SKU: AIRSS175C20MBL
MPN: SS175C-20-M-BL
The Airmar SS175C-20-M through-hull transducer with Navico BL connector is a medium-frequency CHIRP sounder built for serious anglers and recreational boaters who demand accurate fish-finding performance and reliable water-column imaging. This transducer eliminates guesswork when locating structure, suspended baitfish, and bottom composition—critical factors that separate productive days on the water from long stretches of waiting. Whether you're targeting walleye in deep lakes, stripers in reservoirs, or managing a commercial fishing operation, this medium-format transducer delivers the precision needed to maximize time over fish.
Operating at medium frequencies between 85 kHz and 135 kHz with a 20-degree tilt housing, the Airmar SS175C-20-M generates a tight 16-degree to 11-degree beamwidth—ideal for pinpointing targets and reducing dead zones around your hull. Rated at 1 kW of peak power with a maximum operating depth of 457 meters (1,500 feet), this transducer penetrates thermoclines and harsh freshwater conditions without sacrificing detail. The integrated depth and water-temperature sensor provides real-time environmental data, enabling you to adjust tactics based on conditions. CHIRP frequency-sweep technology distinguishes bottom hardness, vegetation, and baitfish size far more effectively than traditional single-frequency sounders, giving you the confidence to commit to structural targets.
The 20-degree tilt mounting angle accommodates most hull designs without requiring extensive modification, and the Navico BL connector ensures plug-and-play integration with compatible Navico chartplotters and multifunction displays. Installation through the hull demands careful site selection and proper sealing, but once mounted, the transducer's robust stainless-steel construction resists saltwater corrosion and repeated freshwater cycles. This transducer suits anglers running aluminum center consoles, fiberglass cabin cruisers, and pontoon platforms where medium-frequency performance justifies the through-hull commitment over portable options.
