Church Tackle's CO TX-007 Stern Planers will keep all of those lines separated and under control. Great for trolling in a congested area, the stern planer staggers your lines, letting you fish them at different depths and at different distances. This keeps lines from crossing, and it allows for more lines to be used off the back of your boat. It can also be run off of downriggers or be used as a buoy marker. Its professional-grade design performs with such little drag, you'll see the action in your rod's tip when a fish hits. Easy to set up, it attaches to line with a clip on the nose and a quick-swap swivel in back.
