Airmar B150M – prečna sonda iz brona 300W (95–155 kHz) z nagnjenim elementom (20°) + temperatura – (8 žil)

The Garmin Airmar B150M 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 within a CHIRP mid-frequency range from 95 kHz to 155 kHz, providing a total bandwidth of 60 kHz.

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

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

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

The bronze housing of the B150M transducer is recommended for fiberglass or wood hulls. It must never be installed on a metal hull due to the risk of galvanic corrosion.

The B150M transducer has a 20° tilted element, making it specifically suited 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 wood hull, drill the hole from the outside of the hull at 51 mm (2 inches). If the fiberglass hull is cored, the hole diameter on the inside of the hull is 60 mm (2-3/8 inches).

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

No. The B150M transducer’s Tilted Element™ design features a 20° tilted element inside the housing, which compensates for hull drift angle. This eliminates the need for an external fairing block, ensuring the sonar beam is aimed directly at the seabed.

The arrow on the top of the transducer must point toward the keel or the central axis of the boat. This orientation aligns the internal element angle of the transducer with the hull's drift angle.

The CHIRP depth sounder should not be installed 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, an angle finder, an electric drill, a 3 mm (1/8") drill bit, a hole saw (51 mm or 2" for external mounting, 60 mm or 2-3/8" for internal mounting on foam-core hulls), sandpaper, a mild detergent or weak solvent (such as alcohol), and marine sealant suitable for below the waterline. For fiberglass foam-core hulls, fiberglass cloth, 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 saltwater. It is important to use only water-based antifouling paints.

It is imperative to immediately check for 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.
