The 997c SI is a high-end electronic fishfinder from the Humminbird company. Featuring an 8-inch widescreen color LCD display, this model utilizes 50-channel GPS connectivity to provide users with thousands of waypoints alongside additional route and track information for optimal water analysis. SideImaging advanced sonar technology uses sonic beaming to capture intricate structural detailing within a 500-foot radius of the unit, offering numerous view types to hone in on specific lifeforms. DualBeam Plus area cover boosting technology provides users with separate, side-by-side and consolidated views of multiple interest points, with split-screen zooming offered for tracking two zones at once. Freeze-framing enables GPS structure marking for singular focus on a single desired fish, with selective identification helping to minimize irrelevant data from registering within the device. The 997c SI also has the ability to record and still-capture sonar footage for later playback, incorporating TrueArch processing technology to preserve the most natural and realistic imagery. When fishing is complete, anglers can connect the unit to a computer via ethernet to upload and share their results with other Humminbird product owners to compare and discuss data through a social platform.
