Step up to a 1kW thru-hull transducer without a fairing! The Airmar B164 transducer has taken its innovative Tilted Element technology to a higher power. Perfect for fast, trailered tournament sport fishing vessels that cannot have a high-performance fairing. The flush-mounted, bronze housing protrudes less than 6.35 mm outside your hull and can sit on trailer rollers and bunks with no damage at all. The ceramic array is tilted inside the transducer housing, giving you the perfect vertical beam with maximum energy on what is directly below your boat. 50/200 operating frequency. Temperature included.
