The Humminbird 50-Channel GPS/WAAS receiver gives you lightning fast position fixes accurate within 2.5 meters. This receiver can be used in lower signal areas (compared to a AS GR16) and still maintain a position fix. It also has a faster Time to First Fix (TTFF). The receiver's dimensions are: 3.25" diameter, 1.5" high and comes with 20 feet of cable and has a 1"-14 thread count stem mountable with optional antenna stem (antenna stem not included).

I would call Humminbird and complain about the internal GPS not working properly. I apparently did that enough times that they sent me one for free to solve my problem Good folks.
