I am looking at a lowrance HDS 5 with a 1800 HD radar, what are my options for chart overlays I believe it would need a heading sensor? Will a flux gate compass work like a Raymarine or what do I need and how economically can it be done?

You can use the KVH autocomp 1000. As of right now I still don't think the HDS units are capable of overlay even though it says so in the literature.

You can use the KVH Autocomp as proposed by Jim if you don't plan to use the NMEA-183 input for something else. HDS-5 only has one NMEA-183 port.

I have a Maretron SSC-200 connected to my NMEA-2000 network, originally installed as radar heading sensor for E80, the heading info are of course also showing up nicely at my newly installed HDS-5.

SSC-200 has a built-in rate gyro so it's able to give better quality heading info than KVH Autocomp in rough seas. The only disadvantage is a bit cumbersome calbration without a Maretron display. For calibration I had to connect the compass to the serial port af a laptop, and then sendig commands using Hyperterminal.
