Garmin B175L Bronze Top & Worst Features
Introduction
The Garmin 010-11938-20 40-60KHZ 0D Tilt Bronze B175L TH 8P is an advanced thru-hull CHIRP transducer designed for anglers and marine enthusiasts who require exceptional deep-water sonar performance. Operating at low frequencies (40–60 kHz), it delivers superior depth penetration while maintaining excellent target definition. The 0° tilt design ensures perfect sonar beam alignment on flat hulls, making it suitable for various vessel types. Built with a robust bronze housing, it withstands harsh marine environments, providing reliable service for years. Its 8-pin connector ensures seamless compatibility with modern Garmin devices, offering an easy upgrade path for existing setups.
Overview / What Is Garmin B175L Bronze
The Garmin B175L Bronze is a low-frequency CHIRP transducer engineered for offshore fishing and deep-water exploration. Unlike high-frequency models, this unit excels at detecting targets at greater depths, making it perfect for species like swordfish, tuna, and other deep-dwelling fish. Its 40–60 kHz frequency range provides a wide coverage area with strong bottom detection capabilities.
With its durable bronze construction, the B175L is optimized for use on fiberglass and wooden hulls, offering long-term resistance against corrosion and marine wear. This model’s low-frequency CHIRP sweeps continuously across the frequency band, giving boaters crisp, detailed sonar returns and superior target separation.
Unique Features of Garmin B175L Bronze
What sets the Garmin B175L Bronze apart from other transducers is its deep-water capability. While other devices may lose clarity or signal at extreme depths, the B175L continues to deliver accurate readings. Its low-frequency sonar penetrates deeper than high-frequency alternatives, giving anglers an edge when targeting deepwater species.
- Low-frequency CHIRP (40–60 kHz) for extreme depth penetration
- 0° tilt ideal for flat hull installations
- Robust bronze housing for saltwater durability
- Wide beam coverage for improved fish detection
Technical Specifications and Performance Insights
The Garmin B175L Bronze’s specifications are tailored for professional-grade performance:
- Frequency Range: 40–60 kHz
- Beamwidth: 16–25°
- Depth Capability: Up to 3000 ft
- Housing Material: Bronze
- Connector: 8-pin
This combination ensures accurate target detection, even at depths exceeding 3000 feet, making it one of the best options for offshore vessels.
How to Install Garmin B175L Bronze
Installing the Garmin B175L Bronze requires careful positioning and sealing to ensure optimal performance and hull integrity. The installation process involves:
- Selecting a location on the hull where water flow is smooth and free of bubbles.
- Drilling an appropriately sized hole and applying marine-grade sealant.
- Securing the transducer’s bronze housing and tightening it correctly.
- Routing the 8-pin cable to your Garmin chartplotter or fishfinder.
Because thru-hull installation involves structural modifications, professional installation is strongly recommended.
Maintenance Tips
Proper maintenance extends the life and performance of the Garmin B175L Bronze. Here’s how to keep it in top shape:
- Rinse with freshwater after every saltwater use.
- Inspect bronze housing for corrosion or pitting periodically.
- Clean the transducer face to remove algae or barnacles.
- Apply antifouling paint to prevent marine growth.
Consistent care will ensure accurate sonar readings and prevent damage caused by marine buildup.
Expert Advice and Pro Recommendations
Experts recommend pairing the Garmin B175L Bronze with Garmin’s high-end chartplotters for maximum performance. Low-frequency CHIRP transducers like the B175L are indispensable for anglers targeting fish at depths beyond 1500 feet. Additionally, using a proper fairing block (if required) can further optimize sonar signal quality.

Advanced Sonar Benefits for Offshore Fishing
The Garmin B175L Bronze is engineered specifically for deepwater anglers. Low-frequency CHIRP technology penetrates greater depths, providing detailed sonar images of fish, bait, and structures that other devices miss. It is ideal for offshore fishing where depth accuracy and strong target returns are essential.
Its beamwidth ensures wide coverage, making it easier to locate fish schools, even in challenging environments. This capability makes it a favorite among professional charter captains and serious sportfishing enthusiasts.
Detailed FAQ Section
1. How do I properly install the Garmin B175L Bronze?
Proper installation is key to maximizing performance. Choose a flat section of the hull with consistent water flow. Drill the mounting hole, apply marine-grade sealant, and insert the transducer. Tighten the bronze housing to prevent leaks. Finally, connect the 8-pin cable to your Garmin device. Professional installation is highly recommended to avoid structural damage and ensure correct alignment.
2. Why is low-frequency CHIRP better for deep water?
Low-frequency CHIRP sonar penetrates water more effectively than high frequencies, reaching depths over 3000 feet. This makes it ideal for targeting deepwater fish like tuna and swordfish. Although resolution in shallow waters may be slightly lower than high-frequency models, the B175L excels where depth is a priority.
3. Is the Garmin B175L Bronze compatible with all Garmin devices?
This transducer is designed with an 8-pin connector, making it compatible with most modern Garmin fishfinders and chartplotters. Older models may require an adapter. Check Garmin’s compatibility guide before purchase to ensure seamless integration with your existing electronics.
4. How can I prevent marine growth on the transducer face?
Apply a thin coat of antifouling paint specifically designed for transducers. Avoid using metallic paints that could react with the bronze housing. Regular cleaning and inspections will prevent barnacle buildup and ensure the sonar beam remains unobstructed for accurate readings.
5. What is the expected lifespan of the Garmin B175L Bronze?
With proper maintenance, including cleaning, anti-fouling treatment, and inspection of seals, the Garmin B175L Bronze can last many years. Its bronze construction is inherently corrosion-resistant, making it a reliable choice for long-term offshore use.
Conclusion
The Garmin 010-11938-20 40-60KHZ 0D Tilt Bronze B175L TH 8P is a premium choice for serious offshore anglers who demand unmatched deepwater sonar performance. Its low-frequency CHIRP technology, durable bronze construction, and easy integration with Garmin devices make it a top contender in marine electronics.
