Upgrade your boating experience with the Raymarine CPT-S thru-hull transducer, a powerhouse for anglers and navigators seeking crystal-clear underwater visuals. Crafted with a durable bronze housing, this 12-degree angled model thrives in saltwater environments, delivering reliable high CHIRP sonar performance without the bulk of traditional fairing blocks. Its low-profile design slips seamlessly through the hull, maintaining sleek lines while capturing data up to 900 feet deep.

Superior Sonar Imaging for Every Voyage

At the heart of this transducer lies advanced high CHIRP technology, pulsing a 25-degree conical beam that paints detailed pictures of fish schools, structure, and bottom contours. Unlike fixed-frequency sonars, CHIRP sweeps across a broad range of frequencies, offering unmatched target separation and sensitivity. Whether you're trolling for trophy fish in deep offshore waters or mapping shallow reefs, this unit excels at revealing what's below—even at high speeds where other transducers falter.

Integrated seawater temperature sensing adds another layer of utility, helping you pinpoint baitfish hotspots by tracking thermal shifts. Mariners love how it feeds precise data directly to Raymarine Element and Axiom displays, turning raw sonar into actionable insights for safer, more productive outings.

Effortless Installation on 12-Degree Hulls

Designed for hulls with 7 to 17-degree deadrise angles, the 12-degree tilt ensures optimal beam projection without dead zones or distortion. Skip the fairing block hassle—its streamlined shape minimizes drag and turbulence. The included 33-foot cable reaches most helm stations, and the bronze construction resists corrosion for years of saltwater service.

• Thru-hull mounting for clean, permanent installs
• No tools needed for basic setup beyond hull drilling
• Compatible with boats from center consoles to sportfishers

Pro tip: Pair it with anti-fouling paint on the face to keep marine growth at bay, extending peak performance between haul-outs.

Seamless Integration with Raymarine Systems

This CPT-S model shines brightest when networked with compatible Raymarine multifunction displays and modules. It supports CP100 and select MFDs ending in axx8 or esxx8, plus Axiom Pro S series via an optional adapter. Ensure your software runs version 16 or later for full CHIRP functionality. Note that it's dedicated to high CHIRP fishfinding—DownVision requires separate transducers.

Skip it for Dragonfly units; instead, it's ideal for upgrading older setups to modern sonar clarity.

Built to Last in Harsh Marine Conditions

Bronze isn't just for looks—it's engineered for toughness against electrolysis and biofouling common in marine settings. Backed by a solid warranty, this transducer delivers peace of mind on extended cruises. Regular hull cleaning and secure cabling prevent common issues, keeping readings sharp season after season.

Anglers report spotting fish in clutter-filled wrecks that older sonars missed entirely, while cruisers appreciate the depth reliability for anchoring in unfamiliar bays.
