The 581i Combo features an ultra-high resolution, 16 level grayscale 640V x 320H 5" display, DualBeam PLUS sonar with 250 Watts RMS power output, and GPS Chartplotting with built-in UniMap.
The built-in UniMap covers the contiguous U.S.A. coastline and inland lakes and rivers at 30 meters per pixel resolution. On the coast, this clearly shows features as small as canals, and many coastal navigation lights. Inland, the UniMap features virtually all recreational lakes and rivers, plus hundreds of thousands of small lakes that don’t appear on other charts. In other words, your lake is likely to be there! The detail of these charts can be seen right on this page. With the UniMap, you have a chart virtually anywhere you travel in the United States.
