*Keith, I am with Walt on this.* I have two 10" displays side by side.* When offshore I usually run the radar on one and the chart on the other.* When running in limited visibility or confusing areas, I use the overlay feature to distinguish targets from navigational aids.* It is a wonderful feature---especially at night or in fog.* It takes awhile to really learn how to use it as when turning sharply, the radar overlay*lags the chart plotter.
From starting with a chart and compass to an*RDF, then Loran A single track with an ocillascope to tune, to Loran C, to GPS and chart plotters, I've done it all.* I am a generation or so behind the very latest technology, but light years ahead of where I was.
