Airmar B150M – sondă transversală din bronz 300W (95-155kHz) cu element înclinat (20°) + temperatură – (8 pini)

The Garmin Airmar B150M transducer is a 300W bronze through-hull transducer. It uses CHIRP technology over a mid-frequency range of 95-155 kHz. It features a 20° tilted element to compensate for hull drift angle and provides depth and water temperature data. It is equipped with an 8-pin connector.

The B150M transducer operates on a CHIRP mid-frequency range from 95 kHz to 155 kHz, providing a total bandwidth of 60 kHz.

Under optimal conditions, the Airmar B150M transducer can reach a maximum depth of 183 meters (600 feet).

Yes, the Airmar B150M transducer is equipped with a fast-response water temperature sensor.

The B150M transducer offers a beam width ranging from 26° to 17° depending on the frequency used.

The bronze housing of the B150M depth sounder is recommended for fiberglass or wooden hulls. It must never be installed on a metal hull due to the risk of electrolytic corrosion.

The B150M transducer is designed with a 20° tilted element, making it specifically suitable for hulls with a deadrise angle between 16° and 24° at the mounting location.

No, the Airmar B150M transducer has a bronze housing and must never be installed on a metal hull. This would cause electrolytic corrosion.

The Airmar B150M transducer is equipped with an 8-pin connector, compatible with Garmin devices.

For a fiberglass or wooden hull, the hole diameter to drill from the outside of the hull is 51 mm (2 inches). If the fiberglass hull is cored, the hole diameter for the inside of the hull is 60 mm (2-3/8 inches).

On a planing hull sailboat, the depth sounder must be mounted at the very rear, on or near the centerline, and well within the first set of lifting strakes. This ensures the transducer remains in contact with the water at high speed. The starboard side of the hull, where the propeller blades move downward, is generally preferred.

No, the Tilted Element™ design of the B150M transducer, with its 20° tilted element inside the housing, compensates for the hull’s drift angle. This eliminates the need for an external fairing block, ensuring the sonar beam is directed straight to the seabed.

The arrow on top of the depth sounder must point toward the keel or the centerline of the boat. This orientation ensures the internal element of the depth sounder aligns with the hull’s drift angle.

It is not recommended to install the CHIRP transducer in the engine compartment or any other hot area, as the transducer could overheat and fail.

For installation, you will need safety glasses, a dust mask, hearing protection, a protractor, an electric drill, a 3 mm (1/8") drill bit, a hole saw (51 mm or 2" for exterior, 60 mm or 2-3/8" for interior of foam-core hulls), sandpaper, a mild detergent or weak solvent (such as alcohol), and marine sealant suitable for below the waterline. For foam-core fiberglass hulls, fiberglass cloth and resin or a cylinder, wax, tape, and casting epoxy may also be required.

Yes, applying a water-based antifouling paint is mandatory on the depth sounder if the boat is used in salt water. It is important to use only water-based antifouling paints.

It is imperative to check immediately for any leaks when 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.
