I am curious, what aspects of Scubapro/Halcyon/Apeks units are notably better than the comparable HOG/D6s in your findings?
For me it’s reliability- I’ve had many issues with IP creep with D6, Apeks have always worked, after hundreds of dives no issues. I know many people who have had the same issues and much better results with Scubapro/Halcyon or Apeks. I would also say that Apeks breath better- I still have some D6 in the mix as stage regs and going directly from Apeks to D6 is quite noticeable, even after adjustments. I will say that D6 has always fixed any issues seamlessly.
