Raymarine CPT-S Thru-Hull - High Chirp - Bronze - 12°

The Raymarine CPT-S Thru-Hull High Chirp Bronze 12° transducer is purpose-built for anglers and boaters who demand precision sonar performance without compromise. This bronze thru-hull transducer integrates seamlessly with Raymarine's CP100 and MFD Series multifunction displays, delivering the high-frequency chirp sonar technology that serious fishermen rely on to locate structure, baitfish, and gamefish in diverse water conditions. Whether you're fishing saltwater flats, coastal ledges, or freshwater lakes, this dedicated high-chirp unit provides the acoustic clarity needed to make informed decisions on the water.

Built from marine-grade bronze, the CPT-S thru-hull design resists corrosion and delivers consistent performance in harsh saltwater and brackish environments. The 12° cone angle provides optimal coverage for general-purpose fishing and navigation, striking a balance between wide-area target detection and precise bottom definition. Operating exclusively on high-chirp sonar frequencies, this transducer omits the downvision element found in multi-function units, focusing all processing power on traditional CHIRP performance. The compact 7 x 6 x 12-inch form factor makes installation straightforward on vessels ranging from center consoles to offshore cruisers, while the 3.9-pound weight ensures minimal hull stress and easy removal if needed.

This transducer works with CP100 displays and Raymarine MFD systems featuring the axx8 or esxx8 designation, as well as Axiom Pro S series units, making it ideal for retrofit applications and new installations alike. Professional guides, tournament anglers, and dedicated recreational boaters benefit most from dedicated high-chirp transducers when sonar purity and processing speed matter. Proper thru-hull installation—accounting for hull deadrise and water flow—ensures peak performance; consult your vessel's specifications and Raymarine documentation for optimal placement and mounting orientation.
