If you’re seeking unparalleled sonar clarity, durability, and compatibility with leading marine systems, this model is worth your serious attention.
Whether you’re navigating deep seas, charting unknown terrain, or targeting elusive fish species, the Airmar SS175C-20-HW CHIRP is engineered to give you real-time, high-resolution sonar feedback in the most demanding marine environments.
Overview / What Is Airmar SS175C-20-HW CHIRP
The Airmar SS175C-20-HW CHIRP is a high-performance, stainless steel thru-hull transducer. Built to transmit over a range of frequencies (150–250 kHz), it delivers high-definition bottom and structure imaging. With a 20-degree tilted element, it’s ideal for hulls with deeper deadrise angles, providing perpendicular sonar returns for enhanced accuracy.
Designed with a Mix-and-Match plug, it offers flexible connectivity to various CHIRP-compatible sonar systems. Its high-wide (HW) beamwidth allows it to scan a broader section of the water column, delivering superior target separation and fish detection, even in shallow depths.
Why High Wide CHIRP Transducers Matter
High Wide (HW) CHIRP transducers such as the Airmar SS175C-20-HW CHIRP transmit across a wider beamwidth, typically 25°. This increases coverage below your boat and improves the chances of detecting fish near the bottom or in spread-out schools. The CHIRP function means it sends out continuous frequencies instead of a single pulse, resulting in better resolution and clarity.
This makes it ideal for both offshore and inshore anglers who need precise sonar detail and want to avoid interference that can plague traditional sonar signals.
Installation Guidelines: How to Install Airmar SS175C-20-HW CHIRP
Proper installation is crucial for getting optimal performance from the Airmar SS175C-20-HW CHIRP. Being a thru-hull model, the transducer must be installed through a carefully drilled hole in the hull below the waterline. Tilt angle should match the hull’s deadrise.
Steps include:
- Choose a suitable location below the waterline with no turbulence.
- Drill the hull using proper safety and sealing techniques.
- Mount the stainless steel body securely using marine-grade sealant.
- Connect the Mix-N-Match plug to your compatible sonar system.
Note: Incorrect installation can compromise sonar readings and lead to water intrusion.
Top Benefits of Airmar SS175C-20-HW CHIRP
- Wide beam angle improves shallow water coverage.
- 20° tilted element suits high-deadrise hulls.
- Superior resolution through 150–250 kHz CHIRP.
- Compatible with Garmin, Raymarine, Simrad, and Furuno via Mix-N-Match plug.
- Made from durable stainless steel for longevity in saltwater environments.
With these features, it’s no wonder the SS175C is a top choice for professionals.
Maintenance Tips
To ensure long-lasting performance, the Airmar SS175C-20-HW CHIRP must be well-maintained. Corrosion, marine growth, and electrical faults are common issues if not handled properly. Follow these key tips:
- Monthly Cleaning: Scrub marine growth with a soft brush and mild soap.
- Annual Inspection: Check tilt alignment and waterproof seal integrity.
- Connector Protection: Use dielectric grease on plug connections.
- Hull Check: Ensure no leaks or hairline cracks around the fitting.
Also, always check firmware compatibility and transducer readings via your sonar software for optimal calibration.

Comparing Airmar SS175C-20-HW CHIRP With Other Models
The SS175C is part of Airmar’s elite CHIRP series. Unlike traditional 600W or 1kW transducers, it operates with enhanced frequency modulation, allowing unparalleled detail. Compared to similar models like the SS164 or B175H-W:
- SS175C has better beamwidth and higher output clarity.
- SS164 supports dual frequency but lacks CHIRP depth.
- B175H-W is plastic-housed, whereas SS175C uses marine-grade stainless steel.
For detailed CHIRP and rugged durability, the SS175C wins hands-down.
Common Issues and Troubleshooting the Airmar SS175C-20-HW CHIRP
Like any marine electronic, even the best transducer can run into occasional problems. Here are common issues and how to troubleshoot them:
- No sonar reading: Check the plug connection and ensure the sonar unit is CHIRP-compatible.
- Erratic signals: May be caused by marine growth or cavitation; clean the housing.
- Low depth detection: Ensure tilt is correct and firmware is updated.
If issues persist, consult the OEM manual or connect with a service partner from Yamaha Outboards certified professionals.
Detailed FAQ Section
How do I install the Airmar SS175C-20-HW CHIRP transducer?
Installation should be handled by professionals due to the complexity of drilling through the hull. Begin by determining the hull’s deadrise and choosing the correct tilt. Use a hole saw to drill at the marked spot. Apply a marine-grade sealant around the transducer flange and insert it through the hull. From inside the hull, secure it using the provided nut, and tighten to the recommended torque specs. Connect the Mix-N-Match plug to your compatible sonar system. Always perform a dry run before sealing everything to verify alignment and compatibility.
Is the Airmar SS175C-20-HW CHIRP compatible with Garmin or Raymarine?
Yes, the transducer is designed with a Mix-N-Match plug system that enables compatibility with various CHIRP sonar modules including Garmin GSD, Raymarine CP470/CP570, and Simrad BSM-3. Ensure your device supports high-wide CHIRP frequencies (150–250 kHz). You may need an additional adapter cable depending on your system’s port configuration.
What makes the high-wide CHIRP different from low or medium CHIRP?
High-wide CHIRP provides a broader beam width—up to 25°—which increases your scanning area below the boat. This is especially useful for tracking fish schools and covering more territory in shallow waters. While low CHIRP reaches deeper waters and medium CHIRP offers a balance, high-wide CHIRP is preferred for its clarity and fish separation in coastal and inshore settings. The Airmar SS175C-20-HW CHIRP excels in this domain.
What is the lifespan and warranty of the Airmar SS175C-20-HW CHIRP?
Airmar transducers are built to last, especially those made from stainless steel like the SS175C. With proper installation and maintenance, the product can serve reliably for over 10 years. The manufacturer typically provides a 2–3 year limited warranty covering defects in materials and workmanship. Always register the product post-purchase to activate warranty benefits.
How much does the Airmar SS175C-20-HW CHIRP cost and is it worth it?
The Airmar SS175C-20-HW CHIRP typically ranges between $1,000 to $1,400 depending on the retailer and any ongoing promotions. For professionals or serious hobbyists who demand performance and accuracy, it’s well worth the investment. The wide scanning capability, enhanced CHIRP resolution, and durability ensure long-term value and reliable operation even under tough marine conditions.
Conclusion
In the world of marine navigation and sonar technology, the Airmar SS175C-20-HW CHIRP is a top-tier choice for any boater or angler demanding the best. From its rugged build to high-wide CHIRP clarity and sonar precision, it’s the ultimate tool to uncover what’s beneath your hull. Easy to integrate, professionally engineered, and built to last — this is your sonar system’s power amplifier.
