The OCT Jigs are the only surface irons you'll ever need. They are 100% CNC machined from solid billet aluminum. This means that each jig is exactly the same within 3000th of an inch. Because of this, each jig swims perfectly! No more searching the jig wall and hoping that the jig you picked actually swims. OCT Jigs feature a textured body that creates more drag in the water for a better swim. All of the jigs are either powder coated or anodized for long lasting finishes. Weight is 3.5oz.
