That happened to me on Saturday to two of my senko at the local lake. It's known to have some large turtles there
True story (more than 6 years ago): Threw my rattle trap and was reeling fast. Bam, rod bend like I have never seen before. I was thinking that I finally caught a 15 lbs bass at the local lake until I saw the body. I was so dumbfound & my eyes just dropped on the dock, had to pick it up and put them back in place to finish the job. Man, it was a struggle to get it off his mouth. Thank god I had long pliers with me otherwise I wouldn't know what to do .
