Overview
300 W Airmar’s B150M delivers a great combination of shallow and mid-depth performance.
Operating at a frequency range of 95 to 155 kHz, this transducer reveals fish in shallow waters and deeper depths down to 183 m (600′) with ultra-clear target resolution.
Narrow beam angles are perfect for detecting fish holding close to structures and suspended fish—ideal for freshwater, inshore, or coastal fishing in shallow to medium depth. Tilted Element ™ transducers have the ceramic element fixed at a 20°, 12°, or 0° angle within the housing.
When the transducer is installed almost flush to the hull, the tilt of the element corrects for the hull deadrise, orienting the beam directly down. This ensures maximum echo returns to the transducer for more accurate depth readings.
Available in three Tilted Element models: Fixed 20° tilted version for 16 to 24° hull deadrise angles Fixed 12° tilted version for 8 to 15° hull deadrise angles Fixed 0° tilted version for 0 to 7° hull deadrise angles

FAQs
How do I check if my hull is compatible with this transducer’s tilt?
Measure your hull’s deadrise angle at the installation point and ensure it matches the tilt angle printed on the transducer.
How is the tilted element aligned during installation?
When installed almost flush to the hull, the tilt of the element corrects for the hull deadrise, orienting the beam directly down.
Where is the tilt angle marked on the B150M transducer for identification?
The tilt angle is stamped on the top of the transducer for easy identification during installation.
Is the B150M suitable for use with wooden hulls?
Yes, the B150M can be installed on fiberglass or wood hulls, as stated in the specifications.
Is the B150M suitable for retractable mounting?
No, the B150M is not a retractable housing transducer.
How do I ensure the correct tilt model for my hull’s deadrise?
Match the tilt angle (0°, 12°, or 20°) of your B150M to your hull’s deadrise at the intended mounting location.
What power is required to operate the B150M 20 F2 transducer?
The B150M 20 F2 has a power rating of 300 W.
