The Furuno GP1670F represents the entry-level offering of Furuno’s fishfinder/chart plotter combo systems. It offers a lot of the advanced features found in the more expensive models. The unit is targeted at boaters who want the combination of accurate GPS/WAAS (Wide Area Augmentation System) performance and enhanced chart plotting and fish finding capabilities.
The GP1670F supports 600W or 1kW transducers and introduces a host of software features that enhance sonar output. Post-Processing Gain Control allows you to view changes to the gain setting immediately for all returns on the screen, making it easier than ever to dial in your fishfinder for local conditions. The White Line feature shows you fish lying on or near the bottom. The Bottom Discrimination feature provides information about the sea floor composition which is shown in four categories: gravel, mud, rock or sand. Additionally, the Furuno GP1670F comes with the Accu-Fish feature, which assesses the size of the fish. The unit can detect a 4-inch to 6-foot fish in depths of 7 to over 300 feet of water.
Providing crystal-clear images on the Furuno GP1670F is the TFT color LCD screen, which has a resolution of 640 by 480 pixels. Also, with 800 candelas per square meter, the device’s screen is rather bright. The diagonal size of the screen is 5.7 inches. The display is bonded to make sure that it does not fog up. The Furuno GP1670F is compatible with C-MAP 4D, a chart system from Jeppesen. It is useful for providing vector chart content and dynamic raster chart presentations. Also available from C-MAP 4D are 3D views, exclusive Easy Routing and satellite images.
