Navionics Hotmaps

[Day Break]

Any of you guys use the hotmaps in your depth finder? It appears Lake Ontario coverage may be limitted based on what I am reading on the internet with a little shopping. Any advice for a first time user of the maps would be appreciated. I have a Hummingbird 917C combo unit on a 20' Lund. I also fish some lakes in the adirondacks and the eastern part of the state that appear to be included in the maps. They also have many levels of maps including a premium card. Cabelas has a 2010 map card on sale for $89.00 but I am a bit afraid to buy something that old.

Do not let the age of the card fool you.. On the Navionics premium east card. 2006 has more details on some of the lakes as opposed to the later model ones.Kentucky Lake is missing some areas on the 2009 and ups.
