Update: after degreasing the tension knob and tightening to re-engage the detents, I fished all day Friday and the knob definitely kept loosening about as much as it did before.

Next step will be to add some blue Locktite as suggested. Or, I can wait till Quantum ships me a new tension knob, which their warranty dept did last week and should arrive soon.

 

Ironically, this whole episode has made me a better baitcaster because I’ve learned how to use thumb pressure with a very loose spool to control the cast. I still backlashed a bit on Friday doing that, but not nearly as much the prior week. There was almost no wind, so I’m not taking full credit! 

I would opt for teflon tape over the blue Loctite.

Update: ordered a replacement tension knob from Quantum, voila, problem solved and reel works fine. Darn good reel for the $.
