Airmar B75H - Sondă traversantă bronz 600W CHIRP (130-210kHz) cu element înclinat (20°) + temperatură - (8 pini)

The Garmin Airmar B75H transducer is a 600 W through-hull CHIRP bronze transducer. It operates in the high-frequency band (130–210 kHz) and features a 20° tilted element. It provides depth and water temperature data via an 8-pin connector.

The Airmar B75H transducer operates on a high-frequency CHIRP band, ranging from 130 kHz to 210 kHz.

The B75H transducer is designed to measure water depth and water temperature.

The Airmar B75H transducer housing is made of bronze.

The Airmar B75H transducer comes with a 10-metre (33-foot) cable.

The beam width of the B75H transducer ranges from 15° to 9° across its high-frequency range (130–210 kHz).

Yes, the B75H transducer uses CHIRP technology. This technology provides superior target separation and improved resolution of seabed details compared to fixed-tone transducers.

The Garmin Airmar B75H transducer is designed to be compatible with Garmin systems featuring an 8-pin connector.

The bronze housing of the Airmar B75H depth sounder is recommended for fiberglass or wooden hulls. It must never be installed on a metal hull, as this could cause electrolytic corrosion.

The B75H transducer is a 20° tilted-element model. It is specifically designed to compensate for deadrise angles of hulls ranging from 16° to 24°, ensuring a vertically oriented acoustic beam for optimal performance.

No, a metal enclosure, such as the bronze B75H housing, must never be installed on a vessel with a positive ground system. This is a precaution to prevent electrolytic corrosion.

When installing the depth sounder, it is essential to wear safety glasses, a dust mask, and hearing protection to ensure your safety.

The size of the hole to drill depends on the type of hull:

For a fiberglass or wooden hull, a 70 mm (2-13/16") diameter hole must be drilled from the outside of the hull. For a cored fiberglass hull, a 70 mm (2-13/16") hole is required on the outside of the hull, and an 80 mm (3-1/8") hole on the inside of the hull.

The transducer must be installed in an area where water flows smoothly, with minimal bubbles and turbulence, especially at high speed. It must remain continuously submerged, and its beam must not be obstructed by the keel or propeller shaft. Avoid areas near water intakes or discharges, seams, fittings, or other hull irregularities that could disrupt water flow.

No, CHIRP transducers, such as the B75H, generate more heat than traditional transducers. It is crucial to install the transducer in a cool, well-ventilated location, away from the engine compartment or other heat sources, to prevent overheating that could lead to failure.

Yes, applying a water-based antifouling paint is mandatory in saltwater to prevent marine growth. Marine growth on the transducer can negatively affect sonar performance. Airmar certifies that applying the Foulfree coating to its transducers does not result in any loss of performance.

The arrow on top of the transducer must point toward the keel or the boat's centerline. This orientation is critical to align the internal element angle of the depth sounder with the hull's deadrise angle.

No, the transducer must always operate in water. Using the depth sounder in air can cause overheating, which may lead to equipment failure.

For the installation of the B75H transducer, it is recommended to use a high-quality marine sealant, specifically designed for use below the waterline, to ensure a perfect and durable watertight seal.
