humminbird 787 c2 (now with sidescan) have had it for a year now. awsome little unit. clear and intuitive. I am a big support of companies with good customer service. Right now i am having a problem with the gps antenna or connection or something. As long as you are within the year warranty you send it to them the fix it or replace it and send it back total round trip 9 days max.
No questions asked. Its a perfect striper finder

finds blues sometimes too

. You could probably get last years model pretty cheap now since they are pushing the sidescan like it's going out of style.
oh yea, the navionics chip is a must.
