Personally I would go with the 14XG, but thats just me. More Great Lakes coverage from the others. You will get more inland coverage with the Premium Hotspots. It looks to have most of Michigan (along with other states) covered pretty well. You will have to go to the website to see the list of lakes covered. There are MANY other maps on here that are HD (some with 1 foot contours). as a general rule, these maps are exactly like the HotSpots maps you can purchase in paper form. Includes US portion only of the Great Lakes, Lake Champlain, Finger Lakes, Ohio River, Cumberland River, Kanawha River, Allegheny River, Green River, Illinois River, Missouri River, Tennessee River, Mississippi River, Arkansas River, Green River, Tennessee-Tombigbee Waterway and entire Gulf of Mexico. You have some choices depending on where you will be needing coverage.Įntire Great Lakes, St Lawrence and the Canadian Maritimes, including Lake of the Woods, Rainy Lake, Lake Champlain, Trent Severn Waterway, Ottawa River, Rideau Waterway and the Finger Lakes. The iFinder series is limited to the Navionics Gold chips.
