Add any of the 3 GT34UHD transducer models to see stunningly clear Ultra High-Definition 800 kHz ClearVü and Ultra High-Definition 1200 kHz SideVü scanning sonars 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 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.
