Garmim echomap uhd 743sv or 5212 chartplotter

[Cargile]

Limited budget. Both are used units. Will be used on the Great Loop. I already have a small echomap 43sv. Which would you prefer? Thanks

Since you have the small echomap already, I’d opt for the 5212. It’s more versatile as you can add radar that the echomap won’t do. Either one will be a good plotter, but I’m not sure what the touchscreen interface is like. I assume it must be usable though.
