I’m after a second hand 4 inch dredge in good working order. Ideally a Keene or Proline with Honda GX200 etc. I don’t need an air compressor. I don’t mind traveling in South Island to pick up within reason. But will want to test it. And have an idea of hours on the engine etc. 
So if you have a decent 4 inch gathering dust and want a reasonable price DM me.
Sorry but not interested in home built. Would consider homebuilt frame and floats with Keene or proline box etc.
