Discover Superior Underwater Clarity with the SS175M Medium CHIRP Transducer
Upgrade your boat’s sonar capabilities with a rugged thru-hull transducer designed for serious anglers and commercial operators chasing fish in varied depths. This stainless steel powerhouse delivers crisp Medium CHIRP imaging that punches through water columns better than high-frequency options while sharpening targets sharper than traditional low-frequency setups. Perfect for vessels navigating coastal waters or inland lakes, it captures everything from bait schools to structure with remarkable detail.
Built to withstand harsh marine environments, the tilted element ensures optimal beam projection regardless of hull deadrise, minimizing dead zones and maximizing coverage directly beneath your boat. Whether you’re marking wrecks, tracking thermoclines, or spotting trophy fish, this transducer transforms your fishfinder display into a window into the deep.
Standout Features for Reliable Performance
Durable Stainless Steel Housing: Corrosion-resistant construction thrives on steel, aluminum, fiberglass, or wood hulls, handling constant exposure to saltwater and freshwater.
Medium CHIRP Technology (85-135 kHz): Sweeps across 50 kHz of bandwidth, hitting key fishing sweet spots like 88 kHz and 107 kHz for versatile target separation and depth penetration up to several hundred feet.
12-Degree Tilted Element: Precision-aligned for hulls with moderate deadrise, projecting a dynamic beamwidth from 24° at lower frequencies to 16° at higher ones for focused scanning.
Integrated Depth and Temperature Sensing: Real-time water temp data alongside high-resolution depth readings, essential for locating temperature breaks where fish congregate.
Extended 33-Foot Cable: Ample length for clean routing from the hull to your display unit, reducing signal noise.
9-Pin Black Connector: Seamless plug-and-play with compatible marine electronics.
Why Medium CHIRP Excels in Real-World Fishing
Unlike narrow high-CHIRP bands that excel in shallow crispness or broad low-CHIRP for extreme depths, Medium CHIRP strikes the perfect balance. Anglers report tighter fish arches, clearer bottom contours, and fewer false readings around bait balls. The 1 kW power handling supports high-output sounders, revealing subtle ledges and drop-offs that hold walleye, bass, or snapper.
For boats up to 36 feet, it mounts flush for hydrodynamic efficiency—no drag, no turbulence. The low-profile design (usable shaft around 2.8 inches) fits most transom setups without major hull modifications.
Effortless Installation and Long-Term Maintenance
Installing a thru-hull transducer like this one rewards careful planning. Select a spot forward of the prop and keel, away from strakes or thru-hulls that cause interference. Drill precisely, bed with marine sealant, and secure the nut hand-tight plus a quarter turn. Pair it with a fairing block for high-speed accuracy if your hull demands it.
Once in place, winterize by removing if possible, or flush the system. Regular hull cleaning prevents marine growth from attenuating signals, keeping readings sharp season after season. Pro tip: Calibrate temp and depth offsets in your unit’s menu for pinpoint accuracy.
Ideal Scenarios for Peak Fishing Success
Coastal salmon chasers love its resolution on downriggers. Great Lakes walleye pros rely on it for mid-depth jigging. Offshore bottom bouncers appreciate the steel housing punching through green water. Even tournament bass boats benefit from temp-sensing for post-frontal patterns. It’s not just gear—it’s your edge on the water.
