Halcyon Vector Pro HD Fins | High Density (Gray)

High-Density Performance. Perfect Trim.

The Halcyon Vector Pro HD Fins (High Density - Gray) bring the proven, propulsion-focused Vector Pro design into a higher-density format for technical divers who demand a heavier, more planted feel in the water. Retaining the same compact geometry and precise control the Vector Pro line is known for, each HD fin is significantly denser (1.6 density vs the standard 0.9), offering a balanced, negative platform without altering your kicking mechanics. They are the ideal solution for drysuit divers and technical explorers needing to offset the positive buoyancy of heavy exposure suits and refine their horizontal trim.

Trim-Focused Modularity & Control

Built for uncompromising flexibility, the Vector Pro HD Fins are fully compatible with the innovative accessory system used across the Vector Pro platform. This allows divers to further fine-tune their buoyancy using standard fin weights, heavy weights, or accessory canister housings. You get the benefit of starting from a denser, heavier fin body designed for demanding applications, with the ability to micro-adjust your configuration based on the specific environment and equipment setup.
