iv used my Penn Fathom 40 since I started shark fishing about 2 years ago, havnt had problems until this year, the Fathom had 2 dog gears which is really nice but 1 will keep jumping out after replacing it and it seems to jump out every time iv loosen the drag after im done using it and then when I tighten it, I can hear it jump out and then im stuck fishing for the rest of the session with 1 dog gear. Any idea on how to fix this???
