For boats over 25 feet, consider 9 inch and larger displays for visibility from various positions.

Touchscreen versus keyed interface is another important choice. Touchscreens offer intuitive operation and are easier for many users, but keyed interfaces provide tactile feedback that works better in rough conditions or when wearing gloves. Some boaters prefer the reliability of buttons, especially in saltwater environments where spray and moisture can affect touchscreen responsiveness.

Chart compatibility matters depending on where you boat. Navionics and C-MAP are the two major chart providers, and both offer excellent coverage. However, some units come with only coastal or only inland charts, so consider your typical boating areas. If you boat in both coastal and inland waters, look for units that offer both chart types or the ability to add additional chart cards.

NMEA networking capability becomes important if you plan to integrate your chartplotter with other marine electronics. NMEA 2000 is the modern standard and provides plug-and-play compatibility with most modern marine electronics. If you want to display engine data, connect to autopilot, or integrate with radar, ensure your chosen chartplotter has NMEA 2000 support.

Fishfinder integration is crucial for anglers. Most modern chartplotters include sonar capability, but the quality varies. CHIRP sonar is now standard and provides better target separation than traditional sonar. For serious anglers, look for units with SideScan and DownScan capabilities, which provide detailed views of structure and fish to the sides and beneath your boat.

Consider future expandability. A chartplotter that supports radar, satellite weather, or live sonar might cost more initially but can save money down the road if you decide to add those features. Look for units that support the latest sonar technologies, especially if you’re interested in live sonar, which is rapidly becoming popular among serious anglers.
