The Garmin GT34UHD-TM pairs with the GCV™ 20 sonar module to bring Ultra High-Definition scanning sonar to compatible chartplotters. Three transducer arrays — including a dedicated downward-facing element — produce sharp imagery of structure and fish both directly below and to either side of the hull. Operating across frequencies from 0.8 MHz to 1.2 MHz, this transom-mount transducer delivers detail that standard high-frequency scanning sonar simply can't match, whether you're working freshwater impoundments or saltwater inshore flats.
