Performance Fins

Performance Fins have a rigid core that creates good drive and projection off bottom turns and cutbacks. The combination of the flexible edges and rigid core will help to make your board ride smoother, faster, and easier to turn. This will allow you to surf better, reduce fin injuries, and add more fun to the sport of surfing! Pro Teck Performance Fins with the rigid core are recommended for intermediate to professional surfers.

Pro Teck fins were developed after our son received a severe fin cut to his inner thigh that required over (200) stitches. As my wife and I watched the surgeon work on our son, I vowed to develop surfboard fins that would keep others from such a traumatic experience. We hope you are pleased with the Pro Teck fins and all the SurfCo products.
