Wow I just never gave the GPS a thought for the boat speed.You guys are right. I have a Solix 12 Humminbird Never had any kind of fish finder on my boat before and the one I have now is still new in box. I cant believe that the teck people at Humminbird didn’t say hey you don’t even need the speed sensor with this unit. I’ll just send it back or something thanks for the help jim
