Furuno SS75M Stainless Steel Thru-Hull Chirp Transducer - 12° Tilt - Med Frequency

Upgrade your vessel's sonar capabilities with the Furuno SS75M/12, a robust stainless steel thru-hull transducer engineered for serious boaters chasing clarity beneath the waves. This medium-frequency CHIRP powerhouse delivers exceptional target separation and depth penetration, turning murky waters into a detailed underwater map. Whether you're scanning for structure on your next fishing expedition or navigating challenging seabeds, its 12-degree tilt design ensures optimal beam projection even on hulls with moderate deadrise angles.

Superior Performance in Demanding Conditions

Crafted from durable stainless steel, the SS75M/12 withstands the harsh marine environment while providing reliable depth and temperature readings. Operating across a broad 80-130 kHz CHIRP spectrum, it adapts to varying conditions, offering beam widths that narrow from 24 to 16 degrees for pinpoint accuracy at greater depths—up to 900 feet. The 600-watt power handling means stronger signals and crisper returns, helping you distinguish fish from baitfish or debris with ease.

Boaters appreciate how this transducer minimizes interference from hull turbulence, thanks to its thru-hull mount and precise tilt correction for 8-15 degree deadrises. Paired with Furuno's renowned chartplotters and sounders, it unlocks wide broadband capabilities, revealing wrecks, drop-offs, and schools that narrower fixed-frequency units might miss.

Key Specifications That Matter

• Beam Coverage: 24° at 80 kHz to 16° at 130 kHz, balancing coverage and resolution
• Max Depth: 900 feet, ideal for offshore pursuits
• Power Output: 600 watts RMS for enhanced signal strength
• Connection: 10-pin connector with 39 feet of cable for flexible routing
• Sensors: Depth and water temperature for comprehensive data

Installation Insights for Peak Results

Mounting a thru-hull like the SS75M/12 rewards careful planning. Select a spot forward of the propellers, away from strakes or thru-hulls that could disrupt flow. Fairing blocks are often recommended to align the face perfectly perpendicular to the waterline, maximizing beam efficiency. Use marine sealant around the hull fitting to prevent leaks, and route the 39-foot cable neatly to avoid chafing. For hulls with 8-15 degree deadrise, the built-in 12° tilt gets you close—fine-tune with a custom fairing if needed. Test in shallow water post-install to confirm clear bottom tracking at all speeds.

Pro tip: Pair it with high-end Furuno displays supporting CHIRP to exploit its full dynamic range, where subtle echoes pop against noise.

Real-World Applications and Advantages

Anglers targeting mid-water pelagics love the SS75M/12's ability to lock onto thermoclines and bait balls without the wide-beam clutter of low-frequency options. Cruisers benefit from its temperature sensor for spotting current rips or upwellings. Compared to plastic housings, stainless steel shrugs off growth and impacts, extending service life in salty or debris-filled waters. It's not just gear—it's a tool that sharpens your edge on the water, delivering returns that feel almost intuitive after a few trips.
