Product Information
Not intended for direct purchase. Please use one of the Halcyon "Build Your Own" product pages.
The Halcyon Custom BC Upgrade (Made to Order) is a component line used by the DiveCatalog Halcyon "Go Custom" configurator: each variant represents one factory upgrade or fee that belongs to a customer's custom Halcyon BC build, and it is added to the cart automatically alongside the matching base system line. The fourteen selectable lines cover backplate, wing, STA, harness, weight pocket, custom color and embroidery options (part numbers 10.000.801 through 10.000.979 and 10.040.030).
Who it is for
This line is for divers who are configuring a made-to-order Halcyon backplate and wing system and want factory upgrades built into the order rather than added later: a stainless steel, deluxe aluminum, deluxe steel or Pro carbon fiber backplate, a Legend MKII or Era wing, a weighted or carbon fiber STA, ACB weight pockets, the Cinch quick-adjust harness, a Cinch accessory kit, custom colors or wing embroidery. It is a build component, so start from a Halcyon "Build Your Own" page and the matching upgrade line is attached for you.
Key details
- Fourteen upgrade and fee lines, one per variant, each tied to a DiveCatalog configurator item number.
- Cinch Quick-Adjust Harness Upgrade converts an existing Halcyon backplate to the patented Cinch infinite-adjust system, which can be tightened or loosened while worn.
