AIRMAR B619 20° tilt is a bronze thru-hull transducer that delivers stable performance at high speeds and is an excellent choice for boats with fiberglass or wood hulls. The transducer is designed for vessels with a hull deadrise of 16–24 degrees, where the tilted element ensures a correct sounder beam angle without the need for a fairing block.
With a power output of 500 W and dual-frequency 77/200 kHz, it achieves a good balance between depth range and detailed target separation. At 77 kHz, you get better bottom tracking at greater depths, while 200 kHz provides sharper rendering in shallower water. The maximum depth of up to 900 ft makes the B619 suitable for both coastal navigation and more open waters.
The 8-pin connector ensures compatibility with a wide range of sonar systems. The transducer kit comes with installation instructions, which must be followed closely for proper mounting and to avoid damage to the hull and equipment. Do not use on metal hulls.
