The Ardent SmartCull Professional Culling System is a first-of-its-kind, two-stage system that allows you to cull by color and weight. A series of six highly buoyant, impact-resistant balls eliminate the need for markers, charts or computers. The easy-to-read numbers record up to 15pounds, 15ounces, and setting weight on each ball is quick and simple. No more reweighing, extra handling or extra stress on fish. Thanks to SmartCull, it’s never been easier to make sure you’re keeping the best and getting rid of the rest.
