The 581 is a $300 unit, 2D/DI/GPS. Not the best, but it was what I can afford. I stayed away from the Lowrance units as they have no 2D sonar on the elite 4 series, and the elite 7 is out of my price range. I'm going to give this one an on-the-water shot as soon as I can, and return it if it isn't up to snuff.

I do like the menu system and ease of use, so it's not all bad. It is just that my $80 Fisheasy 240 has a much better screen than a $300 unit.
