Airmar SS175C-20-MThru Hull 20 Deg Tilt Medium CHIRP with Navico BL

The Airmar SS175C-20-M through-hull transducer with Navico BL connector is a medium-frequency CHIRP sounder designed for serious anglers and recreational boaters who require precise fish-finding capabilities and reliable water-column imaging. This transducer helps eliminate guesswork when locating underwater structures, suspended baitfish, and bottom composition, which are essential for successful fishing trips.

Operating at medium frequencies between 85 kHz and 135 kHz, the Airmar SS175C-20-M features a 20-degree tilt housing and generates a beamwidth of 16 degrees to 11 degrees. It is rated at 1 kW of peak power and can operate at depths of up to 457 meters (1,500 feet), making it capable of penetrating thermoclines and harsh freshwater conditions while maintaining detail. The integrated depth and water-temperature sensors provide real-time environmental data, allowing users to adjust their fishing tactics based on current conditions.

This medium-format transducer is ideal for targeting various species, including walleye and stripers, and is suitable for both recreational and commercial fishing operations. Its CHIRP frequency-sweep technology distinguishes between bottom hardness, vegetation, and baitfish size more effectively than traditional single-frequency sounders, giving anglers the confidence to commit to structural targets.
