With this transducer, you gain reliable sonar performance across water columns, enabling accurate depth, speed, and temperature readings in real time. The dual-frequency capability lets you switch between broad-bottom scanning (77 kHz) and high-detail shallow readings (200 kHz). The 12° tilt design and robust plastic housing provide stable readings on boats with 8°–15° deadrise, while 500W of power and the 45°/15° beam widths deliver clear imagery and effective target discrimination. Simple 8‑pin integration keeps setup straightforward with compatible Garmin systems, and the depth, speed, and temperature data support smarter navigation and fishing decisions. Ideal for both deep-water exploration and shallow-water scanning, this transducer helps you fish smarter, navigate safer, and enjoy more time on the water.
