Maybe you have your left / right--- Port / Starboard reversed. The end with the clip needs to be facing forward (bow) and normally each one states right on it which side. Next there should be, a "tension adjusting screw" on the clip. I would say a 1/4 to 1/2 turn to the right, "righty tighty, lefty lucy", increments; but this could still lead to false hits. I just put the line farther into the clip; not just at the end. Sometimes it will release depending on the size/ weighted sometimes it does not. So; even my method, I have to "fiddle around with it"; but my motto is -- when all else fails read the directions. * Note* I generally set my planers out to the side 50 ft indicated on the reel.
