These Ardent Smart Clips are to be used with a professional culling system. They offer anglers a fast and effective way to cull while reducing the harm and stress on fish in the process. The Smart Clips feature a no-puncture design that securely snaps to the lower jaw of fish without piercing holes in their mouths that can lead to infections or permanent damage. Built with a small hole in the bottom, the Smart Clips allow anglers to attach the clips to any puncture-style culling system they already own. Using Ardent Smart Clips helps improve fish care and protects our natural resources.
