Product DescriptionThe HOOK series combines the benefits of CHIRP sonar with built-in Broadband and DownScan Imaging fishfinder technologies to give you a clear and complete view of the underwater environment beneath your boat. Using the Lowrance HDI Skimmer transducer, these CHIRP sonars provide the capabilities to produce medium and high CHIRP sonar ranges. With these CHIRP sonar advantages, the HOOK series can more easily distinguish between baitfish and game fish targets, provide better target separation at greater depths, and mark fish clearly at faster boat speeds.
The HOOK-4 CHIRP DSI comes with DownScan Imaging that provides easy-to-understand, picture-like views of structure and bottom detail, as well as selectable, single-frequency Broadband Sounder capability. With the exclusive Lowrance DownScan Overlay feature, boaters can layer DownScan Imaging views onto CHIRP sonar or Broadband Sounder displays for a stunning presentation that separates and clearly exposes fish targets from surrounding structure. 83/200 kHz Broadband Sounder plus 455/800 kHz DownScan Imaging for depths to 1,000' (300' DSI).
This fishfinder chartplotter combo model comes with a highly accurate built-in GPS that includes a detailed US background basemap and a microSD card slot for map upgrades. You can also use your Insight Genesis custom maps created from your own sonar logs. This fishfinder chartplotter offers TrackBack for accessing multiple pages of sonar history, Advanced Signal Processing, and a convenient page selector menu with quick access to all features using one-thumb operation. The multi-window display lets you quickly choose from pre-set page layouts, including a three-panel view. NMEA 0183 connectivity. 500W RMS.
