Comments about Standard Horizon Standard Horizon CP500 Chartplotter:
A good chart plotter at a good price. Lots of NMEA ports -4 in and 5 out- means you can connect AIS, VHF, SSB, AP and other instruments without likely needing a MUX. Support for Max Wide CMAP means one chip covers huge area like East Coast Canada to Venezuela! Radar and AIS integration make this thing your command center.
