The "Spinner Rig" tipped with live crawlers has long been one of the top techniques used by anglers to put more Walleyes in the boat. The Gulp!® SR Crawler was developed in cooperation with Korey Sprengel, THE top walleye pro on crawler harness techniques, to deliver the right size, scent, flavor, color, and most importantly, the right action that replicates a real live nightcrawler when used on a spinner rig. The SR Crawler delivers on every key benefit of a live crawler with the added durability, convenience, and color options you can only expect with Gulp!
