GCV™ 20 Ultra HD Scanning Sonar Black Box with GT34UHD-TM Ultra HD Transom Mount Transducer
Add Ultra High-Definition Scanning Sonar to Your Compatible Chartplotter
The easy-to-install, networkable GCV 20 sonar black box allows you to redefine clarity and detail. Add any of the 3 GT34UHD transducer models to see stunningly clear Ultra High-Definition ClearVü and Ultra High-Definition SideVü scanning sonars — with frequencies ranging from 0.8 MHz (800 kHz) to 1.2 MHz (1,200 kHz) — to your compatible chartplotter. And you can share sonar images seamlessly across multiple networked chartplotters as well as networking Panoptix™ all-seeing sonar. It includes a max power output of 500 watts.
Ultra High-Definition ClearVü Scanning
This mode provides brilliant image clarity of structure and fish below your boat at greater depths than other high-frequency scanning sonars by putting more power on targets via a downward-facing element.
Ultra High-Definition SideVü Scanning
This mode delivers stunningly clear images of structure and fish off to the sides of your boat. This makes it easy to scout a fishing area quickly, because you can see everything the first time with such amazing clarity.
