I know some of you guy's that give GPS advice to guy's like me are getting pretty wherry of giving us tips and other helpful stuff on the subject, but I am real close to making the plunge, I am going to go with Hummingbird I have been a Eagle or Lowrance guy in the past but I'm going with Hummingbird this time.

Ok I read about things like (Navionics) (one card or two cards) ( Hotmaps) ( preloaded) and the built in Unimap ?? I read about them but find it hard to know what to do, I know I could spend the money and get it all, but I would like to know what some of you use to help me out .

Thanks in advance

Gary
