Airmar SS175C-12-M 12d Tilt Medium CHIRP with Navico BL

The Airmar SS175C-12-M 12d Tilt Medium CHIRP with Navico BL is a professional-grade transducer designed for anglers and boaters who demand reliable depth sensing and water-temperature monitoring in freshwater and saltwater environments. After years on the water, serious fishermen understand that accurate sonar is non-negotiable—whether you're scanning structure, tracking thermoclines, or navigating shallow flats. This transducer integrates seamlessly with Navico sounder systems, making it an ideal choice for upgrading legacy equipment or building a new fish-finding suite on modern plotter packages.

Built around CHIRP (Compressed High-Intensity Radiated Pulse) technology, the SS175C-12-M delivers superior target separation and clutter rejection compared to conventional single-frequency sounders. Its medium frequency band operates between 40 kHz and 60 kHz, providing a beamwidth ranging from 32° to 21°, which balances wide coverage in shallow water with tight beam focus for deep structure definition—maximum operating depth reaches 762 meters (2,500 feet). The 1 kW power output ensures crisp signal return and excellent bottom definition, while the integrated tilt mount accommodates both through-hull and transom-mounted installations. The 11 lb weight is manageable for most hull configurations, and the dual-sensor design continuously monitors temperature stratification, a critical advantage when hunting seasonal fish patterns.

This transducer works best with Navico-compatible sonars including Simrad, B&G, and Lowrance systems, making it a go-to upgrade path for owners already invested in that ecosystem. Recreational and professional charter operators benefit from its robust construction and proven performance in variable salinity conditions. Transom and through-hull mounting options make it versatile across center consoles, bay boats, offshore platforms, and larger cruising vessels. Proper installation and cable management are essential—consult your sounder's documentation to confirm pin compatibility and ensure full CHIRP functionality.
