Plastic through-hull cone beam HIGH CHIRP transducer CPT-S, 10m cable

The Raymarine CPT-S through-hull plastic transducer with a 20° conical beam (A80448) is a technically sound solution for fiberglass boat owners with a pronounced V-hull (deadrise of approximately 16-24°). Its 20° positioning is a major advantage for hulls with a matching deadrise, as it compensates for the hull angle and ensures the sonar beam is projected vertically, maximizing echo return accuracy without requiring additional wedges. This model is particularly suited to recreational or coastal fishing vessels seeking high-quality CHIRP performance without the installation constraints or costs associated with bronze transducers for more demanding hulls.

The through-hull installation, though requiring hull drilling, is the preferred method for achieving optimal sonar performance by eliminating water turbulence interference often encountered with transom-mount transducers. It is critical to select a location where water flow is least disturbed. The plastic construction of this transducer is exclusively compatible with fiberglass hulls, avoiding galvanic corrosion issues. For wooden or metal hulls, a bronze CPT-S transducer should be considered, offering better compatibility and increased robustness. The 10-meter cable length provides sufficient flexibility for most installations, but careful routing is required to avoid electromagnetic interference.

This transducer, being a 20° CPT-S model, is specifically designed for hulls with a more pronounced deadrise, distinguishing it from 0° models (for flat hulls) or 12° models (for moderate deadrises, if available for other SKUs). It delivers excellent value for compatible Raymarine systems, particularly those using DownVision™ technology, by providing clear, detailed images of the seabed. However, for very deep-water fishing applications or extreme target detection requirements, more powerful and multi-element CHIRP transducers may be considered. The A80448 is a reliable and high-performing choice for navigation and recreational fishing.
