It is built for use with Raymarine CP100, a68, and a78 systems, and it suits hulls with deadrise angles from 0 to 25 degrees when installed with the supplied fairing block.\u003c\/p\u003e\u003cp\u003eThis transducer uses a 25-degree conical sonar beam and a DownVision fan beam that is wide from port to starboard and thin from fore to aft. The 10 m cable gives installers practical routing length for reaching the display or sonar module from a through-hull location, while the listed 210.8 mm length and 131.8 mm maximum height help with space checks before cutting the hull.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eThrough-hull CHIRP DownVision transducer for a fixed below-waterline sonar installation.\u003c\/li\u003e\n\u003cli\u003eDepth and temperature sensing in one transducer body, with no speed sensor included.\u003c\/li\u003e\n\u003cli\u003eCompatible with Raymarine CP100, a68, and a78 systems.\u003c\/li\u003e\n\u003cli\u003eWorks with hull deadrise angles from 0 to 25 degrees when installed with the supplied fairing block.\u003c\/li\u003e\n\u003cli\u003e25-degree conical sonar beam for standard fishfinder returns.\u003c\/li\u003e\n\u003cli\u003eDownVision fan beam gives a wide side-to-side view with a thin fore-and-aft profile for structure imaging.\u003c\/li\u003e\n\u003cli\u003eTypical depth performance is 189 m, or 600 ft, depending on installation, water conditions, and bottom type.\u003c\/li\u003e\n\u003cli\u003e10 m cable supports routing from the through-hull mounting point to the helm or sonar module location.\u003c\/li\u003e\n\u003cli\u003eApproximate transducer dimensions are 210.8 mm long by 131.8 mm maximum height.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe CPT-110 is intended for a permanent through-hull installation, so hull thickness, interior access, bilge clearance, cable routing, and the running surface of the hull should be checked before drilling. The supplied fairing block helps position the transducer correctly on hulls with deadrise, which matters for clean sonar returns while the boat is moving.\u003c\/p\u003e\u003cp\u003eMounting location has a direct effect on sonar quality. The transducer should sit in solid water flow, away from turbulence caused by strakes, through-hull fittings, steps, propellers, or aerated water. On planing powerboats, placement should be chosen with care so the face of the transducer can stay in usable water at the speeds where sonar performance is needed.\u003c\/p\u003e\u003ch6\u003eCompatibility and use on board\u003c\/h6\u003e\u003cp\u003eThis model is a practical match for boats using compatible Raymarine DownVision equipment where the owner wants a below-hull transducer rather than a transom-mount option. It fits fishing boats, cruisers, and trailerable boats where depth, bottom detail, and water temperature are useful for navigation, fishing, and reading bottom structure.\u003c\/p\u003e\u003cp\u003eThe 10 m cable is useful on installations where the sonar module or multifunction display is not close to the bilge area. As with any sonar installation, avoid routing the cable next to high-current wiring where possible, and leave enough service loop for inspection and future maintenance.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eAfter installation, keep the exposed transducer surface clean so growth, slime, or paint buildup does not block the sonar signal. Regular checks are especially important for boats kept in saltwater, warm-water marinas, or areas with heavy fouling. Inspect the through-hull area during haul-outs and confirm that the cable remains secure and protected inside the hull.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eRaymarine CPT-110 through-hull transducer\u003c\/li\u003e\n\u003cli\u003eFairing block\u003c\/li\u003e\n\u003cli\u003e10 m transducer cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Raymarine","offers":[{"title":"Default Title","offer_id":52715828609205,"sku":"QBP373114","price":374.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1340829_qbp373114.png?v=1781720200","url":"https:\/\/www.qualityboatparts.com\/products\/qbp373114","provider":"Quality Boat Parts","version":"1.0","type":"link"}
