The 7200C is a pretty good chartplotter. Where it shines is in screen size for the price, ability to do NMEA2000 well, screen resolution, and capability to expand into radar and Fishfinder.
Where it fails is it is not the easiest to use. However, most people that have learned the Lowrance interface tend to stick with it as they really like it. I have no problem in recommending this as a chartplotter. You might also consider the Standard Horizon CP300. If you do go for the 7200 make sure you get Navionics charts for it, they are much better than the Lowrance Nauticpath charts.
