How can you do that?
im asking because I recently bought a ECHOMAP Plus 95sv for console and trying to budget for a front unit at the trolling motor but was told it’s easier to buy another ECHOMAP Plus unit to transfer waypoints via Ethernet but if I can find a used unit in a different brand cheaper than buying a plus 75sv or 75cv then it would be great.
Is it better in general to have two of the same brands linked?
