For trolling set ups there is no need to spend a bunch of cash. I have been using cabelas depth master trolling rods for years with great success. They have many model as for different applications. I pair them up with diawa accudepth line counter reels and have never had issues. There are better more expensive reels, but these have been perfect for long line, planner boards, and lead core. I have 1 cabelas depth master reel and it seems a little cheaper built but I haven’t had any issues with it either.
Good luck and have fun in your search!!!
