It does have Monroe, Patoka, Boggs, and many other Indiana lakes. You can get Patoka in HD via a one time deal from Navionics...or any other lake that comes in HD. It is only good on PC's and has the following requirements: 1) Windows XP or Vista 2) DVD Drive
3)500 MB RAM 4) 1 GHz processor 5) Minumum 1024 x 768 16-bit display.
To view the availbale lakes go to www.fugwi.com/hme-lakelist.html
I think its a GREAT bargain for what you get and do with the maps. I am waiting to see the 3D views on my free HD download.....North KY Lake. The booklet says it comes in 3 ft. contour lines....maybe that will help find the right ledges
