The new top of Humminbird's fast-growing electronics line seems capable, as deconstructing its model name suggests. SI means that the 957c, besides doing "normal" dual-frequency fishfinding, can push out a wide, 600-kHz swath whose returns build a photo-like "sonar image" of bottom structure up to "150 feet down and 240 feet to each side." Note the detail on that sunken bridge! "Combo" means that part or all of this eight-inch 480x800-pixel screen can be used as a chartplotter able to display any level of Navionics cartography, including Platinum with its processor pushing top-down photos, 3-D, etc. And "NVB," which brings this particular model up to a price of $2,200, indicates that it comes preloaded with all continental USA Gold charts and HotMaps Premium lake maps (a first, I think, in preloading). Like all the 900 Series Fishing Systems, this unit can network with other Johnson Outdoor Equipment, including Cannon downriggers. The series can also capture screens to a memory, either as still "snap shots" with GPS location or as continuous "video."
