Default Raymarine Dual C-80 or C-120

The Phoenix I bought this summer has a C-80 and an older Radar Display and GPS/Loran. The GPS/Loran works ok but the only reason I use it is that the Autopilot is attached to it. The Radar does not work at all. I had purchased a C-120 with compatible radar to go on a project boat that I have since sold and have been thinking about installing that this winter and eliminating the GPS/Loran and dedicate Radar Display.

A friend has been trying to convince me to go with dual C-80 displays instead of the C-120. He happens to have a C-80 and wants to trade me for my C-120 (plus cash of course). I realize that the 2 units are not able to share much but was wondering if I could get some opinions. The C-120 seems to have a better display but having GPS redundancy does have its merits. I was thinking of the Radar and GPS on one unit and the Sounder and GPS on the other.

So looking for opinions on having 2 C-80 vs. 1 C-120 and how you would set up the C-80s if you went with 2.

I have a single original e120 [basically the same as a c120]. I like the radar overlay better than a dedicated radar display. I also like being able to view the chart and sonar display right next to each other when looking for a fishing spot.

If you want GPS redundancy, just add another Raystar GPS receiver. I have one connected to my e120 and another connected to my VHF. If either fails I have a DPDT switch that puts the working GPS output to both devices until the broken one can be repaired.

I really appreciate having a larger display when plotting a course in unfamiliar areas. I vote for using the larger display.
