I'm trying to get in contact with Catalina owner (C-28) Jim Cummins who posted a great photo piece on his
RayMarine rudder position indicator as an upgrade for an ST4000 plus
autopilot. My email is hardin (at) umich.edu. I've got the same
autopilot and would like to know where he got the sensor and if it improved his
autopilot performance. Thanks,
Joseph
