Everyone knows that Humminbird has been leading the way with Side-Imaging Fish Finders for years now. The Humminbird 997 model has always been a great tool for fishermen and real trouble for gamefish. For 2010 the 997 has been replaced with the new Humminbird 998c SI Combo (see the list of new features below). Just look at the picture and you can’t help but fall in love with this thing. A nice big screen and great high definition detail. What more could you ask for? And all this for less than $2000. Now THAT’s a deal!
