Airmar SS175C Navico 9-Pin Review – Best & Worst Guide

Introduction

The Airmar SS175C Navico 9-Pin is a premium thru-hull CHIRP transducer engineered for Navico systems including Simrad, Lowrance, and B&G. Designed with a 12° tilted element, this stainless-steel marvel targets vessels with moderate hull deadrise, offering precise sonar alignment. Operating in the low CHIRP frequency range (40–60 kHz), it’s ideal for deep-sea fishing and superior target separation.

Whether you’re a commercial angler or a recreational deep-water explorer, the Airmar SS175C Navico 9-Pin brings industry-grade sonar clarity right to your Navico chartplotter. Built for endurance and precision, it delivers high-resolution bottom imagery even at cruising speeds. If you’re serious about understanding what lies beneath, this transducer is your ultimate ally.

Overview / What Is Airmar SS175C Navico 9-Pin

The Airmar SS175C Navico 9-Pin is part of Airmar’s elite CHIRP product line, offering 1kW of output power and exceptional sonar clarity. With a low-frequency CHIRP range of 40–60 kHz, it’s optimized for detecting large gamefish, bait schools, and bottom structures at depths over 3000 feet.

This transducer includes a temperature sensor, supports thru-hull mounting, and is encased in corrosion-resistant stainless steel for saltwater durability. It’s directly compatible with Navico 9-pin systems, eliminating the need for adapters in most cases. Installation is simplified thanks to the 12° tilt, which compensates for moderate hull angles, providing vertical sonar returns for accurate readings.

Benefits of Low CHIRP for Offshore Anglers

Low CHIRP frequencies penetrate deeper than high-frequency transducers, making them ideal for deep-sea applications. The Airmar SS175C Navico 9-Pin enables long-range fish detection and performs especially well in murky or thermocline-heavy waters.

This technology is vital for offshore anglers targeting tuna, swordfish, or deep-dwelling snapper. CHIRP pulses continuously across a frequency range, producing crisp arches and better target definition even when fish are close to the bottom. Paired with Navico’s StructureScan™ or Broadband Sonar™, the experience is immersive and data-rich.

How to Install Airmar SS175C Navico 9-Pin

To install the Airmar SS175C Navico 9-Pin, first determine the optimal hull location — typically forward of the prop wash and in constant water contact. Drill a properly sized hole using the included template, insert the transducer with sealant, and torque the locking nut per Airmar’s specs.

Route the 9-pin cable directly to your Simrad, Lowrance, or B&G display. Use cable clamps to avoid stress points and sharp bends. After installation, calibrate via your Navico system for accurate temperature, depth, and CHIRP frequency settings. Firmware updates may enhance compatibility, so check the manufacturer’s latest recommendations.

Maintenance Tips

To ensure lasting performance from your Airmar SS175C Navico 9-Pin, follow these key maintenance practices:

• Clean regularly: Use a non-abrasive cloth and mild soap to clean marine growth from the transducer face.
• Inspect wiring: Check for wear, corrosion, and UV damage on the cable jacket and connector.
• Avoid painting over the face: If applying antifouling paint, use only transducer-safe coatings around the housing.
• Use dielectric grease: Apply at the 9-pin connector for added corrosion resistance.

With minimal effort, your transducer will deliver consistent sonar performance and accurate water temperature readings for years to come.

CHIRP Sonar Troubleshooting with Navico 9-Pin

Even the best systems can experience hiccups. If your Airmar SS175C Navico 9-Pin isn’t delivering expected results, start by checking the following:

• Connector seating: Ensure the 9-pin plug is fully inserted and locked into the Navico port.
• Signal loss: Intermittent readings may suggest pin damage or poor waterproofing. Inspect the connector closely.
• Transducer placement: Turbulence or cavitation near the transducer face can distort signals—consider repositioning if needed.

Still not resolved? Try connecting a compatible transducer to isolate whether it’s a display or cable issue. Also, recheck CHIRP settings in your sonar menu and match the frequency band with the installed transducer model.

Cost and Durability: Is It Worth It?

The Airmar SS175C Navico 9-Pin may come at a premium price point, but its performance and durability make it a smart investment. Made from marine-grade stainless steel, this transducer resists corrosion, water intrusion, and thermal stress.

Given its ability to track bottom beyond 3000 ft and deliver sharp target separation at trolling speeds, it easily justifies its value over time. It’s designed for high-end installations where performance cannot be compromised. Compared to plastic-bodied units, its operational life is significantly longer and more stable in rough marine environments.

Expert Advice and Pro Recommendations

If you operate a high-performance fishing vessel, you cannot go wrong with the Airmar SS175C Navico 9-Pin. Its low CHIRP frequency, durable housing, and seamless Navico integration are ideal for offshore trolling and deep-bottom fishing. Many tournament anglers choose this setup for its pinpoint accuracy and long-range depth capabilities.

Detailed FAQ Section

What is the depth capability of Airmar SS175C Navico 9-Pin?

The Airmar SS175C Navico 9-Pin transducer is capable of reaching depths of over 3000 feet, thanks to its low CHIRP frequency range. This makes it a favorite among offshore fishermen targeting deep-dwelling species like tuna, grouper, and halibut. Its 1kW output ensures strong sonar signals that hold even when cruising at speed. Bottom definition, bait returns, and large fish arches are clearly visible on compatible Navico displays.

Is the Airmar SS175C Navico 9-Pin compatible with Lowrance?

Yes, the Airmar SS175C Navico 9-Pin is fully compatible with most Lowrance systems that support CHIRP sonar and have a 9-pin connector. Models such as the Lowrance HDS PRO and Elite FS support this transducer without the need for adapters. Always check for the latest software updates and confirm CHIRP settings are configured correctly to optimize image clarity and target tracking.

What boat types are best suited for this transducer?

This model is best suited for fiberglass and metal hull boats with a deadrise between 8° and 15°. The 12° tilt ensures the sonar beam is directed straight down, even when mounted on a V-hull. It is commonly used in offshore sportfishing boats, center consoles, and cruisers. Trailer boats can also benefit from this transducer, but installers must ensure the housing is not exposed to trailer bunks or lifting strakes.

Can I use the SS175C on a Yamaha-powered vessel?

Absolutely. The Yamaha Outboards community often relies on Airmar CHIRP technology for fishing accuracy and depth finding. Whether paired with Simrad or Lowrance, the SS175C complements Yamaha-powered setups with reliable sonar data, enhancing trolling patterns and fishing efficiency. It is highly recommended by boat rigging experts who outfit Yamaha-driven boats for offshore fishing tournaments.

What’s the difference between the 12° and 20° models?

The 12° version of the Airmar SS175C is ideal for hulls with an 8°–15° deadrise, whereas the 20° model is intended for steeper hull angles. Choosing the correct tilt ensures the sonar beam is perpendicular to the seafloor, which improves image accuracy and depth tracking. If unsure, measure your deadrise angle and consult with a marine electronics installer before purchasing.

Conclusion

With its high-precision sonar, reliable build, and compatibility with Navico’s top-tier systems, the Airmar SS175C Navico 9-Pin is a top-tier transducer. Designed for serious boaters and anglers, it offers reliable bottom tracking, excellent durability, and integration with Simrad, Lowrance, and B&G electronics.

From long-range fishing to detailed structure scanning, this unit does it all — and with proper maintenance, it’ll keep doing it season after season.
