The first one I got did not work. ACK was great to send me out a new one right away. The chartplotter feature is invaluable for me. I did a surf launch in the Atlantic ocean and soon after the fog rolled in. We could not see land anymore. I used the chartplotter to lead us back to the launch area. The sonar and DSI seem to work ok. I have not had much experience with it to compare to other units.
