Airmar B150M 12° Tilted Element Transducer for Fish Finder

The B150M blends steady shallow-water performance with dependable deep-water accuracy, making it a versatile choice for freshwater, inshore, and coastal fishing. Operating in the 95–155 kHz medium-frequency band, it delivers clear targets from near the surface down to about 183 m (600 ft), with a depth reading and fast-response water-temperature sensor that keeps you informed in real time.

Designed with Tilted Element™ technology, this transducer places the ceramic element at a fixed angle inside the housing to compensate for hull deadrise. The result is a beam directed straight down, maximizing echo returns and yielding more accurate depth readings even when speed is a factor. The 12° tilt version is specifically engineered for hull deadrise ranges around 8° to 15°, ensuring reliable performance on a wide variety of boats.

What makes the B150M unique

Key strengths that set this transducer apart include:

• Fixed 12° Tilted Element for optimized down-looking performance across typical hull deadrise (8°–15°). This alignment minimizes beam misdirection and improves target clarity underwater.
• Depth and fast-response water-temperature sensor keeps you aware of both depth and water conditions in real time, helping you choose the right lure and technique for changing currents.
• 300 W power rating with depth performance to 183 m (600'), ensuring robust, reliable returns whether you’re exploring shallow structure or probing deeper drop-offs.
• Mid-band 95–155 kHz operation plus a broad bandwidth (60 kHz total) that supports CHIRP-ready performance while offering precise target separation.
• Beamwidth 26° to 17° concentrates energy on targets for improved discrimination, ideal for identifying fish clearly near structures or suspended in the water column.
• Low-profile thru-hull bronze housing designed for speed and stability, delivering solid resolution when installed correctly on stepped, planing or displacement hulls.
• Versatile mounting options while primarily designed as a thru-hull unit, with a transom-mount variant (TM150M) available in the same family for boats that prefer stern mounting.
• All-weather, salt- and freshwater capable—built to handle the rigors of coastal and inland fishing environments without compromising signal quality.

Ideal use cases and practical applications

Whether you’re chasing crappie along weed edges, targeting bass near submerged structures, or exploring inshore channels for striped bass, the B150M gives you reliable depth readings and crisp target returns at speeds that keep up with your approach. The 12° tilt is particularly advantageous when you’re running routinely in waters with noticeable hull deadrise, helping the beam stay focused downward rather than losing energy to hull geometry.

For boats with stepped, planing, or displacement hulls, the bronze thru-hull design minimizes drag while preserving signal quality, making this transducer a solid choice for performance-oriented anglers who value speed and accuracy in equal measure. And if you ever need to explore alternative mounting, the TM150M transom-mount option in the same family provides a compatible CHIRP-ready solution.
