Our Pro-Series Custom Blades are the standout feature of the Pro-Series Walleye Crawler Harness, and it's no wonder why. This 3.5 deep-hex Colorado blade has been specifically designed and tested to be deadly effective when trolling for walleye. With its UV coating, the blade provides high visibility, making it ideal for murky waters and low light conditions. Whether you're using a nightcrawler, leech, or minnow, any walleye crawler harness equipped with a Pro-Series blade consistently produces results. The blade works equally well at fast and slow trolling speeds, giving you the flexibility to match the conditions and improve your results. Don't miss your opportunity to have tournament grade spinner blades at a fraction of the cost.
