Raymarine CPT-120 (A80350) is a high-performance bronze thru-hull CHIRP DownVision and traditional sonar transducer engineered for permanent installation on fiberglass or wood hulls. Supplied with a high-speed fairing block (cuttable for deadrise angles up to 25°), it ensures smooth hydrodynamic water flow across the transducer face to deliver photo-like underwater imagery and clean bottom tracking even at higher cruising speeds. Featuring dual-element CHIRP technology, the CPT-120 sweeps across a broad frequency spectrum to provide detailed structural detail alongside clear target separation for fish detection.
