Step up to a 1kW transducer without a fairing! The B164 is a tilted element transducer perfect for fast, trailered, tournament sportfishing vessels that cannot have a high-performance fairing. The flush-mounted, bronze housing protrudes less than 6.35 mm (0.25") outside your hull and can sit on trailer rollers and bunks with no damage at all. The ceramic array is tilted inside the housing, giving you the perfect vertical beam with maximum energy on what is directly below your boat. B164 transducer provides depth and temperature data. 50/200 kHz.
