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.
