I have the garmin 942xs with the fantom 18 radar. Probably one of the best setups going, I am upgrading to an 8610xsv for a little bigger screen but the chart overlay works awesome, except if you have lots of tracks in one area. I normally run chart plotter on one half and radar on the other half. The fantom will pick up pieces of wood, seagulls, heli’s, water planes, and even your own wake on super high definition I keep my turned down a little and ran around and played with it during the day for a while first. The fantom also has dual range so in heavy fog I use one zoomed in for sticks and deadheads, and one zoomed out for boats etc... and then chartplotter.
