Depth/Temperature Sounder P319 (CP370 Connection)

Designed for Raymarine fishfinder systems, the P319 depth/temperature sounder is a 600 W through-hull plastic transducer. Operating at 50 kHz and 200 kHz frequencies, it is specifically suited for direct connection to Raymarine CP370 digital sounder modules. This setup ensures reliable readings of water depth and temperature, essential for navigation and recreational fishing.

Positioning and compatibility

The P319 sounder positions itself as an economical and high-performance solution for fiberglass-hulled vessels. Unlike bronze transducers such as the B744V, the P319 model offers a plastic alternative, more affordable and reducing the risks of galvanic corrosion inherent to bronze transducers. Its compatibility with the Raymarine CP370 sounder module stands out for its plug-and-play integration, ensuring reliable integration with the CP370 digital sounder module. While the P319 is a fixed dual-frequency transducer (50/200 kHz), it integrates seamlessly with the CP370’s capabilities, which deliver superior target clarity and separation compared to traditional fishfinders.

Applications and technical performance

With its 50 kHz and 200 kHz frequencies, the P319 sounder is suited to a variety of applications. The 50 kHz frequency is relevant for detecting deeper seabeds and locating fish at greater depths, while the 200 kHz frequency offers better resolution for fish detection and seabed structure in shallower waters. This through-hull transducer requires a hole in the hull for installation, ensuring optimal exposure to water flow for accurate depth and temperature measurements. The P319 is a standard option for recreational boaters seeking a reliable solution without the installation constraints of internal transducers (such as the P79) or the cost of bronze transducers.
