Raymarine CPT-70 (A80278) is a low-profile plastic thru-hull CHIRP DownVision and traditional sonar transducer engineered for permanent installation on fiberglass, metal, or wood hulls. Designed with a streamlined housing that integrates seamlessly with its supplied high-speed fairing block (cuttable for deadrise angles up to 25°), it ensures smooth water flow across the face of the transducer to deliver crisp, photo-like underwater imaging even at higher cruising speeds. Equipped with dual-element CHIRP sonar, the CPT-70 simultaneously sweeps across a wide frequency spectrum for high-definition bottom structure details and precise target separation for fish detection.
