Re: Hummingbird Fishfinders & GPS
If the Humminbird is GPS ready- it means that it is most likely only capable of being a trackplotter only. Humminbird has various models that are of course also chartplotters- some have internal antennas and others require an external. Humminbird sells that external GPS receivers for about $100 as stated or if you have the right hand held GPS, you can capture it's output. The handheld GPS needs to be data output capable (NMEA 0183). Many GPS manufacturers have cradles with data cables that will work. Humminbird sells an interface cable that will work with many of the hand helds. BUT, the easiest way to go is with Humminbirds external receiver. Or, but a Humminbird unit with an internal receiver. Those units will have an "i" in their model designation.
