It would be nice if all the state lakes where re-mapped down to the foot! The state won't be shelling out that kind of cash, so it will be up to private companies to do so. Not too much structure in the lakes down here (a few exceptions such as Tetonka). I would venture to say that all of the Mankato area lake maps are pretty much the same as of now. It has very few Mankato area lakes mapped. I also have a Hotspots elite chip (present that came with my i-Finder). I would have welcomed the option to purchase one of LM chips. I don't know much about the LM, but they don't have much for southern MN lakes, and I can't use it in my Matrix. If you fish southern lakes around Mankato, I think this is really your only choice. I got my chip from Cabela's for $130 (after $20 coupon in the mail if you spent over $100). This year's premium chip as a ton more lakes (especially in my area). I think they may have been referring to last year's premium gold chip. Someone mentioned a $200 Premium Nav chip. Of course, this is nothing more that a simulation mode from sitting in my easy chair. The Matrix's larger screen makes a huge difference. You have to zoom in so close then you lose the bigger picture.

Ive used the HotMaps Premium Edition for several years but just noticed that Lac Seul is also listed under the Platinum Edition. Big Diesel, I have been playing with my Nav Premium chip on both my Matrix 97 and i-Finder H20. The Navionics North Edition (N) which covers the Upper Midwest also covers a few lakes in Canada including Lac Seul.
