Hi Adrian  
This is a new version of a cutter for cables, ropes and ghost nets that I had made a few years ago based on an M200 motor. This one has the new M200 powering it and runs off one of the servo channels on the Navigator. I am intending to sell them on my website very soon. Price is USD300.

cheers
