This 1kW transducer makes 600W fishfinders perform like more powerful units, especially at 50 kHz. The transducer uses Airmar's unique ceramic-element construction, which results in more narrow beams that clearly distinguish individual fish and bottom fish from their habitat at depths down to 2, 200'. Recommended for sport fishing boats at least 26' in length and small to mid-size commercial fishing boats. Bronze construction withstands the corrosive elements in marine environments. Includes temperature sensor and transducer ID option.
