from what i remember reading back then was that the US part that RF had was sold but whatever products was being made in Germany is STILL being made there - correct me if others heard otherwise though .....
They are now owned by Maxxsonics, but from what I've seen, the product hasn't cheapened, worsened, or integrated with anything other of the companies affiliated with Maxxsonics. From what I've seen, they're letting the German engineers do their own thing.
They were owned by RF, now they are fully owned by Maxxsonics (regardless of distribution location, US or anywhere else)
