User Reviews about Humminbird 587ci 4.5-Inch Waterproof Marine GPS and Chartplotter with Sounder

Excellent Fish Finder but if you are buying this to also use as a GPS you might just want to re-think or be prepared to add another hundred dollars for the Navionics addition. Just a heads up to those looking more at the GPS side of the unit than the Fish Finder. -- Humminbird 587ci Rating

I was very happy once my husband had it installed, to see his expression. It really put his old one to shame.. and he is a guy who likes his gadgets.. So if he's happy its gotta be good. Also, Its also removable so you don't have to worry about someone snatching it. I do recommend that you purchase the cover so it don't get scratched.. -- Just what I was looking for..
