These crank baits come in great depth and detailed fish patterns. Built into the top of these lures is a small indention designed to “whistle” while they move through the water adding a different tone and frequency to the rattling of the crank bait. This has proven to attract some serious strikes! Use them as a go-to for big bass or use them as a highly effective search bait! Either way you WILL catch bass on these lures! Each lure comes with 40# split rings and triple grip mustad black nickel hooks!
