Summary: We purchased this Humminbird fish finder as a gift for a friend who lives a good distance from us so we couldn't go fishing with him to see it work but his feedback to us is that it works great and he is very pleased with it.
Summary: I upgraded to the 788ci HD DI from the the 597c I purchased in 2011 for almost the same price. What a difference three years make! This unit does everything they say is does. The down imaging is amazing to watch and a power tool. I highly recommend this unit.
Summary: So far I have been using it as an ice unit, and it works great for GPS and fish finding. I haven't been able to test down imaging yet. I'm not sure the color feature is much better than mono but I've only used it six times so it may grow on me.
Great reputation,will use next year.Exceptional buy.
