LX-9 Digital Sonar/Camera System 8″ LCD Dual Beam W/OSD Camera


Decades of advanced sonar engineering meet wicked underwater wizardry; virtual reality joins aquatic reality, and both live to tell their stories—all on the screen of the same high-powered device. The minds at MarCum Technologies unleash the new LX-9—a totally dynamic sonar / underwater viewing experience you’ve got to see to believe. With a panoramic 8-inch split-screen enabled LCD, you can play the interactive ice fishing game in sonar and live action modes, simultaneously. Another MarCum Technologies breakthrough, the LX-9 is the industry’s first sonar/underwater viewing system combo with an integrated digital video recorder (DVR). For the first time ever, anglers can compare sonar signals with live underwater video side-by-side, providing a “big picture” underwater analysis. Learn to read sonar like never before. Quickly distill pertinent structure, lure and fish details that yield potently effective fishing patterns. Plus, record what you see, upload your videos and let your hotspots go viral. The LX-9 operates with all of MarCum’s patented, classic features plus its trademark digital fish-finding dominance. System includes an integrated switchable dual beam transducer alongside a high-resolution color camera boasting SONY Super HAD II CCD optics and 75-feet of cable. Unit is easily transferable to a boat with use of an optional High-Speed Transducer. Abundant digital on-screen displays include camera depth, water temperature at surface and/or camera depth and relative camera direction. Advanced sonar feature list is immense, including user-defined Multifaceted Sonar Display and Dashboard, Sonar Footprint™ Technology and patented Infinitely Adjustable Zoom, Bottom Lock Zoom and Interference Rejection (IR). Includes MarCum’s Automatic Camera Panner and protective SnowShield.
