HALCYON WAS THERE

John Kendall - GUE Instructor and member of the Symbios CCR test and training team, has been diving since 1993 and using Halcyon equipment for more than 25 years.

As John says:

"My history with Halcyon is almost as long as my history of diving."
His first Halcyon product was a Pioneer 27 wing, purchased around 1999 or 2000. More than two decades later, he still owns it and uses it while teaching his 10-year-old son to dive.
Over the years, John has used Halcyon equipment for single tanks, doubles, sidemount, rebreathers, and countless cave dives. From halogen canister lights and HID upgrades to the RB80 and today's Symbios CCR, he has witnessed decades of continuous development and innovation firsthand.
Thank you, John, for sharing your story and for being part of the journey.

Vector Pro HD Fins – High Density

The Halcyon Vector Pro HD Fins bring the proven Vector Pro design into a higher-density version for divers who want more built-in weight and a more planted feel in the water. They retain the same compact, propulsion-focused shape and precise control the Vector Pro line is known for.

Each HD fin provides increased weight compared to the standard version, offering a more balanced platform without changing the familiar fin geometry. This makes them ideal for divers fine-tuning trim across different equipment setups.

SPECIFICATIONS

🫧Available size: XL
🫧Relative weight: One HD fin equals the weight of one weighted standard Vector Pro fin (1.33× heavier than the standard fin without the weight)
🫧Density: Standard fin: 0.9 | HD fin: 1.6
🫧Compatibility: Standard fin weights
🫧Compatibility: Heavy fin weights
🫧Compatibility: Fin accessory accessory housing (canister)
🫧Use case: Divers seeking a heavier fin platform and added trim flexibility

Explore without limits. Engineered for innovation, crafted for experience.
Halcyon began as a group of passionate divers who couldn't find the gear they wanted in any dive store. We quickly realized that many other divers shared our desire for innovation.

Celebrating our 30th anniversary at Halcyon felt incomplete without a mark to represent it.

The idea started with something simple. In traditional terms, a pearl represents thirty years—formed underwater, shaped over time, layer by layer.

That process mirrors how Halcyon has grown.

Read more about the thinking behind it.
