Furuno GP1971F – 5.7-Inch GPS/WAAS Chartplotter with CHIRP Sonar

The Furuno GP1971F combines a 9-inch wide touchscreen with built-in GPS, WAAS, single-channel CHIRP, and conventional 50/200kHz sonar. It is a chartplotter and fishfinder for coastal boats and center consoles that want flexible sonar power without moving to a large MFD. C-MAP 4D support provides chart options, while NMEA 2000 and NMEA 0183 support network connections.

The 40-225kHz CHIRP range gives more flexibility than a fixed-frequency sounder, and the 300W, 600W, or 1kW output can be matched to the chosen Furuno transducer. The built-in 72-channel GPS with WAAS supports routes and waypoint storage, while ACCU-FISH and RezBoost help interpret returns. Structure scanning is not listed, so this unit is better for conventional fishfinding and navigation than for SideScan or 3D imaging.

Key Features

- 9-inch wide multi-touch color LCD – Provides a practical chart and sonar workspace.
- 40-225kHz single-channel CHIRP – Gives broad frequency flexibility for conventional fishfinding.
- 300W, 600W, or 1kW output – Lets the sounder match the selected transducer.
- 72-channel GPS with WAAS – Supports navigation and waypoint work.
- ACCU-FISH and RezBoost – Adds fish-size estimation and sonar image processing.

Who Is This For?

This Furuno GPS fishfinder suits coastal fishing boats, center consoles, and cruisers that want GPS and CHIRP sonar in one 9-inch display. It is not ideal for buyers seeking SideScan, RealVision 3D, or a transducer-included package; the sensor must be selected separately.

Compatibility

Confirmed features include C-MAP 4D, NMEA 2000, NMEA 0183, built-in 72-channel GPS with WAAS, 10-pin Furuno transducer connection, and wireless radar connection through WiFi. The supplied information does not identify specific radar, autopilot, Garmin, Raymarine, Simrad, or transducer models. No named incompatible system was provided.

The GP1971F is the balanced Furuno choice for GPS and conventional CHIRP sonar in a 9-inch display. Its trade-off is sonar scope: it does not list SideScan or 3D imaging, but it offers flexible power and frequency selection. Choose it for a traditional Furuno chartplotter fishfinder, not for a structure-scanning system.
