Designed for serious offshore anglers and recreational boaters alike, this high-wide (HW) CHIRP model offers unmatched target separation, reliable depth tracking, and enhanced fish detection. Whether you’re navigating coastal waters or exploring offshore wrecks, this transducer ensures optimal performance thanks to its fixed 12-degree tilt and CHIRP technology.
This blog will provide an in-depth breakdown of the Airmar SS175C 12d HW CHIRP with No Connector, how it works, maintenance best practices, expert recommendations, frequently asked questions, and a special discount just for you.
Overview / What Is Airmar SS175C 12d HW CHIRP with No Connector
The Airmar SS175C 12d HW CHIRP with No Connector is a top-tier thru-hull transducer crafted specifically for high-performance marine electronics. It belongs to Airmar’s high-wide CHIRP series, which transmits across a wide frequency range (150–250 kHz), giving you exceptional bottom definition and wide coverage areas. It uses a 12-degree tilted element to optimize sonar beam for deep-vee hulls without requiring a fairing block.
This unit doesn’t include a connector, allowing boat owners or installers to customize terminations to suit their system, especially in integration with multi-brand displays or custom harness setups. The solid stainless steel housing is built for durability and long-term marine exposure.
How Airmar SS175C 12d HW CHIRP Technology Works
CHIRP stands for Compressed High-Intensity Radiated Pulse. Instead of using a single frequency, the Airmar SS175C 12d HW CHIRP with No Connector sweeps through a continuous range of frequencies. This allows the transducer to send back cleaner, more detailed sonar images, reducing clutter and increasing target separation, even at greater depths.
By combining CHIRP and high-wide beam properties, this unit delivers broad coverage, which is ideal for locating baitfish or gamefish. Its fixed 12-degree tilt keeps the beam perpendicular to the sea floor at most hull deadrises, maintaining clarity and consistency in the sonar image.
Key Features of Airmar SS175C 12d HW CHIRP
- High-Wide CHIRP Frequency Range: 150 kHz–250 kHz for wide beam sonar coverage
- 12-Degree Tilt: Perfect for deep-vee hulls (16°–24° deadrise)
- No Connector: Offers customization flexibility for installers and multi-display environments
- Stainless Steel Housing: Built for rugged use and long-term corrosion resistance
- Maximum Depth: 600 feet (183 meters)
Installation Best Practices for Airmar SS175C 12d HW CHIRP
Proper installation is crucial for the Airmar SS175C 12d HW CHIRP with No Connector to perform optimally. Here are some key installation tips:
- Position the transducer on a flat section of the hull near the keel and away from turbulence-producing elements like strakes or through-hull fittings.
- Use a marine-grade sealant around the flange for watertight sealing.
- Since this model has no connector, make sure the cable end is correctly terminated per your marine display’s wiring specifications.
- Mount the unit with the arrow facing forward to align with the hull’s centerline.
If you’re unsure, professional installation is recommended to avoid sonar blind spots or signal distortion.
Maintenance Tips
Maintaining your Airmar SS175C 12d HW CHIRP with No Connector ensures long-term performance and durability. Here’s what you need to do:
- Inspect Regularly: Examine the transducer for marine growth, corrosion, or cracks every 3–6 months.
- Clean with Care: Use a non-abrasive cloth or sponge with mild soap to clean the housing. Avoid harsh chemicals or abrasive pads.
- Check Cabling: Ensure that the cable is properly shielded and there are no exposed or frayed wires, especially since this model doesn’t come with a standard connector.
- Dry Docking: When dry-docking your boat, inspect and clean the transducer before relaunching.
Understanding Beamwidth and CHIRP Sensitivity
One of the strongest features of the Airmar SS175C 12d HW CHIRP with No Connector is its wide beamwidth (25° average). This translates into broader area scanning, which is particularly useful for tracking schools of fish, bait, or mapping structure under your vessel.
Moreover, the high-frequency range provides superior resolution. This means you’ll not only detect fish, but also distinguish between species based on size and spacing—something traditional sonar simply cannot achieve. For gamefishers, this is a game-changer.
Cost and Durability of Airmar SS175C 12d HW CHIRP
The cost of the Airmar SS175C 12d HW CHIRP with No Connector is justified by its longevity and functionality. Unlike budget transducers that may fail after a few seasons, this model is built to last and provide consistent returns for years.
With a stainless steel housing, there’s minimal risk of corrosion or wear. And since it lacks a pre-attached connector, you can re-terminate the cable if necessary — extending the transducer’s usable life even further.
Expert Advice and Pro Recommendations
Marine electronics professionals often recommend the Airmar SS175C 12d HW CHIRP with No Connector to boaters who:
- Regularly fish offshore and need dependable depth tracking
- Use multi-display setups across different brands
- Prefer customized wiring installations without being locked into one plug system
For the best performance, pair this transducer with a CHIRP-capable sonar unit from Garmin, Simrad, or Raymarine. If unsure about compatibility or installation, we recommend visiting Yamaha Outboards for marine tech assistance.

Detailed FAQ Section
How do I install the Airmar SS175C 12d HW CHIRP with No Connector?
Installing the Airmar SS175C 12d HW CHIRP involves positioning it near the keel on the boat’s hull. Since it lacks a connector, you’ll need to wire it directly into your compatible CHIRP-enabled fishfinder or sonar unit. It’s important to follow Airmar’s wiring guide for accurate terminations. Use marine-grade sealant and install flush to avoid air bubbles or turbulence. If unsure, seek help from a certified marine technician.
What type of boats is this transducer suitable for?
This transducer is ideal for fiberglass or metal hull boats with a 16° to 24° deadrise. It’s suited for offshore fishing vessels, sportfishing boats, and larger recreational crafts that require reliable sonar in deep waters. Its high-wide frequency range ensures wide-area scanning, perfect for open-sea navigation.
Can I use this transducer with Garmin or Simrad devices?
Yes, absolutely. However, since this model comes without a connector, you must manually terminate the wiring to match your Garmin, Simrad, or other CHIRP-compatible brand. Always double-check polarity and pinout configurations before connection. Consult your display’s manual or contact support for wiring guidance.
How long does the Airmar SS175C 12d HW CHIRP last?
With proper maintenance, this stainless steel transducer can last up to 10 years or more. The absence of a connector reduces points of failure. Regular cleaning, cabling checks, and dry-dock inspections can significantly extend its life. It’s a long-term investment for serious boaters.
Why choose a high-wide CHIRP transducer?
High-wide CHIRP transducers like the Airmar SS175C 12d HW CHIRP offer broader beam coverage and greater resolution. You get better target separation, improved bottom imaging, and increased visibility of bait balls and gamefish. For anglers targeting pelagics or structure-huggers, this can mean the difference between a successful trip and an empty cooler.
Conclusion
The Airmar SS175C 12d HW CHIRP with No Connector stands as a robust and high-performing solution for boaters seeking advanced sonar capabilities. Its wide frequency range, stainless steel housing, and custom wiring flexibility make it a favorite among offshore enthusiasts. From installation to performance, this transducer delivers exceptional value and reliability.
For those serious about sonar performance and adaptability, this is a worthy investment.
