Lowrance ELITE-4X HDI Fish finder with 50/200+455/800KHz transom mount transducer. The Elite-4X is an easy-to-use 4.3-inch color fish finder with Hybrid Dual Imaging that combines Broadband Sounder with Down Scan Imaging technology and a super-bright, LED-backlit color display. The compact Elite-4x HDI combines a super-bright, LED-backlit color display with a full selection of today"s top-selling fish finder features that are easy to access and operate -- all at a surprisingly affordable price. The high-resolution, 4.3-inch, color LED-backlit display has 70% more pixels and 36% more usable screen area than previous Elite-4 series displays. Exclusive Hybrid Dual Imaging (HDI) combines Broadband Sounder plus Down Scan Imaging to give you the power of two award-winning technologies combined to provide the best possible view beneath your boat. Down Scan Overlay technology overlays Down Scan Imaging onto Broadband Sounder, and Advanced Signal Processing (ASP) reduces the need to manually adjust settings to see fish, structure and bottom detail more clearly. The TrackBack feature reviews recorded sonar history including structure, transitions or fish targets, and the new easy-to-use page selector menu gives you quick access to all features using one-thumb operation. The Multi-Window Display lets you quickly and easily choose from pre-set page layouts and includes a three-panel view. All this is supported by the Lowrance Advantage Service program. Dimensions: 6.6"H x 3.8"W x 2.2". Warranty: One year parts and labor. In the box: Elite-4X HDI, transom mount transducer, mounting bracket, power cord, owner"s manual.
