Using your digital mobile device and marine-specific app, you can even record a movie of your chartplotter screen to share with friends and family.
Let’s take each of these questions on one at a time. First off, a chartplotter/fishfinder is a unit that has both chartplotting and fishfinding functions built-in. An MFD also has both of these capabilities, but it can be expanded to act as the hub of a more advanced system. With an MFD you can add things like radar, autopilot and/or stereo control, digital gauges, camera inputs, and a whole lot more. Sometimes these units are plug-and-play, and other times you need to add black-boxes and software updates. The chartplotter/fishfinder, on the other hand, isn’t expandable (though some units do offer limited expansion abilities—their proper definition is debatable).
