I have a used in good condition Seac KS01side mount BC. Thoroughly rinsed and cleaned after each use. Functions perfectly just switching to a new set up and need to sell this one. I paid $600 new for it, asking $400 but open to reasonable offers. Feel free to message me here or text me with any questions or offers. 352-223-4945 Dustin.
