The FISH 4600 delivers powerful dual frequency performance on a high resolution (320 x 234 pixels) display.
It has numerous sounder display options including split and full screen zoom, A-scope and a choice of white, blue or black background. There's also a choice of color palettes to highlight bottom structure or a particular fish species.
When purchased with an optional fuel kit, the FISH 4600 will let you track and display fuel data on screen - another feature unique to Navman.
