Airmar B75H - þversónarþráður úr bronsi 600W CHIRP (130-210kHz) með hallandi þátt (12°) + hitastig - (8 stiftur)

The Airmar B75H transducer operates across a high CHIRP frequency range from 130 kHz to 210 kHz. This provides a total bandwidth of 80 kHz for precise detection.

The Airmar B75H transducer provides simultaneous depth and water temperature data.

Under optimal conditions, the Airmar B75H transducer, with its 600W power output, can reach depths up to 214 meters (700 feet).

The Airmar B75H transducer housing is made of bronze. The acoustic radiating surface is made of urethane.

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

The CHIRP high frequency of the B75H (130-210 kHz) is specifically suited for enhanced detail and target separation. Its narrow beam (ranging from 15° to 9°) is ideal for locating fish near underwater structures such as wrecks and reefs, as well as distinguishing baitfish schools from gamefish at mid-range depths.

The Airmar B75H transducer features a 12° tilted ceramic element. This angle compensates for hull deadrise angles ranging from 6° to 15°, ensuring the sonar beam is directed vertically.

The bronze housing of the B75H depth sounder is recommended for fiberglass or wooden hulls. It must never be installed in a metal hull due to the risk of electrolytic corrosion.

The transducer must be installed in a location where water flows smoothly, with minimal bubbles and turbulence, and where it will remain continuously submerged. The beam must be clear of the keel or propeller shaft. It is also crucial to keep it away from interference sources (propellers, engines, other sonars) and to mount it in a cool, well-ventilated area away from the engine compartment to prevent overheating. The arrow on the top of the transducer must point toward the keel or the boat's centerline.

CHIRP transducers generate more heat than traditional transducers. To prevent overheating and failure, the Airmar B75H transducer must always be used in water and must not be installed in the engine compartment or any other hot area. It should be mounted in a cool, well-ventilated area away from the engine.

It is imperative to immediately check for any leaks once the boat is launched. Do not leave the boat unattended for more than three hours, as even a small leak can lead to significant water accumulation.

You can apply a Foulfree coating to your transducer. This non-toxic, durable, and ultra-smooth coating, certified by Airmar, prevents marine fouling from adhering to the surface without affecting transducer performance. A single application can protect the transducer for up to two years.

The Airmar B75H transducer is designed by Airmar specifically for Garmin systems. However, exact compatibility will depend on your Garmin fishfinder or display model and its high-frequency CHIRP capabilities, as well as its 8-pin connector. It is recommended to check your Garmin device specifications to confirm compatibility.

The Airmar B75H transducer is equipped with an 8-pin connector, compatible with the corresponding Garmin systems.

No, the bronze housing of the Airmar B75H transducer must never be installed on a metal hull. This would cause electrolytic corrosion. This model is recommended only for fiberglass or wooden hulls.

The Airmar B75H transducer produces a narrow beam with a width ranging from 15° down to 9°. This feature is particularly effective for precise fish detection near structures and target discrimination.

Yes, it is important never to pull, carry, or hold the transducer by its cable. This could sever internal connections and damage the transducer.
