Detailed description

Designed for inshore and offshore fishing, the through-hull Garmin AIRMAR B175HW with 0° tilt is a 1 kW CHIRP transducer. It provides fast-response depth and water temperature detection, optimized for fiberglass and wooden hulls.

Wide-beam CHIRP performance

The B175HW operates across a high-frequency range of 150 to 250 kHz, delivering a total bandwidth of 100 kHz. Its fixed 25° wide beam provides extended coverage, doubling fish detection in the upper water column compared to traditional narrow-beam transducers. This feature is suited for detailed resolution and improved target separation up to a maximum depth of 152 meters (500 feet) in ideal conditions.

Design and installation

This transducer uses a through-hull design with a low-profile, tilted element. Its bronze housing is flush with the hull, protruding less than 6 mm (1/4 inch), allowing use on trailerable boats without risk of damage. The 0° tilted element is designed for hull angles from 0° to 7°, eliminating the need for a fairing block for optimal horizontal alignment of the ceramic element. It features an 8-pin Garmin connector and includes Xducer ID® technology for simplified configuration. Installation requires a 95 mm (3-3/4 inch) hole. A 11.8-meter (39-foot) cable is provided for connection.

Expert opinion

« Technical analysis: Garmin AIRMAR B175HW 0° CHIRP wide beam transducer »

The Garmin AIRMAR B175HW transducer is a technically sound solution for demanding navigators and anglers. Its defining feature is its 0° tilted element, making it specifically suitable for hulls with deadrise angles between 0° and 7°. This design eliminates the need for a compensating shoe, simplifying installation and reducing hull drag. The bronze body ensures excellent corrosion resistance in marine environments, extending equipment lifespan.

The key advantage of this model is its CHIRP technology with a wide beam (25° constant across the 150–250 kHz range). This beam width provides twice the water column coverage compared to high-frequency narrow-beam transducers. For fishing applications, this translates to improved detection of fish schools and better visualization of underwater structures, particularly effective for coastal and pelagic fishing where resolution and coverage are critical. Integration with Garmin systems is streamlined via the 8-pin connector and Xducer ID® technology, which automatically optimizes sounder settings, minimizing post-installation manual adjustments.

This transducer is ideal for medium to large fiberglass or wooden vessels requiring robust detection performance without compromising hydrodynamics. It is less suitable for hulls with deadrise angles exceeding 7°, where a version with a different tilt angle would be required for optimal performance.

Frequently Asked Questions

Need help? Contact us

What does the designation "HW" mean for this depth sounder?

The HW designation stands for High-Wide. This indicates that the transducer uses CHIRP technology over a high-frequency range (150–250 kHz) with a wide beam. This feature is ideal for detecting fish in the upper water column and for extended coverage beneath the boat.

What is the operating frequency range of the B175HW transducer?

The AIRMAR B175HW transducer operates on a high-frequency CHIRP range, specifically from 150 to 250 kHz. This wide bandwidth provides excellent target separation and high image clarity.

What is the output power of this depth sounder?

The Garmin AIRMAR B175HW transducer is a 1 kW (1000 Watts) unit. This high power ensures good deep-water performance and reliable target detection, even in challenging conditions.

What data does the AIRMAR B175HW transducer measure?

The AIRMAR B175HW transducer provides essential data for navigation and fishing. It can measure and transmit water depth and water temperature.

What is the main advantage of CHIRP High-Wide (HW) technology?

The main advantage of CHIRP High-Wide technology is its ability to provide a constant and wide 25° beam angle across its entire frequency range. This allows for:

Greater coverage beneath the boat, increasing the chances of detecting fish.Better detection of fish in the upper water column.Superior target separation, enabling individual fish to be distinguished from schools or structures.

What is the beam angle of this depth sounder?

The AIRMAR B175HW transducer features a constant 25° beam angle across its entire frequency range (150–250 kHz). This wide angle is designed to maximize coverage beneath the boat and simplify fish detection.

Is the B175HW transducer compatible with devices from brands other than Garmin?

No, the Garmin AIRMAR B175HW transducer is specifically designed with a Garmin 12-pin connector and is optimized to work with Garmin CHIRP-compatible fishfinder systems. It is not directly compatible with devices from other brands without non-standard adapters or modifications.

Can this transducer be used with an external Garmin fishfinder module?

Yes, the B175HW sounder can be used with a compatible Garmin external CHIRP 1 kW fishfinder module, such as the GSD™ 25 module. This allows adding advanced fishfinder capabilities to existing Garmin navigation systems.

For which deadrise angle of the hull is the B175HW transducer designed with a 0° tilt?

The B175HW transducer with 0° tilt is specifically designed for hulls with a deadrise angle between 0° and 7°. A 0° tilt means the transducer is designed to be flush-mounted on the hull, compensating for small deadrise angles so the beam is directed vertically downward.

Does installing this depth sounder require drilling through the hull?

Yes, as it is a through-hull transducer, installing the Garmin AIRMAR B175HW requires drilling a hole in your boat’s hull. This hole allows the transducer body and its cable to pass through the hull, ensuring optimal exposure of the transducer element to the water.

Which hull materials are compatible with the installation of this depth sounder?

The Garmin AIRMAR B175HW transducer is optimized and recommended for installation on fiberglass and wood hulls. These materials allow efficient transmission of acoustic signals.

Is the B175HW transducer suitable for aluminum hulls?

The B175HW transducer is not directly suitable for aluminum hulls. Bronze transducers, such as the B175HW, can cause galvanic corrosion if installed directly on an aluminum hull. For installation on aluminum, specific stainless steel or plastic transducers with appropriate isolation kits would be required, or mounting via a pocket or shoe.

How to ensure correct installation to avoid air bubbles?

To ensure correct installation and avoid air bubbles that could disrupt the depth sounder’s performance:

Select a mounting location where the water flow is smooth and free of turbulence.Clean the hull surface thoroughly before installation.Apply high-quality marine sealant around the depth sounder body and hull hole, following the manufacturer’s instructions.Tighten the mounting nuts gradually and evenly to ensure a perfect seal and prevent air from being trapped.

Is antifouling necessary on the depth sounder?

Yes, it is recommended to apply antifouling to the submerged part of the transducer to prevent the buildup of marine organisms, which could affect its performance. However, it is crucial to use a water-based antifouling. Copper- or solvent-based antifoulings can damage the transducer or reduce its effectiveness.

What is included in the Garmin AIRMAR B175HW transducer package?

The Garmin AIRMAR B175HW transducer package typically includes the following items:

The AIRMAR B175HW transducer with integrated cable.The mounting and installation kit (including nuts, washers, and gaskets).The product documentation (installation and user manual).

What is the manufacturer's warranty duration for this Garmin AIRMAR transducer?

In accordance with European legislation, the Garmin AIRMAR B175HW transducer is covered by a legal conformity warranty of two (2) years from the date of purchase. This warranty covers manufacturing and material defects under normal conditions of use.
