Bigger crankbaits are great lures for targeting larger northern pike. The real big, deep-diving crankbaits are easier to troll than to cast, so you may want to consider trolling for some of those big pike that like to hang out in the deeper water. Crankbaits in the 5 to 6 inch range with some thickness work great for bigger pike. Those longer crankbaits that go as big as a foot long with also attract much bigger fish. Big pike eat big fish and a big crankbait is one of the best ways to simulate a big fish.
