Overview / What Is Airmar SS175C Si-Tex 8-Pin
The Airmar SS175C Si-Tex 8-Pin is a thru-hull CHIRP-ready transducer that delivers High Wide sonar imaging for boats using Si-Tex sonar displays. The unit is ideal for inshore, nearshore, and even offshore fishing up to 500 meters deep. Its advanced CHIRP technology provides superior target separation and bottom tracking even at high speeds.
This specific model has a 20° tilt, making it perfect for vessels with steep deadrise hulls. The High Wide beam ensures a broader coverage area, giving anglers more detailed fish arches and consistent echo returns.
- Installation Type: Thru-Hull Bronze
- Connector Type: 8-Pin Si-Tex compatible
- Frequency Range: High CHIRP (150–250 kHz)
- Max Depth: Up to 500 meters
- Tilt: 20 degrees for optimal bottom contact
Benefits of High Wide CHIRP Technology
CHIRP (Compressed High-Intensity Radiated Pulse) transducers like the Airmar SS175C Si-Tex 8-Pin work by sweeping across a range of frequencies instead of sending a single ping. This results in much higher resolution and clarity in underwater imaging.
The High Wide frequency range (150–250 kHz) is especially beneficial for shallow to mid-depth applications and excels in distinguishing between fish targets, bait balls, and structure. This is invaluable for sportfishing and even commercial applications that require pinpoint precision.
How to Install Airmar SS175C Si-Tex 8-Pin
Proper installation is key to achieving the best performance from your Airmar SS175C Si-Tex 8-Pin transducer. It is a thru-hull model, so drilling through the hull is required. Here are the general steps:
- Select an appropriate mounting location, avoiding turbulence zones like near the keel or strakes.
- Drill a clean, vertical hole based on the transducer’s size specification.
- Apply marine-grade sealant and secure the transducer with its bronze housing.
- Route the cable securely to your Si-Tex display and connect via the 8-pin plug.
It is highly recommended to consult a certified marine installer for optimal placement and performance.
Durability and Cost Efficiency
Built with high-quality bronze, the Airmar SS175C Si-Tex 8-Pin is designed to withstand harsh saltwater environments for years. The unit is pressure-rated and vibration-resistant, making it a cost-effective long-term investment compared to plastic alternatives that degrade over time.
While the upfront cost may be higher than standard sonar transducers, the superior target separation, reduced signal noise, and lower need for replacements or upgrades make it a favorite among pros.
Maintenance Tips
Maintaining your Airmar SS175C Si-Tex 8-Pin is crucial for long-term performance and durability. Below are proven practices:
- Inspect the bronze housing every 3–6 months for signs of corrosion or marine growth.
- Clean the transducer face with a soft brush and mild soap—never use harsh abrasives.
- Ensure the 8-pin connector is dry, free from salt deposits, and properly seated into the Si-Tex sonar unit.
- Apply dielectric grease annually to the connector to protect from moisture ingress.
Proper maintenance ensures accurate readings and minimizes repair costs over time.
Expert Advice and Pro Recommendations
For the best results, pair your Airmar SS175C Si-Tex 8-Pin with a compatible Si-Tex CHIRP sonar unit. This transducer is most effective on boats with a 16–24 degree deadrise thanks to its 20° tilt, offering ideal bottom tracking.

Detailed FAQ Section
What boats are best suited for the Airmar SS175C Si-Tex 8-Pin?
This transducer is ideal for powerboats between 25–50 feet, especially those used in deep-sea or offshore fishing. Boats with 16°–24° deadrise are perfect due to the 20° internal tilt, allowing the sonar beam to shoot straight down for maximum bottom contact. Whether you’re trolling at slow speeds or cruising at 30+ knots, this unit maintains a strong bottom lock and clear fish arches.
Can I install the Airmar SS175C Si-Tex 8-Pin on my own?
While technically possible, a DIY installation of this thru-hull transducer is not recommended unless you have advanced marine electrical and hull modification experience. Incorrect placement or sealant usage could lead to leaks and sonar distortion. It’s best to hire a certified technician for professional installation.
How does High Wide CHIRP benefit saltwater fishing?
The High Wide frequency band (150–250 kHz) provides broader coverage, allowing you to scan more water. This is essential in saltwater where baitfish and predators often spread across large areas. The CHIRP capability enables target separation, so you can see fish above structures or tightly grouped together. It also reduces clutter from plankton and turbulence.
What makes the Airmar SS175C more reliable than other models?
Its solid bronze construction, waterproof Si-Tex 8-pin connection, and high-power CHIRP output make it one of the most durable and precise transducers available. The 20° tilt ensures accurate bottom tracking on steep deadrise hulls, while the wide beam maintains target integrity over a broader area. These features significantly reduce the chances of signal dropouts and misreads.
Is this transducer compatible with older Si-Tex units?
Compatibility depends on the CHIRP frequency support of your Si-Tex display. While most newer models are plug-and-play with this 8-pin unit, some legacy systems may require an adapter or firmware upgrade. Always confirm with Si-Tex or consult your marine electronics technician before purchasing.
Conclusion
The Airmar SS175C Si-Tex 8-Pin sets a high benchmark for sonar performance, installation integrity, and long-term reliability. Whether you’re fishing recreationally or working in commercial navigation, this transducer ensures precision, clarity, and confidence on every trip. Designed for serious marine enthusiasts, it’s a must-have for anyone demanding top-tier underwater imaging.
