{"title":"Halcyon","description":"\u003ch2 style=\"font-size: 20px\"\u003eHalcyon — Thirty Years of Building the Gear Exploration Divers Actually Need\u003c\/h2\u003e\n\n\u003cp\u003eHalcyon started with a specific frustration: a group of divers who knew exactly what equipment they wanted and couldn't find it anywhere. Robert Carmichael and Jarrod Jablonski founded the company in 1996, and by 2001 had consolidated operations in High Springs, Florida — the heart of Florida's cave diving country, and as good a test environment for serious dive equipment as exists anywhere on earth. 2026 marks Halcyon's 30th anniversary, and the brand is still headquartered and manufacturing in High Springs.\u003c\/p\u003e\n\n\u003cp\u003eWhat makes Halcyon genuinely different from most dive equipment companies is the manufacturing model. Most brands select products from an OEM catalog, add a logo, and ship from a warehouse. Halcyon designs, prototypes, builds, and tests everything in one facility. The machine shop handles lathe, drill, and welding work; the fabric room feeds an in-house RF welder, one of the few in the dive industry, which produces all bladders, wing shells, inflatable signal devices, and lift bags. Every bladder is inflated for 24 hours to test integrity before shipping. Every light is pressure tested to 90m\/300ft. Quality control inspects every component on the way in and every finished product on the way out. The lifetime warranty on welded seams is only possible because the welding is done in-house, under controlled conditions, by the same team that designed the product.\u003c\/p\u003e\n\n\u003cp\u003eThe list of firsts that have come out of High Springs is long: the first exploration-grade rebreather system, the circular double-tank wing, the modular single-tank buoyancy compensator, the first commercially available P-Valve for drysuit divers, guideline spools, the first foldable underwater life raft, side-design guideline reels. These weren't marketing exercises — they were solutions to problems Halcyon's own divers encountered in Florida's caves and beyond.\u003c\/p\u003e\n\n\u003cp\u003eAt DiveCatalog.com, we carry the current Halcyon lineup as an authorized dealer: wings and BC systems, backplates, surface marker buoys, lift bags, and reels.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2 style=\"font-size: 20px\"\u003eThe Halcyon Product Range\u003c\/h2\u003e\n\n\u003ch3 style=\"font-size: 17px\"\u003eWings and BC Systems\u003c\/h3\u003e\n\n\u003cp\u003eHalcyon's wing and backplate systems follow the backplate-and-wing philosophy that's standard in technical and cave diving: a rigid plate (aluminum or stainless steel) provides ballast and structure, a harness wraps the diver, and a separate wing bladder provides buoyancy. This separates the structural and buoyancy functions that jacket-style BCDs combine into one unit — with meaningful benefits for trim, redundancy, and repairability.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eEclipse Wing\u003c\/strong\u003e is Halcyon's single-cylinder BC, available in 20 lb, 30 lb, and 40 lb lift configurations, CE certified, and engineered for stable trim and low drag in recreational through technical applications. The urethane-coated nylon wing pairs with interchangeable aluminum or stainless steel backplates and ships with a 22-inch LP inflator hose. The \u003cstrong\u003eStandard Single Tank System\u003c\/strong\u003e configurations combine Eclipse or Era wings with aluminum or stainless backplates in pre-configured packages, covering travel diving and technical training through the Halcyon Customize Tool for weight pockets, carbon fiber STA, and color personalization.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eStandard Twinset System\u003c\/strong\u003e uses the Evolve dual-bladder wing — 40 lb and 60 lb lift options — paired with an aluminum backplate and adjustable harness for twin-set cave, wreck, and decompression diving. The dual-bladder construction provides redundant lift: if one bladder fails, the other maintains buoyancy control. Upgrade options include the Legend MK2 wing, Cinch quick-adjust harness, and weight-pocket configurations.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size: 17px\"\u003eBackplates\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eStandard Stainless Steel Backplate\u003c\/strong\u003e is CNC-machined from polished 304 stainless steel for precise edges, consistent ballast distribution, and long-term corrosion resistance.

By 2001, the company had consolidated operations in High Springs, Florida — the center of Florida's cave diving community. 2026 marks Halcyon's 30th anniversary.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size: 17px\"\u003eWhy are Halcyon products more expensive than comparable-looking gear from other brands?\u003c\/h3\u003e\n\u003cp\u003eBecause they're genuinely manufactured differently. Halcyon designs, prototypes, machines, welds, and assembles products in-house in High Springs. Every bladder is inflation-tested for 24 hours. Every light is pressure-tested to 90m before shipping. The raw materials are sourced from military, aerospace, and medical supply chains rather than dive industry commodity suppliers. The lifetime warranty on welded seams is backed by the manufacturing process that produces them.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size: 17px\"\u003eWhat is a backplate-and-wing system and why do technical divers prefer it?\u003c\/h3\u003e\n\u003cp\u003eA backplate-and-wing separates the structural and buoyancy functions of a BCD into two components: a rigid plate (providing ballast and a mounting point for the harness and cylinder) and a separate wing bladder (providing buoyancy). Compared to a jacket-style BCD, this allows better horizontal trim, true bladder redundancy in twinset configurations, easier component replacement and repair, and a more streamlined underwater profile. It's the standard configuration in cave, technical, and exploration diving.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size: 17px\"\u003eWhat is the No-Lock® connector on Halcyon DAMs?\u003c\/h3\u003e\n\u003cp\u003eA proprietary connector on Halcyon's inflatable signal devices and lift bags that accepts both LP hose and oral inflation without a locking mechanism. The absence of a lock means the hose detaches quickly and reliably — important when you're controlling a rapidly ascending SMB from depth and need to release the inflator instantly.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size: 17px\"\u003eWhat is the difference between open-circuit and closed-circuit SMBs?\u003c\/h3\u003e\n\u003cp\u003eAn open-circuit SMB vents gas from the bottom as it ascends — which means it stays inflated as long as gas is being added but can lose volume if the inlet is underwater. A closed-circuit SMB traps gas inside with a one-way valve, maintaining volume regardless of orientation — more reliable for maintaining a consistent surface presence in rough conditions.
