Airmar SS175C-12-L 12d Tilt Low CHIRP with Navico 9-Pin

The Airmar SS175C-12-L 12° Tilt Low CHIRP with Navico 9-Pin is a professional-grade thru-hull transducer purpose-built for serious anglers and boaters who demand precise sonar imaging in freshwater and saltwater environments. This transducer delivers the high-frequency clarity and low-frequency power that working captains and tournament fishermen rely on to locate structure, mark thermoclines, and detect fish at depths that challenge standard equipment. Whether you're running a center console, cabin cruiser, or dedicated fishing platform, this Airmar unit integrates seamlessly with Navico-compatible chartplotters and fish finders.

Built with a dual-frequency Low CHIRP operating range of 40 kHz to 60 kHz, the SS175C-12-L achieves maximum depth performance to 2,500 feet—essential for offshore applications and deep-water lake systems. The 12-degree tilt transducer housing and integrated depth plus fast-response water-temperature sensor provide real-time thermal stratification data critical for targeting species that migrate with water column changes. At 1 kW output power, this transducer generates strong return signals even in challenging conditions: high-salinity environments, dense vegetation, or turbid water. The Navico 9-pin connector ensures direct compatibility with Garmin GPSMAP and other Navico-equipped systems without adapter complications.

Installation suits hull materials ranging from fiberglass to aluminum, though proper through-hull drilling and sealing are essential to prevent galvanic corrosion and water intrusion on salt-water vessels. The 11-pound unit balances sensitivity and durability—heavy enough to resist cavitation at high speeds, yet manageable for mounting on most 18–40-foot platforms. Anglers upgrading from single-frequency systems will immediately notice the improved target separation and bottom definition that CHIRP technology delivers, while boaters working coastal transition zones benefit from the temperature sensor's ability to pinpoint thermocline breaks where gamefish congregate year-round.
