Humminbird 797 fish finder/gps

[scrodycat]

I have been looking pretty seriously at giving up my old lorance, and dropping a bit of cash down on the humminbird 797 model. I was just curious if any one has used this device? It does have the side imaging which is very impressive. Don't realy know if its worth the extra $300.00 or so to move up from the 787 model. If any one has some insight on this impressive unit I would sure like to know.

Also maybe some help on explaining the importance of such an expensive device to my wife.
