4 years a happy customer Tuesday 14 November 2006 We are enthusiastic users of the transponder for 4 years. A number of people have asked us about it. If you have a copy of the Practical Boat Owner review of December 2002,would you please email a copy? I find I have the YM article, so no need to send, but I would appreciate the PBO one. On many occasions we have seen ships avoid us if we are the stand on vessel in a way which we had never seen before. Very reassuring in poor or nil visibility while tracking ships on our radar. Sometimes we have been radiotelephoned if they are the stand on vessel, if we are passing close astern them. Hope we look about their size.
