GCV™ 20 Scanning Sonar Black Box

with GT34UHD-TM Transducer

See the stunning difference in clarity between standard scanning sonar on the left and Ultra High-Definition ClearVü scanning sonar on the right.


Includes GT34UHD-TM Transducer

Clarity and detail are redefined with the Ultra High-Definition scanning sonar system. Using an easy-to-install, networkable GCV 20 sonar black box with an included three-array GT34UHD transducer, now you can get scanning sonar images in ultra high-definition. You see everything below and off to the sides of your boat in amazingly sharp, crisp detail.


Ultra High-Definition ClearVü Scanning

This sonar system 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

See 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.


Share Sonar Images

You can share your Ultra High-Definition scanning sonar images seamlessly across multiple networked chartplotters. You can also add optional Panoptix all-seeing sonar to your networked sonars.
