You will not be disappointed with a Humminbird! I have a plotter that I am very happy with. Gus and Bud have combo units that they like very much! Gus is pretty much of a Humminbird guru. No surprise there. Maybe he will help you out.

Gus,
Thanks for all the info you sent directly to me. I'm working on this information.
Again, Thanks
