Humminbird 787C2 sonar GPS Combo
For 2007, Humminbird has released 2 new versions of the 787C2 combo. You now have your choice of an internal and external antenna, and you also have the choice of getting the unit with or without Navionics maps preloaded (HotMaps Premium 2006 and Navionics Gold for continental USA and Alaska). Or, the 787C will also work with optional Navionics Hotmaps Premium 2007 SD or the new Gold XL9 charts.
Additionally, these new units have the Humminbird AS-SYSLINK 10′ Y Cable option which allows you two connect two unit with only one GPS antenna. If you run Cannon Downriggers, the Humminbird AS-Cannonlink Downrigger Controller is compatible with the 787c as well.
Humminbird has done a really nice job with this unit.
