I have the 5208 garmin. Nice plotter but a little slow on the redraw. I would recommend the 7200 series. Have lots of experience with units. In the marine electronics business. Ck out some of the new ray marine ewides also. Hybrid touch and better chart features from navionics. recommend the sat weather option also.

Agreed, it is by far the easiest and most intuitive unit I have used. We had the hd radar built in, and it would overlay over the chartplotter. I also found it to be incredibly accurate, both distance to a channel mark and depths. With the size of the screen it was also very easy to pan around and look at the surroundings. Also very easy to see even in direct sunlight.

If your concerned about dash space this is a good way to go.
We went with the 740S (Depth sounder option)
I have it mounted right under our smartcraft and tied in to XM weather as well.

have had the garmin 182C in numerous boats and am looking for a used one as we speak
