Airmar B619 – Through-hull bronze transducer 500W (77/200kHz) with tilted element (12°) – (8-pin)

The Airmar B619 Garmin transducer has a power output of 500W. It is designed for depth and temperature detection applications.

The Airmar B619 transducer uses a dual frequency of 77/200 kHz. This combination makes it versatile for various fishing and coastal navigation applications.

The Airmar B619 transducer provides accurate depth readings down to 274 meters (900 feet), making it suitable for coastal navigation and fishing.

This through-hull transducer provides depth and water temperature data. This information is essential for navigation and fish finding.

The 12° tilted element in the B619 transducer is designed to compensate for the hull deadrise angle (between 8° and 15°). This ensures the sonar beam is projected vertically downward, optimizing performance and accuracy of readings even on angled hulls.

The Airmar B619 transducer is supplied with a 9.14 m (30 ft) cable, making it easy to integrate with compatible Garmin systems.

The Airmar B619 transducer has a low-profile design. Once installed, only 5 mm (0.2 inches) of its housing protrudes from the hull, minimizing drag and impact on the boat’s performance.

The bronze housing of the Airmar B619 depth sounder provides increased durability, particularly for fiberglass and wooden hulls. It is more robust than plastic housings and specifically recommended for these hull materials.

The Airmar B619 transducer is suitable for use in saltwater and freshwater. For saltwater use, applying a water-based antifouling coating to the transducer face is mandatory.

The Airmar B619 transducer, with its bronze housing, is recommended for fiberglass and wood hulls. It is not suitable for metal hulls.

No, the Airmar B619 transducer, with its bronze housing, is not compatible with metal hulls. Installation on a metal hull would pose a risk of electrolytic corrosion.

The Airmar B619 transducer is equipped with an 8-pin connector, which simplifies its integration with compatible Garmin systems.

The Airmar B619 transducer is compatible with Garmin systems that support 500W dual-frequency (77/200 kHz) transducers and have an 8-pin connection port. It is recommended to verify specific compatibility with your Garmin device model.

The B619 depth sounder is a tilted-element depth sounder with a 12° tilt, making it suitable for compensating hull deadrise angles ranging from 8° to 15°. This ensures the sonar beam is vertically oriented toward the seabed.

For the transducer installation, you will need:

Safety glasses, dust mask, hearing protectionElectric drill (chuck size Ø 10mm or larger)Drill bit Ø 3mm or 1/8"Hole saw Ø 51mm or 2"SandpaperMild detergent or light solvent (alcohol)Marine sealant (suitable for below waterline)Cable tiesWater-based antifouling paint (mandatory in salt water)

For optimal performance, install the depth sounder in an area where water flows smoothly, with minimal bubbles and turbulence, especially at high speed. It must remain continuously submerged at all speeds, and its beam must not be obstructed by the keel or propeller. Choose a location away from interference sources (engine, other sounders, etc.) and with minimal drift angle.

For installing the Airmar B619 transducer, you will need to drill a 51 mm (2 inches) diameter hole in the hull. It is recommended to first drill a 3 mm (1/8 inch) pilot hole.

To ensure a watertight installation, apply a layer of marine sealant approximately 2 mm (1/16") thick around the flange and on the side of the transducer housing. The sealant must extend beyond the combined thickness of the hull, washer, and nut to ensure proper sealing in the threads and keep the nut in place.

Yes, the Airmar B619 transducer can be installed on a cored fiberglass hull. Specific instructions must be followed for this type of hull, often involving hole preparation with resin and fiberglass to seal the core and prevent water absorption.

Yes, applying a water-based antifouling coating on the transducer face is mandatory if the boat is used in saltwater. This helps prevent marine growth buildup that could affect the depth sounder's performance.
