True Wind vs Crazy Speed Transducer
I've noticed our Raymarine speed transducer gives very erratic readings. I don't expect perfection out of it, but is it normal to see it bounce around in an almost 2 kt range? We're in an inland lake, so I don't expect current effects. I pulled and cleaned the transducer, but it's still erratic.
This would not bother me, as I tend to pay attention to the gps SoG value instead. Trouble is, my wind instruments(RM ST60) seem to use the transducer speed for true wind calculations. Does anyone know if it can be configured to look at SoG instead? It seems like that would be the preferred choice, as otherwise current would affect the true wind calculations, wouldn't it?
I'm using a RM ST60 tri-data, st60 wind instruments, and a C80 chartplotter with a gps receiver.
