I have it on my Lowrance. If you are a river or lagre popular lake fisherman i would say yes it is good. There are a lot of smaller local lakes that are not on there ie: Cross creek. But for lake Erie and the local rivers you cant beat it. They come in so many different forms. the most expensive is not always what you need. I was going to get the top of the line card until I relized that i wouldnt need 1/2 of the coverage areas. you have to ask yourself how many bodies of water and where they are, then choose. its a good product. lots of info where things are such as attractions fuel hospitals and such. Good luck!
