The patent-pending, split-cavity design of Brad's Super Bait Cut Plug permits you to add scent or a bait fillet directly to the plug. Spinning, rotating action attracts hungry salmon and the scent provokes strikes. Effective on all species of salmon. The back of the lure is full or partial UV glow. Cut plug is best used for trolling, but can be effectively used for casting, plunking or back bouncing.
