I have a Raymarine RL80CRC Plus radar and chart plotter. The GPS sensor went kaput and Raymarine is replacing it with an updated version at a pretty descent discount.*I noticed that I have a flux gate compass connected to my type 100 course computer and a Sea Talk Compass connected to the NEMA Power Plug side of my RL80CRC display unit.
In talking with a Raymarine tech he said to disconnect the Sea Talk compass, it is unneeded. It's input is ignored anyway as the flux gate compass info takes priority.
My question is why would the PO go to the expense of installing a Sea Talk compass if it's not needed and what's the difference between a Sea Talk compass and a flux gate compass?
Just don't understanding why I need another*direction telling me device when my wife always tells me where to go anyway.*
