Canandaigua Minnkota / humminbird and follow the contour feature for Canandaguia Lake

[Paul K]

What mapping card has the needed 1 foot contours so I can use the Follow the Contour mode with my Minnkota Terrova and my Humminbird Helix 9 on Cananadaguia Lake?  I have the Lake Master sd card and it works on Lake Ontario but Canandaguia Lake seems to not be one of the lakes it shows.

Yeah for some reason I don't see canandaigua lake listed
