On the Carcharodon, we use only PENN Rods and Reels the most reliable and warrantied in the world.
Why? LOLOF, we've busted rods, broke reels many times while 'outclassed' by a larger fish than expected and PENN just sends a new rod, repairs the reel and away we go. We love 'em!
Every spring, all the Penn Reels get their spring tune-up. Drags are replaced, springs, nuts, bolts and anything else we see wearing are changed out.
New line is put on to start the season; and changed as needed.
