DownScan™ Imaging Add a new dimension to echosounding. This high frequency imaging gives a life-like representation of the water column, the bottom and any structure. See fish, rocks, weeds and wrecks. SideScan Imaging See a panoramic view of the boat's echo history. Scan the water and bottom from both sides of the boat for a unique perspective, to locate targets faster. TrackBack™ Scroll back through the echosounder history to mark fish or structure that you just passed over, so that you can easily navigate back. Downscan Overlay Exclusive technology allows you to overlay DownScan imaging onto Broadband Sounder™ on the same display to clearly separate fish from structure.
