The TM165HW delivers an ideal combination of power, sensitivity and coverage for bass, walleye, and inshore anglers looking to enhance their fishfinder’s performance. Traditionally, high frequency transducers provide the best resolution, but normally have a narrow beamwidth that limits the viewable area under the boat. The patent-pending, ceramic design enables the TM165HW to deliver an average beamwidth of 30° across the entire high frequency band of 150-250 kHz. The results are three times the total coverage and more fish revealed in a wider area under the boat than is possible with traditional non-Chirp transducers. In addition to providing vast bottom coverage, the wide beam enables excellent fish detection in the upper water column, an area missed by most narrow beam transducers. Airmar’s expanding series of wide beam transducers deliver large, crisp return images on the display with a noise-free, clear picture of the action below. The TM165HW is perfect for fishing boats up to 25 feet (8 meters).
