It is particularly effective for offshore trolling, where the wide beam ensures coverage of large fish-holding areas. Anglers targeting mid-water column species such as tuna, mahi-mahi, or kingfish benefit from the Medium CHIRP’s ability to distinguish individual targets within dense bait schools.

Additionally, this transducer is a perfect match for deep-structure enthusiasts focusing on wrecks, reefs, or submerged ledges. Its superior target separation allows for precise jigging or bottom fishing, giving anglers a significant advantage. Commercial vessels involved in fish finding or seabed surveying also appreciate its wide coverage and reliable data accuracy.

Maintenance Tips

Ensuring the longevity of your Airmar SS175C-20-MW Furuno 12-Pin MMC involves regular maintenance. Start with routine cleaning of the transducer face to remove marine growth, debris, or salt deposits. Use a soft cloth or sponge with mild, non-abrasive cleaning solutions. Avoid harsh chemicals that could degrade the housing materials.

Periodically inspect the cable for signs of wear, cuts, or corrosion, particularly around the 12-Pin MMC connector. Applying anti-fouling paint (approved for transducers) can help reduce biofouling in marine environments. Schedule an annual inspection by a marine technician, especially if your vessel operates in extreme saltwater conditions. Regular upkeep will preserve sonar clarity and extend the life of your investment.

Troubleshooting Airmar SS175C-20-MW Furuno Sonar Issues

Encountering sonar inconsistencies with your Airmar SS175C-20-MW Furuno 12-Pin MMC? Begin troubleshooting by verifying transducer alignment and installation integrity. Air gaps, turbulence interference, or improper tilt adjustments often cause sonar signal dropouts or inaccurate readings.

Ensure that the MMC connection is secure, dry, and free from corrosion. Software glitches in Furuno MFDs can also disrupt sonar feedback — updating to the latest firmware version is recommended. Electromagnetic interference from onboard electronics is another culprit; maintain sufficient separation between power cables and transducer wiring. Persistent issues may necessitate professional diagnostics or component replacement.

Expert Advice and Pro Recommendations

Marine experts unanimously recommend pairing the Airmar SS175C-20-MW Furuno 12-Pin MMC with Furuno TZtouch3 or NavNet MFD series for seamless integration and optimal sonar processing. For offshore anglers, ensuring a clean hull surface and avoiding placement near thru-hull fittings is crucial for uninterrupted sonar imaging.

It’s also advised to opt for professional installation if you lack experience with thru-hull transducer mounting. Proper sealing and cable routing are essential to avoid water ingress and signal degradation.
