. It had loosened considerably. Didn't think anything of it. Tightened it back up set and went back to casting jigs. After about half an hour checked it again. Once again it had loosened. Now I'm concerned, took the cap off made sure the spool was seated properly and tightened it back up. Made about 30 casts and again loosened. Never once pulled on that drag, just casting and reeling??????? Someone please tell me what I missed. Sent and Email to Quantum this morning but as of yet no reply. So thought I'd come to the experts. Overall opinion of the reel, regardless if this problem had occurred or not. Smooth as silk great drag, casts great, line lays well on the spool. Have yet to pull on anything so I'll post that when it happens. Overall I wouldn't put it in the same class as my original model Saragosa 14000.
