Raymarine CPT120 Thru Hull With High Speed Fairing Block

The Raymarine CPT120 Thru Hull With High Speed Fairing Block is a professional-grade bronze transducer engineered for serious anglers and boaters who demand reliable sonar performance across a wide range of vessel speeds. This through-hull transducer delivers the consistent bottom-reading accuracy and fish detection capability that experienced water sportsmen depend on when navigating shallow flats, deep offshore channels, or everything in between. Built by Raymarine, a leader in marine electronics, the CPT120 represents the kind of trusted hardware that survives years of saltwater exposure and delivers when conditions get challenging.

The bronze construction provides superior corrosion resistance in saltwater environments, critical for anglers operating in coastal and offshore waters where aluminum would degrade rapidly. The integrated high-speed fairing block is precision-engineered to minimize turbulence and acoustic interference across the full operational speed range, ensuring clean sonar data whether you're trolling at 2 knots or running at planing speed. This design eliminates the flutter and false readings that plague poorly faired transducers, allowing you to confidently identify structure, thermoclines, and fish signatures without second-guessing what's on your screen.

The CPT120 excels for anglers running center-console boats, recreational fishing vessels, and cruising sailboats where a through-hull installation provides optimal acoustic window and permanent mounting. Compatible with Raymarine fishfinder and chartplotter systems across multiple generations, this transducer integrates seamlessly into existing marine electronics networks. Professional installation is recommended to ensure proper hull sealing and fairing block alignment, guaranteeing years of maintenance-free operation and the sonar clarity you need to consistently find fish and navigate safely.
