Designed for vessels operating in offshore conditions, this model offers a low-frequency CHIRP band (40-60 kHz) that penetrates deep waters with clarity and accuracy. It features a 12° tilted element, ideal for moderate deadrise hulls, and is paired with a convenient Raymarine 11-pin connector, enabling seamless integration with Raymarine MFDs and sonar modules.

With CHIRP technology, the Airmar SS175C Raymarine CHIRP delivers high-resolution sonar returns that separate individual fish targets from structures and clutter. It’s a premium choice for serious anglers, commercial vessels, and oceanographers who require advanced sonar performance. If you’re upgrading your marine electronics for deep-water reliability, this transducer deserves a close look.

Overview / What Is Airmar SS175C Raymarine CHIRP

The Airmar SS175C Raymarine CHIRP is a low-frequency (40–60 kHz) CHIRP transducer tailored for Raymarine systems. It’s engineered with a stainless steel housing and a 12° tilted ceramic element that matches hulls with a 8°–16° deadrise. The 11-pin Raymarine connector ensures direct plug-and-play compatibility with Raymarine’s CP470/CP570 sonar modules and Axiom series displays.

CHIRP (Compressed High-Intensity Radiated Pulse) technology continuously sweeps across frequencies instead of transmitting a single frequency pulse, which results in greater detail, better target separation, and enhanced bottom tracking. The Airmar SS175C-12-L is particularly effective in depths beyond 3000 feet, making it ideal for deep-sea fishing, drop-offs, or trench mapping missions.

How to Install Airmar SS175C Raymarine CHIRP

Installation of the Airmar SS175C Raymarine CHIRP transducer requires precision and expertise. The transducer is designed for a thru-hull setup, which involves drilling a hole at the boat’s keel with proper deadrise alignment. The 12° tilted element compensates for hull angle, keeping the beam aimed straight down without the need for a fairing block.

The Raymarine 11-pin connector simplifies electrical hookup, allowing easy integration with Raymarine sonar modules. Use marine-grade bedding compound for sealing and torque the retaining nut according to Airmar’s torque specs. It’s best to install during haul-out periods or with assistance from a certified marine electronics technician.

Why Low CHIRP is Ideal for Offshore Fishing

Low-frequency CHIRP (40–60 kHz) penetrates much deeper into the water column than high-frequency CHIRP. It is less affected by thermoclines and water turbidity, allowing anglers to detect targets in deep and murky waters. This is critical for species like swordfish or tuna that reside at depths exceeding 1000 feet.

With the Airmar SS175C Raymarine CHIRP, you can scan depths up to 3000 feet depending on conditions. It’s also excellent at identifying seabed hardness, structures, and large schools of fish. This makes it a must-have for commercial fishermen, ocean researchers, and deep-sea sportfishing enthusiasts.

Maintenance Tips

Maintaining your Airmar SS175C Raymarine CHIRP is essential to ensure it continues delivering accurate sonar results. Routine care helps prevent marine growth, electrical degradation, and mechanical issues.

• Clean the transducer face: Use a soft cloth and mild detergent to remove barnacles, algae, or salt deposits.
• Inspect the connector: Ensure the Raymarine 11-pin is free from corrosion. Apply dielectric grease for added protection.
• Monitor signal quality: If signal loss occurs, check cabling for wear or breaks and ensure tight sealing at thru-hull entry.
• Schedule annual inspections: During haul-out, visually inspect mounting, check torque, and clean or re-bond the unit if needed.

Following these transducer maintenance tips will extend your device’s life and maintain sonar clarity in demanding marine environments.

Expert Advice and Pro Recommendations

Marine electronics experts widely recommend the Airmar SS175C-12-L 12d Tilt Low CHIRP with Raymarine 11-Pin for boats operating in deep offshore areas. It pairs perfectly with the CP470 and CP570 CHIRP sonar modules, delivering unmatched bottom detection and target identification.

If your vessel’s deadrise is between 8° and 16°, this 12° tilt model is optimal. Use code WELCOME5 to receive 5% off your order and take advantage of the precision Raymarine integration. Always confirm compatibility with your sonar before purchasing for plug-and-play efficiency.

