I have been a big Furuno fishfinder fan since the beginning, and I’m not the only one. Their echo sounders have won so many industry awards over the years that I’ve lost count; their gear is that much a step ahead of competitive offerings. Every one of my 13 MarCeeJays over the past four decades has been equipped with a Furuno echo sounder and they have all helped me and my charter customers find and catch a lot of fish. My next boat will also sport a Furuno color sounder and in all probability, it will be one of these two units that we are going to discuss in more detail in this week’s review.
The GP1670F incorporates a powerful 600W/1kW Furuno Fishfinder and introduces a host of advanced features. 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, while the White Line feature shows you fish lying on or near the bottom at a glance. Furuno's Bottom Discrimination feature enables the unit to indicate if a major component of the bottom is mud, sand, gravel, or rocks. The Bottom Discrimination function provides you with valuable information to locate rich fishing grounds while boosting your catch of the day. Plus, in order to assess individual fish size, the echo strength from the fish can be computed and turned into fish size display on the screen.
