I missed the original post. I use a 10 inch Northstar 6000i and generally like it with a few comments as follows: 1) I wish that it would allow the boat to be offset so that you had maximum chart in front of you. As it is, the chart behind you is the same as the chart in front of you. Once I miss the obstacles, I am not all that concerned with what is behind me! 2) I still have not gotten completely used to the cartography and in particular the fact that some nav aids show at different scale levels. If you are at the wrong scale, a nav aid may not show. I have had to adjust scale to see a nav aid that was plainly visible to me through the windshield in order to confirm it on the screen. I run a 6000i because I do not have room at my helm (within touching distance and within eyesight of these aging eyes) for a laptop system due to the helm configuration and slope. I considered running a laptop output to a screen but still could not reach the laptop without stepping away from the helm. Therefore, went with the 6000i and find it excellent for this application. I do not have any radar or depth sounder features on mine and use it solely for the charting and tide features. I run a lap top near the helm and use that for planning purposes and monitor that when someone else is at the helm. I find the 6000i screen to be excellent in all light conditions and its controls and features to be very easy and intuitive. We installed this equipment on the boat this year and put 180 hours on it in all sorts of conditions. Based on that experience, I an sure that we made the right decision and would absolutely repeat the installation again. If you have any specific questions, feel free to e-mail me.
