Furuno GP1871F 7 GPS/Chartplotter/Fishfinder 50/200, 600W, 1kW, Single Channel & CHIRP

The Furuno GP1871F is a 7-inch multi-touch GPS chartplotter and fishfinder with CHIRP power options from 300W to 1kW, conventional 50/200kHz sonar support, and a Worldwide Basemap. No transducer is included, so this unit suits buyers who want to select a Furuno sounder for their hull and fishing depth. Wireless radar connection, RezBoost, and ACCU-FISH add useful system features.

Key Features

- 7-inch multi-touch widescreen LCD – Provides a compact display for charting and fishfinding.
- 800 x 480 resolution – Shows essential chart and sonar information while keeping the installation small.
- CHIRP from 300W, 600W, or 1kW plus 50/200kHz sonar – Allows the sounder setup to match the selected transducer and power requirement.
- Wireless radar connection – Provides a listed connection path for compatible Furuno radar equipment.
- RezBoost and ACCU-FISH – Adds listed Furuno processing and fish-size estimation functions to the sounder platform.

Who Is This For?

This model suits small fishing boats, coastal skiffs, and cruisers that want Furuno navigation and flexible sonar power in a 7-inch touchscreen. It is a good fit for buyers who already understand their transducer and sounder requirements.

It is not ideal for someone seeking a complete ready-to-fish bundle because the transducer is not included. The Worldwide Basemap also does not provide the same regional detail as a package with preloaded coastal or inland charts.

Compatibility

Confirmed features include a Worldwide Basemap with C-MAP 4D support, wireless radar connection, CHIRP and conventional 50/200kHz sonar support, RezBoost, and ACCU-FISH. The supplied information does not identify compatible transducer models, NMEA 2000, NMEA 0183, autopilot, or specific radar models. No named incompatible system was provided; verify Furuno accessory and network requirements before installation.

The GP1871F is the flexible choice for buyers who want to select the Furuno transducer and sounder power rather than accept a fixed bundle. Its CHIRP range up to 1kW and conventional 50/200kHz support cover several fishing applications, while the Worldwide Basemap keeps the unit ready for basic reference mapping. The trade-off is that detailed regional charts and the transducer must be added or confirmed separately.
