Top-of-the-range travel BCD for recreational divers who demand technical precision. Compact enough to check in. Precise enough to trust at depth.
VOYAGER is not a compromise between recreational comfort and technical performance. It is both, simultaneously — because we refused to accept that you had to choose.
Built on a backplate and wing system, VOYAGER places buoyancy exactly where physics dictates: behind you. The result is natural horizontal trim, effortless movement, and a dive experience completely different from any jacket BCD.
Designed by a team of technical divers who wanted to bring DIR and Hogarthian principles into the recreational world — without complexity, without compromise. Read more: DIR Philosophy.
Most BCD manufacturers start from an existing shape. We started from mathematics. Our team built the entire air volume geometry parametrically in Fusion 360 — every cubic centimetre calculated, every curve intentional. The buoyancy centre is positioned precisely to deliver neutral horizontal trim without diver effort.
From the 3D model, we generated the flat pattern for every panel of fabric. The seamstress who sews VOYAGER works from drawings derived directly from engineering data — not from approximations.
Why it matters: a BCD designed mathematically trims predictably. You set your buoyancy once and the wing holds position. No fighting the equipment. No constant micro-adjustments. Just the dive.
Buoyancy trim, comfort, inflator response, backplate fit — everything validated in real conditions by our team. Exactly as designed.
Note: these photos show Prototype #2, currently in active testing. The final production wing will feature corrugated inflator hose with IN/OUT buttons, refined hardware and styling improvements. The bladder geometry and overall shape are close to final — the wing performs exactly as designed.
The development of VOYAGER started with a technical single-tank wing — 16 litres, asymmetric, more lift below than above. As we tested, we realised the first product should be recreational: less volume, lighter, ideal for travel. Below is the story of how the form evolved through four prototypes, ending in the production version.
Note: this section documents the production history of VOYAGER. Once development is complete, a dedicated product page will replace this one, and this history will remain as a record of how the wing came to be.
This is the exact geometry of the air inside the bladder when the wing is fully inflated — calculated parametrically in Fusion 360. Every cubic centimetre is intentional.
What you see is the shape of the air itself — not the wing, not the bladder. The volume that determines how the BCD behaves underwater.
The centre of buoyancy is positioned below the geometric centre to deliver natural horizontal trim. The asymmetric distribution — more volume below, less above — eliminates the constant effort most divers don't realise they're making.
We are looking for retail partners, dive centres and distributors who share our standard.
