Plastična prehodna sonda s konusnim snopom HIGH CHIRP, kot 12°, CPT-S, 10 m kabla

The Raymarine CPT-S plastic through-hull transducer with a 20° conical beam (A80448) is a technically sound solution for fiberglass boat owners with a more pronounced V-hull (deadrise of approximately 16–24°). Its 20° angle 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 well-suited to recreational or inshore 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, while requiring hull drilling, is the preferred method for achieving optimal sonar performance by eliminating interference from water turbulence often encountered with transom-mount transducers. It is critical to select a location where water flow is as undisturbed as possible. The plastic construction of this transducer limits compatibility to fiberglass hulls only, avoiding galvanic corrosion issues. For wooden or metal hulls, a bronze CPT-S transducer should be considered, as it offers 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 seafloor. 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 recreational boating and fishing.
