Hi guys as the title says ive decided to try to setup my boat for crappie. I know i want a spot lock troller and new graphs. Im trying to decide if i should try to save money and buy used or just buy new. I would love to have a live scope setup but think its probably out of my price range. ive been looking at helix9s and 10s with mega imaging. kinda overwhelmed really would like some of your opinions. my main goal is to be able to find brush and shoot under docks.
