Cartography is another item to consider prior to purchase of any chartplotter fishfinder combo unit. You may already own or be able to trade up on a certain brand of chart card.
The Raymarine C Series multifunction displays give you radar, chartplotting and fishfinder power in a single brilliant sunlight viewable display. Completely customizable, the Raymarine C Series can be a powerful single function display or a complete navigation system on a single screen: easy-to-use and easy-to-see.
NSS Sport Multi-function Displays are extremely easy to use, with simple menus and icons on the touchscreen that guide you to the information you need. The keypad includes “one-touch” buttons for immediate access to important functions such as the autopilot. Operation is intuitive and simple for everyone onboard. Not only is the NSS Sport an outstanding chartplotter and fishfinder, it’s a complete command center.
A number of newer chartplotter fishfinder units are capable of displaying AIS targets when connected to a receiver. This information is generally passed back and forth using a NMEA 0183-HS network. This is a 38400 baud network that is not compatible with the older slower 4800 baud NMEA 0183 system.
