I just purchased this chart-plotter and it's nice. It is a little on the basic side, but it has everything I need. The color screen is great (my old RL70 was B&W) and with only 2 wires to hook up it was as simple as it gets. I may look into getting a more detailed map, but we will see. If you are looking for a entry level chart-plotter, and want color etc, then for the $$$ you can't go wrong. Enjoy, Torrey Browne
