Airmar B150M – Bronze Through-Hull 300W (95-155kHz) CHIRP Sonde with 12° Tilt Element + Temperature – (8-Pin)

This CHIRP transducer operates across a mid-frequency range from 95 kHz to 155 kHz. This 60 kHz bandwidth provides extended coverage for fish detection.

Yes, the Airmar B150M transducer is equipped with an integrated water temperature sensor, providing real-time temperature data.

The B150M transducer, with its 300W power, can reach maximum depths of 183 meters (600 feet) under optimal conditions.

The Airmar B150M transducer has a beam angle ranging from 26° to 17°, which improves target detection beneath the boat.

The Airmar B150M transducer housing is made of bronze, a material recommended for fiberglass or wooden hulls.

The B150M's CHIRP technology offers several advantages:

High-resolution sonar images.Improved target separation compared to fixed-frequency transducers.Better detection of fish near structures.Ability to identify haloclines and thermoclines.An improved signal-to-noise ratio for finding fish and tracking the bottom at high boat speeds.

Thanks to its slanted element design, the B150M transducer protrudes by only 5 mm (0.19") below the hull, minimizing drag.

The B150M depth sounder is recommended for boats up to 8 meters (25 feet) and is compatible with all propulsion types. It suits fiberglass or wooden hulls, whether displacement, planing, or stepped hulls.

The Airmar B150M transducer, with its bronze housing, is specifically recommended for fibreglass or wooden hulls.

The B150M sounder, featuring a 12° tilted element, is designed to compensate for hull deadrise angles between 8° and 15°. This ensures the sonar beam is directed straight down, optimizing echo returns.

No, installing a bronze housing, like the B150M’s, on a metal hull is strongly discouraged. This would cause electrolytic corrosion.

The Airmar B150M transducer is fitted with an 8-pin connector, ensuring connection to your compatible Garmin equipment.

Yes, the B150M transducer is compatible with all propulsion types, making it versatile for various boat configurations.

For the B150M transducer installation, a 51 mm (2") hole must be drilled from the outside of the hull. For cored fiberglass hulls, a 60 mm (2-3/8") hole is required from the inside of the hull.

During installation, the arrow on the top of the transducer must point toward the keel or the centerline of the boat. This aligns the internal transducer element angle with the deadrise angle of your hull.

For optimal performance, choose a location where:

Water flows smoothly under the hull, with minimal bubbles and turbulence.The transducer is continuously submerged in water.The transducer beam is not obstructed by the keel or propeller shaft.The location is away from interference sources (propellers, machinery, other sounders, cables).For CHIRP sounders, the location is cool and well-ventilated, away from the engine, to prevent overheating.

No, it is critical to always operate the CHIRP transducer in the water. Operating it in air can cause the transducer to overheat, potentially leading to failure.

No. The B150M’s 12° tilted element design compensates for hull deadrise, eliminating the need for a fairing block. It also reduces underwater protrusion.
