Halcyon Vector Pro Fins with Weights

Halcyon Vector Pro Fins—a breakthrough in power, stability, and customisability. Engineered for high performance in caves, wrecks, open water, and cold-water environments, these fins eliminate the need for multiple styles. One compact, durable solution delivers everything you need underwater.

Built from tough, eco-friendly Monprene®, the Vector Pro’s innovative blade and ballast system give you precise control over propulsion, trim, and buoyancy. Whether you’re navigating tight restrictions or kicking hard into a current, these fins offer unmatched versatility and efficiency.
