This model is a member of the revered Airmar SS175C family, trusted across the industry for its solid stainless steel housing, dual ceramic elements, and long-lasting durability in saltwater and freshwater conditions. Whether you’re upgrading an existing system or setting up a new vessel for offshore exploration, the Airmar SS175C Garmin 8-Pin offers a perfect blend of technology, design, and resilience.

Overview / What Is Airmar SS175C Garmin 8-Pin

The Airmar SS175C Garmin 8-Pin is a high-performance, thru-hull CHIRP transducer featuring a 20-degree tilted ceramic designed for high-speed vessels and boats with deadrise hulls. The High Wide (HW) CHIRP capabilities cover a frequency range of 150–250 kHz, delivering ultra-clear target resolution across the water column. It’s ideal for identifying fish targets, bottom structures, and bait schools in diverse marine environments.

This model is engineered for seamless integration with Garmin’s sonar systems, particularly those with 8-pin connections. The stainless steel construction offers superior protection against corrosion, while the internal tilt eliminates the need for a fairing block, making installation simpler and more accurate.

Key Benefits of Airmar SS175C Garmin 8-Pin

• High Wide CHIRP: Exceptional resolution with greater coverage under the boat.
• 20° Tilted Element: Ideal for hulls with deadrise angles, ensuring optimal beam alignment.
• Stainless Steel Housing: Corrosion-resistant and perfect for saltwater use.
• Garmin 8-Pin Compatibility: Easy integration with Garmin CHIRP-enabled sonar devices.

With a frequency range tailored to high-speed scanning and shallow to mid-depth applications (up to 600 ft), this transducer delivers unmatched target separation and detail clarity.

How to Install Airmar SS175C Garmin 8-Pin

Installing the Airmar SS175C Garmin 8-Pin requires precision and care, as it is a thru-hull model. Begin by identifying the correct hull position — ideally near the keel where water flow is clean and undisturbed. Since the transducer has a 20° tilted element, it compensates for hull deadrise, ensuring a vertical sonar beam even on angled surfaces.

Once the hole is drilled and deburred, apply marine-grade sealant around the flange before inserting the transducer. Tighten all mounting hardware securely, connect the 8-pin cable to your Garmin unit, and run a sonar test to verify performance. It’s recommended to consult a professional if unsure, as improper installation can lead to data inaccuracies or water intrusion.

Performance Testing and Real-World Use

In field conditions, the Airmar SS175C Garmin 8-Pin excels in providing crisp images with accurate bottom returns, even at speeds exceeding 25 knots. Fish arches and bait balls are distinguishable with minimal noise, making it a top choice among deep-sea fishermen and coastal cruisers alike.

Compared to standard broadband sonar or dual-frequency transducers, CHIRP delivers significantly better target separation and coverage. Combined with Garmin’s echo sounders, users benefit from faster refresh rates, deeper scanning, and better fish tracking in high-traffic or turbulent zones.

Maintenance Tips

Maintaining your Airmar SS175C Garmin 8-Pin transducer is critical for long-term accuracy and reliability. Regularly inspect the stainless steel housing for marine growth, corrosion, or damage. Monthly cleaning with a soft brush and mild soap helps prevent buildup, especially in saltwater environments.

Check the cable for wear or cracking, especially at junction points. Ensure the sealant remains intact around the thru-hull to prevent water leaks. During winter layups, consider removing the transducer or covering it securely to prevent damage from ice or debris.

Expert Advice and Pro Recommendations

Marine professionals recommend the Airmar SS175C Garmin 8-Pin for those seeking CHIRP clarity with wider beam coverage. Its 20° tilt is particularly useful for V-hull boats, ensuring consistent performance at various speeds and angles. Pair it with Garmin’s GSD 26 or GPSMAP series for best results.

Understanding CHIRP Technology

CHIRP (Compressed High-Intensity Radiated Pulse) sonar sends continuous frequency sweeps, unlike traditional sonar that uses single frequencies. This enables better target separation, deeper penetration, and clearer readings.

With the Airmar SS175C’s High Wide frequency range (150–250 kHz), you can identify fish stacked tightly or close to the bottom. This advantage becomes especially evident in rough waters or when scanning structures such as reefs, wrecks, and ledges.

Airmar SS175C Garmin 8-Pin Troubleshooting Tips

If your sonar images appear distorted or signal drops occur, inspect for air bubbles around the transducer, faulty wiring, or incompatible settings. Ensure the firmware of your Garmin sonar device is updated.

For unusual noise or interference, check for nearby electronics causing signal cross-talk. If necessary, re-route the cable away from power lines or install a noise filter. Always verify your tilt alignment is still correct after hull impacts or servicing.

Detailed FAQ Section

What is the maximum depth capability of the Airmar SS175C Garmin 8-Pin?

The maximum depth capability depends on water conditions and sonar settings but generally reaches up to 600 feet (183 meters) in optimal conditions. In clear saltwater, users can expect consistent bottom tracking up to that depth, thanks to the High Wide CHIRP frequency band. However, the actual reading may vary depending on vessel speed, water clarity, and seabed composition. For best results, pair it with a compatible Garmin CHIRP sounder like the GSD 26 and maintain a clean transducer surface.

Can I install the Airmar SS175C Garmin 8-Pin myself?

Yes, but it’s only recommended if you have experience with thru-hull installations. This unit requires hull drilling and proper sealing, which, if done improperly, can lead to water ingress or inaccurate sonar readings. Always follow the included instructions or consult a certified installer. For those unfamiliar with deadrise compensation and marine-grade sealants, professional help ensures longevity and optimal positioning. This model’s built-in 20° tilt simplifies beam alignment, reducing the need for external fairing blocks.

What makes the SS175C series different from other Airmar models?

The SS175C series is known for its CHIRP capabilities and tilt-element technology. Unlike traditional single-frequency units, this series uses wideband CHIRP to deliver detailed images across a broader range. The stainless steel construction adds durability, while its fixed tilt ensures sonar beams are vertical to the seafloor, even on angled hulls. Compared to plastic or bronze models, the SS175C stands out for its high-speed performance, reliability, and precision in both saltwater and freshwater environments.

Is it compatible with other marine electronics besides Garmin?

This specific version of the SS175C comes with a Garmin 8-pin connector, making it compatible exclusively with Garmin sonar units that support CHIRP. However, Airmar manufactures the SS175C in other connector types for brands like Raymarine, Lowrance, and Simrad. If you use a different MFD (multi-function display), be sure to purchase the right connector version or an adapter. Always confirm device compatibility via the Airmar transducer cross-reference chart or consult your marine electronics supplier.

How does it perform in rough water and high speeds?

The Airmar SS175C Garmin 8-Pin is designed for high-performance boating. Its thru-hull mount and 20° internal tilt allow it to maintain consistent bottom tracking in rough water. At speeds up to 30+ knots, the sonar image remains stable, making it ideal for fast fishing boats or patrol vessels. The stainless steel housing resists vibration, while the High Wide frequency band provides wide coverage under the hull. For best high-speed performance, proper installation and cable routing are essential. Be sure to mount the transducer in a low-turbulence area of the hull.

Conclusion

The Airmar SS175C Garmin 8-Pin is a powerhouse CHIRP transducer engineered for high-precision, high-speed marine use. From its stainless steel body to the High Wide sonar clarity, this product delivers professional-grade performance for both recreational and commercial users. Whether you’re hunting deep-sea giants or mapping underwater terrain, this transducer’s wide beam and robust durability offer unmatched advantages.
