I just received a Daiwa Procaster baitcaster for my b-day yesterday. I can cast it pretty good for never using one before. I am just wondering what something is on the side of it. It has numbers all the way up to 10. Its on like 8 or 9 right now and cast good, no birdnest or anything. When I lower the numbers the it birdnests like u wouldnt believe. I am casting it pretty hard to. Is this for changing between flipping and long cast, long cast higher number flipping lower numbers. Thanks for the info, feel kinda dumb asking this.
