Berger discovered his most productive crankbait, the Ã‚Â¾-ounce deep-diving Yo-Zuri Magnum, in a bargain bin at the local outlet of a major sporting-goods chain. Although the lure is considered a bass plug, Berger wanted to go after walleyes big enough to consider the Magnum an average mouthful. So he bought 10 of the plugs. The first time he tried deep-cranking the Magnum behind a heavy weight, the walleyes mauled it. Berger immediately returned to the store and purchased the remaining 15 Yo-Zuri Magnums in the bargain bin. Berger later struck more gold when, in another fishing tackle department, he found a bargain bin that held 48 of the crankbaits, which he bought for $1.97 each.
