Map Chip for Humminbird

[MacDaddy]

Can anyone recommend a map chip covering Lake "O" at least the Niagra and orleans County region with depth contours. Humminbird 858C.

I own a Garmin BlueChart Data Card for my HumminBird. It covers a little of Erie and all of Lake O to Montreal. Really like it! Label markings are: 010-C0033-00

Lake Ontario to Montreal

Found it very effective by using the zoom-in after reaching the general area to fish. More zoom=greater detail of bottom contour. Has allowed me to follow bottom contours while targeting walleye on Erie (west end out of Buffalo).

I am running the Navionics Platinum Plus, but for fishing I hear the Fishing Chip for Lake Ontario is better and shows contours better. The Platinum Plus is great for navigation and coming into new harbors.
