Humminbird just came out with a 2D sonar unit with down imaging too. Black & white units that are very affordable. bbcboards.net is a good place to view both Humminbird & Lowrance sonar forums & be able to make your own opinion on which unit would suit you more. Both forums have some out standing images uploaded that you can view. Humminbird gets my vote for ease of use. I've owned Lowrance & every unit I've owned but 1 has given me problems & have been replaced with Humminbird & not a problem so far.
