Garmin B175M Bronze 20° Tilt Thru-Hull Transducer (1kW)

High-Performance CHIRP Sonar for Deep Water & Detail

The Garmin B175M (010-11939-22) is a powerhouse 1kW thru-hull transducer designed for offshore anglers who need a balance between deep-water penetration and high-target resolution. This Medium-Band CHIRP transducer operates across a frequency range of 85-135 kHz, making it exceptionally effective at identifying fish targets at mid-depths and showing clear bottom structure.

This specific model features a 20° tilted element, which is engineered for boats with a hull deadrise of 16° to 24°. The tilt ensures the sonar beam points straight down without the need for a bulky fairing block, reducing drag and improving high-speed performance.

Medium CHIRP Performance for Versatile Fishing

The medium-band CHIRP frequency offers excellent all-around sonar performance, making it ideal for:

• Offshore and nearshore fishing

• Targeting baitfish and gamefish

• Strong bottom definition in shallow to mid-depth water

• Improved fish separation compared to traditional single-frequency transducers

⚡ Powerful 1kW Output

With a 1,000-watt power rating, the B175M delivers:

• Deep-water performance

• Clear target resolution at speed

• Strong returns even in challenging conditions

This makes it a preferred choice for anglers running larger Garmin chartplotters and fishfinders.

20° Tilted Element for Accurate Sonar Returns

The 20-degree tilted element is optimized for hull deadrise angles, allowing the transducer to:

• Aim the sonar beam straight down

• Eliminate the need for fairing blocks

• Improve bottom tracking and clarity

Durable Bronze Thru-Hull Construction

The bronze housing provides:

• Maximum strength and corrosion resistance

• Excellent acoustic performance

• Long service life in saltwater environments

Recommended for fiberglass hull installations (not suitable for aluminum or steel hulls).

Garmin 8-Pin Compatibility

The 8-pin connector ensures seamless integration with compatible Garmin sonar and chartplotter systems, delivering plug-and-play installation and reliable signal transmission.

Key Features & Benefits

• 1kW Power Rating: Provides the energy needed to "punch" through the water column, reaching depths up to 1,500 feet (depending on water conditions).

• Medium-Band CHIRP (85-135 kHz): Offers a wider range of frequencies than traditional sonar, resulting in superior target separation and crisp imagery of baitfish and predators.

• Tilted Element Design: The ceramic element is fixed at a 20° angle inside the housing. This compensates for your hull's deadrise, ensuring the sonar beam is perfectly vertical for accurate depth and positioning.

• Bronze Housing: Built for durability in saltwater environments; ideal for heavy fiberglass or wood hulls.

• Low-Profile Installation: Sits nearly flush with the hull, minimizing turbulence and allowing for clean water flow to the propeller.

Technical Specifications

Why Choose the B175M?

The "M" (Medium) frequency band is often considered the "sweet spot" for coastal and offshore fishing. It provides better depth capability than High-Band transducers while maintaining much sharper detail than Low-Band transducers. If you are hunting for tuna, grouper, or snapper in 200 to 1,000 feet of water, the B175M is an industry-standard choice.

Installation Note: This is an 8-pin transducer. If you are connecting this to a newer Garmin XSV or GSD series unit that uses a 12-pin port, you may require an adapter cable (Garmin 010-12718-57).
