Featuring a LED backlit 4.3-inch color display, the HOOK-4x is powered by high-performance Broadband sonar with Advanced Signal Processing (ASP), excellent target separation and superior noise rejection, making it easier to see baitfish and gamefish targets. It features a built-in water temperature sensor and supports 83 Mid and 200kHz High frequencies, allowing you to select the frequency that works best with current water conditions.

KEY FEATURES
LED-backlit 4.3-inch color display with detailed 480 x 272  resolution that’s easy to see in full sunlight and from wide viewing angles Broadband Sounder™ detail easily identifies fish targets, bottom contour, structure detail, bottom hardness, thermoclines and more
Advanced Signal Processing (ASP) reduces the need to manually adjust settings to see fish, structure and bottom detail more clearly
Dual-frequency 83 Mid or 200 kHz High operation helps maximize the view beneath your boat
83 kHz Mid sonar operation provides up to 60 degrees of conical coverage, which is ideal for displaying largest fish arches and searching large area
200 kHz /high frequency provides up to 20 degrees of conical coverage for enhanced fish-target separation and lure-tracking – ideal for drop-shotting techniques
Pages button allows the user to quickly switch between 83 kHz and 200 kHz sonar frequency views
Fish I.D. displays fish icons instead of fish arches to help identify fish targets. Includes track and alarm options
Dedicated quick keys allow the user to zoom up to four times the standard view and focus on key fishing areas
Power button doubles as backlight control to adjust for daylight or nighttime fishing situations
Patented Skimmer® transducer with built-in water-temperature sensor can track bottom up to 75mph
Easily adjust the viewing angle or disconnect and store with the quick-release, tilt and swivel bracket
Supported by Lowrance Service program
