Airmar B619 – Bronzová průchozí sonda 500W (77/200kHz) s nakloněným prvkem (20°) – (8 pinů)

The Garmin Airmar B619 transducer is a 500W through-hull bronze transducer operating at 77/200 kHz frequencies. It features a 20° tilted ceramic element and is designed for depth and temperature detection. Its low-profile design minimizes drag, protruding only 5 mm (0.2 in) from the hull.

The B619 transducer has a power output of 500W and operates on two frequencies: 77 kHz and 200 kHz.

The Garmin Airmar B619 transducer can provide reliable data down to a maximum depth of 274 metres (900 feet).

The B619 transducer offers a 45° beam angle at 77 kHz and a 15° beam angle at 200 kHz, providing coverage suited to varied navigation and fishing conditions.

Yes, the Garmin Airmar B619 transducer is designed for depth and water temperature detection.

The Airmar B619 transducer, with its bronze construction, is ideal for fiberglass and wood hulls.

The B619 transducer integrates a 20° tilted element, making it specifically suited for hulls with a deadrise angle between 16° and 24°.

No, the B619 transducer with its bronze housing must never be installed on metal hulls. This is due to the risk of electrolytic corrosion, which could damage both the transducer and the hull.

The Garmin Airmar B619 transducer is equipped with an 8-pin connector, ensuring direct integration with compatible Garmin systems.

The B619 transducer is designed for direct integration with compatible Garmin systems. It is recommended to verify specific compatibility with your Garmin display or fishfinder model.

For installation of the B619 transducer, a hole of Ø 51 mm (2 inches) must be drilled through the outer hull.

The B619 transducer’s Tilted Element™ technology compensates for the boat’s deadrise angle. This ensures the sonar beam is vertically oriented, delivering more accurate depth readings and stronger echo returns, even at high speeds.

For optimal performance, the transducer must be installed in an area where the water flow under the hull is smooth, with minimal bubbles and turbulence, especially at high speed. Avoid areas in line with water intakes, discharges, behind strakes, fittings, or any hull irregularities. The beam must not be obstructed by the keel or propeller shaft.

Yes, several precautions must be observed:

Never install the bronze transducer on a metal hull to avoid electrolytic corrosion. Ensure the transducer’s tilt angle (20°) matches the hull’s deadrise angle at the mounting point. Apply a suitable marine sealant for below-waterline applications. Never pull, carry, or hold the transducer by its cable. Immediately check for leaks once the boat is launched.

The Garmin Airmar B619 transducer can be installed on hulls with a maximum thickness of 64 mm (2.50 inches).

Thanks to its low-profile design, the B619 transducer protrudes only 5 mm (0.2 inch) outside the hull, minimizing drag.

During installation, it is crucial that the arrow on top of the transducer points toward the keel or the centerline of the boat. This ensures the internal element's angle is correctly aligned with the deadrise angle of your hull for accurate readings.

For installation of the B619 transducer, a minimum vertical clearance of approximately 95 mm (3-3/4 inches) is required inside the hull to accommodate the transducer body and allow for nut tightening.

Before installation, the area around the hole, both inside and outside the hull, must be sanded and cleaned. This ensures proper adhesion of the marine sealant. Any petroleum residue must be removed with a mild detergent or a weak solvent (such as alcohol) before sanding.

Yes, the bronze construction of the B619 transducer makes it particularly suitable and resistant to marine environments, including salt water. For installations in salt water, applying a water-based antifouling layer is mandatory to maintain its performance.
