CorQs Strike Indicators - There are a lot of benefits to keeping it natural with CorQs. Each dimple on the surface of these premium cork strike indicators provides additional lift and reduces atmospheric friction (kind of like golf balls), allowing you to cast farther with greater accuracy. That same porous surface texture displaces water quickly with less effort, allowing you to pick-up soft strikes that would otherwise go undetected. The rubber 0-ring connector keeps CorQs from slipping down (like some of our larger competitors) or damaging your line. And, finally, we have a variety of colors that will keep your eye on the prize.
