Let me add a tad of info for options ...

The Ulterra has GPS ...
The Minn Kota puck is a heading sensor only ...

It is possible for the HB to subscribe to use the GPS from the Terrova and the heading from the Minn Kota puck ...

HELIX units cannot separate the functions - it’s subscribe to both GPS and heading from the Ulterra/Minn Kota puck ... or get GPS and heading from another source ...
