Garmin AIRMAR B175L 0° Tilt

Garmin AIRMAR B175L 0° Tilt

Garmin AIRMAR B175L 0° Tilt are designed for serious offshore anglers and deep-water explorers, this 1kW CHIRP transducer delivers the ultimate in depth penetration and target clarity without the need for a bulky fairing block.

As part of the renowned Airmar Tilted Element™ series, the B175L is the perfect solution for smaller vessels such as centre consoles or any boat where a low-profile installation is essential. By mounting almost flush to your hull, it minimises drag and allows your boat to sit safely on trailer rollers or bunks without the risk of damaging the transducer.

This 0° Tilt version is specifically engineered for hulls with a deadrise angle of 0° to 7°. The internal ceramic element is fixed at a 0° angle, ensuring the sonar beam is aimed directly at the seabed for the most accurate depth readings and strongest echo returns possible.

Operating on the Low-frequency CHIRP band (40-60 kHz), the B175L is a true "deep-water performer." It is designed to punch through the water column to reach depths of up to 762m (2,500ft), making it an essential tool for tracking bottom structure and identifying large targets in the deep blue.

The B175L offers a high-performance 1kW output in a compact bronze housing, providing exceptional resolution even at higher cruising speeds. It is an excellent choice for fibreglass and wood hulls, offering the reliability and precision that Garmin and Airmar are world-famous for.

Garmin AIRMAR B175L 0° Tilt FAQs

What makes the B175L different from other transducers in the range?

The ‘L’ stands for Low Frequency. While many standard transducers struggle as the water gets deeper, the B175L operates between 40-60 kHz. This low-frequency CHIRP band is designed specifically for deep-water performance, allowing you to track the bottom and see targets at depths of up to 2,500 feet (approx. 760 metres). It’s the "deep sea specialist" of the B175 family.

Why do I need the 0° Tilt version?

This is a "Tilted Element" transducer, meaning the ceramic heart of the unit is fixed at a specific angle inside the housing. The 0° Tilt model is designed for boats with a hull deadrise (the angle of the V-shape at the bottom of your boat) between 0° and 7°.

The Goal: Even though the housing sits flush with your hull, the internal element ensures the sonar beam points straight down to the seabed for the most accurate readings.

Note: If your hull has a steeper angle, you may require the 12° or 20° version instead.

Will it fit my boat's hull material?

The B175L features a bronze housing. This makes it an excellent choice for fibreglass or wood hulls.

Important: You must never install a bronze transducer in an aluminium hull, as this will cause electrolytic corrosion which can damage your boat. For aluminium hulls, please ask us about the stainless steel (SS175) equivalents.

Do I need a fairing block?

No, and that’s one of the best things about the B175 series. Because it is a low-profile, flush-mount design, it protrudes less than 6mm (1/4 inch) outside the hull. This creates far less drag than a traditional fairing block and means the boat can sit safely on trailer rollers or bunks without damaging the transducer.

What kind of beamwidth should I expect?

The B175L provides a beamwidth of 32° to 21°. This wide coverage is fantastic for "searching" a large area of the water column in deep offshore environments, making it much easier to spot schools of fish or significant bottom structures.

Is it compatible with my Garmin chartplotter?

This is an 8-pin transducer. It connects directly to Garmin’s "xsv" series (like the GPSMAP 1223xsv) or GSD sonar modules. If you have a newer 12-pin Garmin unit, don't worry—we can provide an adapter cable (8-pin to 12-pin) to get you up and running.

Can I use this alongside another B175 transducer?

Yes, many of our customers choose to pair this with a B175H (High Frequency) or B175M (Medium Frequency) for a dual-band setup. Using a Garmin "Y-cable," you can run both simultaneously, giving you the deep-water reach of the 'L' and the high-definition target separation of the 'H' at the same time.

Are there any specific installation tips?

• • Alignment: There is an arrow on top of the transducer; this must point towards the keel (the centreline) of your boat to ensure the tilt is aligned correctly.
  • Cooling: As a high-power 1kW CHIRP transducer, it is vital that it is only operated in the water. Running it "dry" on the trailer for extended periods can cause it to overheat and fail.
  • Paint: If you anti-foul your hull, ensure you use a water-based anti-fouling paint specifically for transducers on the face of the unit.
