Hummingbird GPS
I have always been a Lowrance GPS/Fish Finder user.. I'm making the switch to Hummingbird to pair it up with Ipilot TM. So my questions is which Hummingbird unit is better than the other. Currently I have been looking at the
Humminbird Helix 7 SI and the Humminbird HELIX 9 DI. Any insight is greatly appreciated..
