Raymarine CPT-120 Bronze Thru Hull w/Fairing Block

Unlock Crystal-Clear Underwater Views with the Raymarine CPT-120

Imagine gliding across the water, your boat cutting through waves effortlessly, while a high-definition image of the seafloor unfolds on your display. That's the power of the Raymarine CPT-120 Bronze Thru-Hull Transducer with Fairing Block. Designed for serious boaters and anglers who demand precision, this transducer combines CHIRP fishfinding technology with wide-beam DownVision imaging. Mounted directly through your hull, it delivers real-time depth readings, temperature data, and stunning clarity—without the interference of in-hull or transom mounts.

Crafted from durable bronze, it's built to withstand the punishing marine environment, from salty ocean spray to freshwater lakes. Whether you're chasing trophy fish in deep waters or navigating rocky shallows, this thru-hull setup ensures reliable performance hull after hull.

Superior Performance Specs That Matter on the Water

The CPT-120 stands out with its impressive capabilities tailored for real-world boating. It probes depths up to 600 feet for DownVision imaging—perfect for spotting structure and baitfish—and reaches 900 feet for traditional CHIRP fishfinding. The dual-beam design offers a narrow 25-degree beam for pinpoint targeting and a wide 60-degree sweep for broad coverage.

• Thru-Hull Mounting: Optimal signal transmission through fiberglass or wood hulls with 0-25 degree deadrise.
• Bronze Construction: Corrosion-resistant for long-term reliability in harsh conditions.
• Extended Cable: 33 feet (10 meters) of marine-grade cabling gives you flexibility during installation.
• High-Speed Fairing Block: Streamlines water flow to minimize drag, ideal for planing hulls pushing speeds.

These specs translate to fewer false readings and more fish in the livewell, helping you make informed decisions when it counts.

Seamless Integration with Your Raymarine Gear

Pair the CPT-120 with your CP100, a68, or a78 displays for instant access to layered sonar views. The CHIRP DownVision element paints hyper-realistic images of the bottom, revealing wrecks, drop-offs, and weed beds that traditional sonar misses. Meanwhile, the fishfinder channel locks onto targets with exceptional separation, even in thermoclines or heavy cover.

Boaters upgrading from basic transducers often rave about the leap in detail—it's like switching from black-and-white TV to 4K. This compatibility keeps your setup future-proof within the Raymarine ecosystem.

Why Thru-Hull with Fairing Block Beats the Rest

In a sea of transducers, thru-hull models like the CPT-120 excel by sitting flush with the hull, free from bubbles and turbulence that plague transom mounts at speed. The included fairing block angles the unit perfectly, reducing resistance so you maintain hull speed without sacrificing sonar quality.

For offshore adventures or tournament fishing, this means consistent bottom lock from trolling to trolling motor speeds. Plus, its rugged build shrugs off impacts from debris, ensuring season-long dependability without constant checks.

Pro Tips for Peak Performance and Longevity

To get the most from your CPT-120, consider hull prep: a clean, fair deadrise ensures the best acoustic coupling. During installs, route the cable away from engines and props to dodge interference. On the water, calibrate sensitivity for your conditions—dial it back in murk for cleaner images.

Maintenance is straightforward: rinse with fresh water after saltwater use, inspect the face for marine growth, and store dry in off-seasons. This simple routine maximizes its lifespan, backed by Raymarine's commitment to quality.
