Robo's machine is entirely different, they use MANY single cavity molds on a carousel that rotates to the 3 nozzles and the 4th salt dispenser, their baits are definitely made in house out in CA. Caught just enough in a video clip a few years ago. Southern's is a CNC deal Zorn built them and they copied (5 times). Funny tidbit of info, that entire MASSIVE operation was moved to Costa Rica in the last couple years. They lost something like 80% of their customers, including Zoom and BPS (their 2 largest clients).
