Furuno GP1971F 9" GPS Chartplotter CHIRP Fishfinder

The Furuno GP1971F is the 9-inch multi-touch GPS chartplotter / fishfinder combo from Furuno's compact display lineup. The product positioning is meaningful: serious recreational fishermen who want the Furuno fishfinder reputation (the company has built professional and commercial-grade marine sonar for decades and it shows in the algorithms) in a modern touchscreen package that fits a typical recreational helm. The GP1971F gives you the Furuno fishfinder DNA without the cost or complexity of the larger NavNet TZtouch class displays.

9-inch multi-touch LCD with the NavNet TZtouch2 interface. The 9-inch all-glass display uses the same multi-touch slide-out menu interface as the larger NavNet TZtouch2 series. Slide your finger down from the top to bring up Quick Pages (saved custom display modes that you switch with a single tap). Slide from the left to view customized Data Boxes (the data fields you want visible alongside the chart - speed, depth, heading, water temperature, etc.). Slide up from the bottom to adjust layer settings (chart layers, AIS overlay, radar overlay if connected). Slide from the right to access menu functions. Tap or double-tap with two fingers for screenshots and customized actions. Everything is contextual - the menu options change based on the current display mode, so you don't wade through irrelevant options to find what you need. The interface is meaningfully more intuitive than older button-driven Furuno displays, and the slide-out approach keeps the main display area uncluttered when menus aren't active.

Built-in dual-mode fishfinder. The GP1971F includes both a CHIRP fishfinder and a conventional 50/200 kHz fishfinder in the same unit. Why both: CHIRP is the modern high-resolution mode (sweeps a frequency band rather than transmitting a single frequency, gives meaningfully better target separation - two fish stacked vertically a foot apart show as two distinct returns instead of merging into one fuzzy blob). Conventional 50/200 kHz is the proven dual-frequency mode that's been the marine fishfinder standard for decades - 200 kHz for high-resolution shallow-water work, 50 kHz for deep-water penetration. Furuno's algorithms run both modes simultaneously on compatible transducers, so you get the best of both technologies on one screen.

600W and 1kW transducer compatibility. The GP1971F is compatible with both 600-watt and 1-kilowatt transducers. 600W is the typical recreational fishing transducer power - covers depths to roughly 1,500 feet in good conditions, suits inshore and nearshore offshore fishing. 1kW is the deeper-water option - covers depths to 3,000+ feet for true offshore deep-water fishing (tuna, swordfish, deep-water bottom fishing). The compatible transducer is sold separately and the choice depends on your fishing depth requirements.

ACCU-FISH fish size assessment. ACCU-FISH is Furuno's fish-target processing algorithm that estimates the size of individual fish targets by analyzing the return signal characteristics. The display shows fish icons with estimated lengths next to each target - so you don't just know there's a fish at 80 feet, you know it's roughly 18 inches versus 6 inches. This matters for tournament fishing (size estimation helps prioritize which targets to work) and for typical recreational fishing (knowing a school is keeper-size versus juvenile fish saves time). ACCU-FISH accuracy varies by species and conditions, but it's meaningfully better than no size estimation at all.

Bottom discrimination function. The GP1971F's bottom discrimination algorithm analyzes the return signal from the bottom and characterizes the bottom type (mud, sand, gravel, rocks, vegetation). Different fish species hold over different bottom types - bass on rock structure, walleye on gravel transitions, flounder on sand bottom. Bottom discrimination lets you identify the productive bottom types in your fishing area and target them efficiently rather than fishing over unproductive bottom for hours.

Internal GPS antenna - no separate antenna needed. The GP1971F has an internal GPS antenna (the antenna is inside the display housing, no external GPS antenna required). For boats with limited mounting real estate or owners who want to minimize the install footprint, the internal antenna is the right call. For boats where the helm location has metal obstruction overhead (a hardtop with metal reinforcement, an enclosed cabin with metal roof), an external GPS antenna may give better satellite reception - the GP1971F supports adding an external antenna in those cases.

C-Map 4D and Navionics chart compatibility. The GP1971F runs both C-Map 4D charts and Navionics charts via SD card - so you can choose the chart provider that has the best detail for your fishing area. C-Map 4D is the typical choice for offshore boats (good offshore detail, vector chart format that scales smoothly). Navionics is the typical choice for inland and inshore fishing (good lake and inshore coastal detail, proprietary depth and contour data). The unit ships without preloaded charts - chart purchase is separate by region and provider.

AIS receiver compatibility. Connect a separate Class B AIS receiver and the GP1971F displays AIS targets (commercial ships, AIS-equipped recreational boats) on the chart with course and speed vectors. Click an AIS target to see vessel name, MMSI, dimensions, and CPA / TCPA (closest point of approach / time to closest point of approach). For boats that operate in commercial shipping channels or in areas with heavy boat traffic, AIS display on the chartplotter is meaningful collision-avoidance information.

Wireless radar option (Furuno DRS4W 1st Watch). Pair the GP1971F with the Furuno DRS4W wireless radar dome for radar overlay on the chartplotter. The DRS4W is a 19-inch radar dome that connects via wireless rather than the traditional Ethernet cable from radar to display - simpler install, especially on retrofit applications. The wireless radar can also display on a connected smartphone or tablet via the Furuno wireless app, so you've got radar data on multiple devices around the boat. Note: the DRS4W radar is sold separately, not included with the GP1971F.

Autopilot control. The GP1971F connects to compatible Furuno autopilots via NMEA 2000 and provides waypoint navigation control - the autopilot follows the routes set on the chartplotter. For boats running both this Furuno chartplotter and a compatible Furuno autopilot, the integration is straightforward and the chartplotter becomes the primary route-planning interface.

NMEA 2000 connectivity. Standard NMEA 2000 marine network port for engine data, fuel sensors, environmental sensors, AIS receiver, autopilot, and other compatible NMEA 2000 components. The GP1971F displays the NMEA 2000 data on configurable gauge layouts. NMEA 0183 is also supported via a separate adapter for legacy sensor integration.

IP56 waterproof rating. The unit is rated IP56 - protected against dust ingress and against powerful water jets from any direction (handles wave splash, washdown, and rain without water intrusion). For helm-mounted installs that see direct exposure to the elements, the IP56 rating is the appropriate marine specification.

What's in the box. The GP1971F display, flush mount kit, gimbal mount bracket, power / data cable, NMEA 2000 cable adapter, basic install guide. Required separately: the transducer (600W or 1kW depending on your depth requirements), C-Map 4D or Navionics charts for your area, optional DRS4W wireless radar, optional autopilot.

Two-year limited warranty. Standard Furuno warranty terms apply. Service runs through the Furuno authorized service network.
