Overview / What Is Airmar SS175C-20-MW

The Airmar SS175C-20-MW is a thru-hull CHIRP transducer that operates in the Medium CHIRP frequency band (85-135 kHz) with an ultra-wide beam angle for superior fish detection and bottom tracking. Its 20° tilt ensures an optimized signal path in deep-V hulls, enhancing performance and accuracy. The bare wire MMC connector makes it flexible for custom integrations, especially in commercial or DIY marine electronics systems.

Key specifications:

• Frequency Range: 85-135 kHz (Medium CHIRP)
• Beamwidth: Ultra Wide (26° to 17°)
• Tilt: 20° for deep-V hulls
• Installation: Stainless steel housing, thru-hull mount
• Connection: Bare Wire MMC (Mix-N-Match Cable)

This transducer is ideal for boats ranging from 25 to 40 feet, including sportfishing vessels, workboats, and cruisers.

Why Choose a 20° Tilt for Deep-V Hulls

The 20° tilt of the Airmar SS175C-20-MW is critical for deep-V hull boats. It ensures the transducer’s beam is perpendicular to the seabed, providing accurate depth readings and clear sonar returns. Without the proper tilt, sonar imaging can be distorted, making fish detection and bottom tracking less reliable.

The stainless steel housing provides durability against corrosion and impact, while the bare wire MMC allows connection flexibility for boaters using various brands of MFDs (Multifunction Displays).

Benefits of Medium CHIRP Ultra Wide Technology

The Medium CHIRP Ultra Wide technology gives the Airmar SS175C-20-MW an edge over traditional sonar systems. It offers superior target separation, deeper penetration, and a wider field of view. The wide beam ensures more area coverage under your boat, making it ideal for identifying fish schools and underwater structures.

Benefits include:

• Better Fish Detection: Easily distinguish between baitfish and game fish.
• Improved Bottom Tracking: Even in deep or rough conditions.
• Minimal Interference: Thanks to CHIRP’s continuous frequency sweep.

Maintenance Tips

Proper maintenance ensures your Airmar SS175C-20-MW 20d Tilt Medium CHIRP Ultra Wide With Bare Wire MMC remains in peak condition. Here are expert maintenance practices:

1. Regular Cleaning: Clean the transducer face monthly using mild soap and water. Avoid harsh chemicals that can damage the stainless steel housing.
2. Inspect Wiring: Check the bare wire MMC for corrosion or wear. Ensure secure, waterproof connections.
3. Anti-Fouling Coating: Apply approved coatings to prevent marine growth, which can degrade sonar performance.
4. Winterization: In cold climates, protect the transducer from freezing by draining water lines and storing electronics properly.

By following these tips, your Airmar transducer will deliver accurate readings and a longer service life.

How to Install Airmar SS175C-20-MW

Installing the Airmar SS175C-20-MW requires precision. It’s typically a professional job, but DIY enthusiasts can follow the manufacturer’s guidelines. Key steps include:

• Locate the optimal position on the hull’s bottom – typically near the keel.
• Drill the mounting hole at the 20° tilt angle; use marine sealant for waterproofing.
• Secure the transducer and connect the bare wire MMC to your MFD or sonar system.
• Test for signal clarity and proper power connections.

Note: Incorrect installation may void warranties or cause poor sonar performance.
