As posted elsewhere, Arne Sieber of Oxygen Scientific appears to have the patent on most of the relevant technology of the Symbios - magnetically coupled transmission, the HUD, the oxygen sensor, the fancy double-hose BOV.I'm extremely curious how much Halcyon has done beyond a branding/distribution deal with Oxygen Scientific Diving. OSD promoted the RNO interface, the Rhino-1, Rhino-HUD on Facebook as far back as 2023. They even had a rebreather then that looks extremely close to the Symbiosis.
My assumption is that Halcyon is lending its not-insignificant experience with the manufacturing, regulatory compliance, dealership network and the like. I did see that the FCC licenses in the US are filed in Jarrod’s name, so that tells you something about who is doing the regulatory work.
