Raymarine SS75MW 1Kw 20Deg Tilt Wide Beam CHIRP Thru Hull

Unlock Superior Mid-Water Fish Detection with Advanced CHIRP Technology

Imagine gliding through open waters, your sonar screen lighting up with crisp images of schools of tuna or mahi-mahi suspended just below the surface. That's the edge the Raymarine SS75MW thru-hull transducer delivers. This powerhouse isn't your average depth finder—it's a game-changer for serious anglers chasing pelagic species in the upper to mid-water column. With its medium-frequency CHIRP range of 60-100 kHz and an ultra-wide beam, it paints a broader picture of what's lurking beneath, helping you spot fish targets with unmatched clarity and separation.

What sets this transducer apart is its tilted element design at a 20-degree angle. Mounted nearly flush to the hull, it compensates for deadrise angles up to 24 degrees, ensuring the ceramic element points straight down for optimal echo returns. No more dead zones or weak signals caused by hull angle mismatches. Pair it with compatible Raymarine multifunction displays, and you'll experience fast-response depth tracking down to 400 meters (1,300 feet), plus real-time water temperature readings to fine-tune your lure selection and trolling speeds.

Why Choose Medium-Wide Beam for Your Next Offshore Adventure?

The SS75MW's beamwidth expands dynamically from 57 to 73 degrees port-to-starboard and averages 16 degrees fore-to-aft across its 40 kHz bandwidth. This isn't just wide coverage—it's smart coverage. At lower frequencies, the beam widens for maximum under-boat sweep, ideal for scouting vast areas quickly. As frequencies climb, it narrows slightly for pinpoint precision on individual fish, reducing clutter from bait balls or thermoclines.

• Exceptional Fish ID: Superior target separation means distinguishing between a keeper snapper and a shad in seconds.
• Speed-Friendly Performance: Low-profile stainless steel housing minimizes drag and maintains resolution even at planing speeds when installed correctly.
• Versatile Pairing: Combine with low or high-frequency transducers for full-spectrum coverage from deep bottom dwellers to surface roamers.
• Rugged Build: Urethane acoustic window and 1 kW power rating handle rough seas and long-range pulses without flinching.

Anglers targeting species like kingfish, billfish, or amberjack swear by this setup. Its Exclusive Xducer ID technology simplifies integration, auto-detecting the transducer for plug-and-play ease on Raymarine systems.

Key Specifications at a Glance

Note: Suitable for hulls up to 11 m (36 ft) LOA, with a 95 mm (3-3/4 in) installation hole. Functions include depth and temperature sensing across -10°C to 40°C water temps.

Installation Insights for Peak Performance

Getting the most from your SS75MW starts with smart placement. Aim for the forward third of the hull, away from strakes, thru-hulls, or prop wash. The tilted element shines on V-hulls with moderate deadrise—use a fairing block if needed for flatter sections. Seal the 3-3/4 inch hole with marine sealant, route the 30-foot cable cleanly, and test at various speeds. Pro tip: Fairing aligns the transducer parallel to water flow, boosting high-speed readings by up to 20% in real-world tests.

Once installed, tweak your CHIRP settings for the water column you're fishing. Narrower sweeps for wrecks, wider for open water searches. This transducer thrives in coastal to bluewater scenarios, where mid-depth performance bridges the gap between shallow highs and abyss-diving lows.
