Location: Waukesha Wisconsin | Lowrance uses Navionics. http://www.navionics.com
Navionics has the Classic which is black and white, the gold which is for color units and HotMaps which is for inland lakes. The Classic and Gold is used by people fishing the Great Lakes. I use the LAKE MICHIGAN Navionics chip for Green Bay, Sturgeon Bay, Bay de Noc and Lake Winnebago. One chip has it all (the entire Lake Michigan plus Bago)
For the inland lakes I use their Wisconsin HotMaps. The chip has over 225 lakes on it.
It really depends on what company you go with for the GPS/Sonar. They each have their own supplier for mapping. I run Lowrance so I go with Navionics. If you'd look in all the boats at tournaments I'd say about 90% (just a guess) use Lowrance. I'm currently running the X15 and a global map 3000. It's over kill for the average fisherman. When I upgrade on next boat I'll be going to one of the color units. I'd speculate that in two years all you will see is color.
Hope this helps.
