The Airmar SS175C-20-L 20-degree tilt Low CHIRP transducer with Si-Tex 8-pin connector is a professional-grade sonar head designed for serious anglers and commercial boaters who demand reliable bottom detection and water column imaging. This transducer combines Airmar's proven engineering with Low CHIRP (Compressed High Intensity Radar Pulse) frequency technology, delivering exceptional clarity in freshwater and coastal saltwater environments. Whether you're targeting structure on inland lakes or navigating deep offshore grounds, the SS175C-20-L provides the real-time data needed to locate fish and hazards with confidence.
Rated at 1 kilowatt of output power, this transducer operates across a low-frequency range of 40 kHz to 60 kHz, enabling maximum depth performance down to 762 meters (2,500 feet)—exceptional reach for deep-water applications. The dual-channel Low CHIRP system sweeps across its frequency band rather than pulsing at a fixed point, dramatically improving target separation and reducing noise interference from other electronic equipment on your vessel. A fast-response integrated water-temperature sensor provides real-time thermal readings crucial for understanding fish behavior and seasonal migration patterns. The 20-degree beam angle offers a balanced cone that covers adequate bottom area while maintaining fine target definition, and the tilt-mount design allows flexible installation angles to optimize sonar coverage for your specific hull configuration and cruising speed.
The Si-Tex 8-pin connector format ensures broad compatibility with legacy and modern Si-Tex sonar units, making this transducer an ideal replacement or upgrade for established systems. Weighing 11 pounds, the stainless steel housing resists corrosion in salt environments while the through-hull or transom-mount design fits most fishing boats, work vessels, and research platforms. Installation requires a qualified marine electrician familiar with transducer impedance matching and connector pinout verification to maximize performance and protect your sonar head investment.
