I am replacing my old Pathfinder RLC/open array system with a Axiom Pro12S and Quantum2 Q24D. In order to fully use the Q24D functions (color marpa, overlay, etc.). I need a heading sensor. The recommendation is 10Hz or greater heading updates. My currently installed Pathfinder Smart Heading Sytem (with fluxgate, about 10 yeats old, fully functional) delivers 10 Hz over NMEA 0183, I believe maybe slower over NMEA 2000. It seems this should be adequate, if not optimal. I will never have an autopilot on this boat, so the EV1 seems like an unnecessary expense; the pitch, yaw etc. sensors donâ€™t seem applicable to my need for heading data for the Doppler radar unit. The Axiom accepts NMEA 0183 data. What do you think?
