Yellow Bird Planer Boards form a solid block of flotation and are internally ballasted, so the board always rides upright until the line is released. The planer boards large surface area increases buoyancy and allows it to carry big crankbaits and lead core line up to 150 out to the side of the boat. Now even small-boat, small-water, small-species anglers can realize the advantages of planer-board trolling. The Yellow Bird Small Planer Board does everything a regular-sized board does to increase your coverage zone and avoid spooking the fish you want to catch. Great for crankbaits, spoons, spinners, and live bait rigs; use the Large Board for the buoyancy needed to troll the largest deep-diving cranks. Made from durable recycled ABS plastic, each Small Planer Board measures 5-1/4L x 2-3/8H; each Large Planer Board measures 10L x 3-1/2H. Both large and small come equipped with 2 adjustable, spring-loaded pinch-pad releases. Available: Small Port, Small Starboard. Large Port, Large Starboard.
