Looks like a mini navy war ship... a very small one. Unfortunately, most civilians no longer use those type of screens with the green and black. It's an adequate back-up GPS because it has an external receiver and it includes a rudimentary world map and it plots the boat's GPS coordinates on that map, but there are much better modern plotters, depth finders, and radar systems available these days. Do I need them... no. Not at this time. So for now I will keep things as they are. But when I cross oceans in this machine, it would be useful to upgrade. Nevertheless, I won't stop watching the actual navigation aids when possible.
