I had sailed for years without a gps. I have been using one for less than a year now. I was very, very skeptical at first. I verified everything with charts and sight. I sail in the Chesapeake and sailed much of it last season. I continue to use other methods of navigation and always will. But I was amazed at how accurate the thing is. It is tempting to place too much reliance on it so Iím constantly telling myself not to. Perhaps because the Chesapeake is so popular for boating, the charts (hence chart plotters) tend to be more accurate than other areas of the country. Thanks for the input. SD Ė thanks for the 180.
One other use (but is brand specific and Iím not endorsing any brand of anything) is the integration of Google Earth with my chart software. It is amazing. I can zoom in on a marina and tell if it is primarily sail or power.