Best Airmar SS175C Raymarine CHIRP Options Compared

The SS175C lineup includes different tilt angles to accommodate varying hull deadrises. For instance, the 0° tilt version suits flat-bottomed hulls, while the 20° variant is for steeper deadrise boats. The 12° tilt, featured here, offers a versatile mid-range solution.

Raymarine users benefit greatly from the 11-pin connector integration, eliminating adapter needs and reducing setup time. When combined with dual-channel CHIRP sonar, the SS175C can scan both deep and shallow simultaneously. This makes it ideal for coastal transition zones or variable-depth terrains.

Airmar SS175C Raymarine CHIRP Troubleshooting Tips

Even the most reliable marine electronics can encounter issues. Here’s how to troubleshoot common problems with your Airmar SS175C Raymarine CHIRP transducer:

• No depth reading: Check the Raymarine 11-pin connector. Reseating or replacing may resolve the issue.
• Weak signal at depth: This can indicate a fouled face or improper installation angle. Clean and verify alignment.
• Intermittent sonar: Inspect the cable for damage or water ingress at the hull entry point.
• Compatibility error: Ensure your Raymarine display supports CHIRP and has the correct software update.

If these steps don’t work, contact Airmar or your Raymarine dealer for advanced diagnostics. Preventive care and regular inspection reduce the need for repairs.

Detailed FAQ Section

How does the Airmar SS175C Raymarine CHIRP differ from traditional transducers?

Unlike standard transducers, which operate at a single frequency, the Airmar SS175C Raymarine CHIRP transmits across a low-frequency band (40-60 kHz). This produces detailed, high-resolution sonar returns with better target separation and bottom tracking, even at depths of 3000 feet. The Raymarine 11-pin connector ensures plug-and-play setup with Raymarine systems, eliminating wiring guesswork. Its 12° tilt compensates for hull deadrise, making it one of the most efficient options for deep-sea sonar tracking.

What Raymarine systems are compatible with this transducer?

The Airmar SS175C Raymarine CHIRP works with Raymarine sonar modules such as the CP470 and CP570 and is fully compatible with Axiom Pro and Axiom XL MFDs. Its 11-pin connector ensures direct integration without requiring additional adapters. Always verify that your Raymarine system supports low CHIRP frequency and update firmware for optimal performance. Pairing with a dual-channel CHIRP module maximizes sonar returns for both shallow and deep targets.

Can I install the Airmar SS175C Raymarine CHIRP on my own?

Technically, yes—but it is recommended to hire a certified marine installer. The thru-hull installation requires drilling and sealing below the waterline, which must be done precisely. The 11-pin Raymarine connector simplifies electrical hookup, but aligning the transducer’s 12° tilt with the boat’s deadrise needs expert accuracy. Incorrect installation can result in sonar distortion, leaks, or poor depth tracking.

What is the durability and warranty of this transducer?

The Airmar SS175C Raymarine CHIRP is built with high-grade stainless steel and a robust ceramic element rated for deep water pressure. It resists marine corrosion and vibration, delivering consistent performance in harsh environments. With regular maintenance, the transducer typically lasts over 5–7 years. Airmar offers a limited warranty, usually ranging from 1 to 2 years. Warranty conditions may vary based on distributor or installer policy.

How do I maintain the Raymarine 11-pin connection?

To maintain a reliable connection, inspect the 11-pin plug regularly for corrosion or salt build-up. Apply dielectric grease to prevent moisture ingress. Never force the connector when inserting; ensure it’s aligned properly. During long periods of inactivity or storage, cover the connector with a protective cap. Avoid routing the cable in areas prone to chafing, and secure it with marine-grade clamps for long-lasting use.

Conclusion

The Airmar SS175C-12-L 12d Tilt Low CHIRP with Raymarine 11-Pin for Boats & Marine Engines delivers exceptional low-frequency sonar performance for deep water applications. With CHIRP technology and a 12° tilted design, it provides unmatched bottom tracking, target clarity, and long-range scanning.
