Raymarine CPT-120 Bronze Thru Hull w/Fairing Block

The Raymarine CPT-120 Bronze Thru Hull with Fairing Block is a dual-frequency CHIRP transducer engineered for anglers who demand advanced subsurface imaging alongside traditional fishfinding capability. This bronze-hulled transducer pairs a conical CHIRP fishfinding element with Raymarine's proprietary DownVision wide-beam imaging system, delivering unrivaled clarity of structure, bottom composition, and fish positioning in a single installation.

The CPT-120 operates with a 25° narrow beam and 60° wide beam profile, allowing traditional fishfinding to penetrate to 900 feet maximum depth while the DownVision element maps subsurface features to 600 feet with exceptional lateral detail. The combination frequency design (CHIRP DownVision/DownVision/Fishfinder) allows you to toggle between modes on compatible Raymarine multifunction displays, optimizing for either deep offshore structure or high-resolution near-bottom imaging. Bronze construction is standard for salt-water installations, resisting corrosion in marine environments where aluminum or stainless alternatives may degrade. The included fairing block reduces drag and turbulence around the transducer, improving signal clarity and minimizing performance degradation at higher speeds.

This transducer is designed for fiberglass hull mounting and suits both offshore sport fishing vessels and serious cruising sailboats where dual-function sonar visibility is a priority. Weekend anglers benefit from the integration of fish-finding and bottom-mapping functions without running separate transducers, while professional charter and commercial operators leverage the high-frequency DownVision data for precise structure location and catch assessment. The CPT-120 integrates with Raymarine's Axiom, Element, and legacy multifunctions, making it a compatible upgrade for existing Raymarine systems.
