Raymarine P120-ST800 Thru-Hull Speed & Temp Transducer

The Raymarine P120-ST800 Thru-Hull Speed & Temp Transducer is purpose-built for serious anglers and boaters who demand accurate water speed and temperature data at their helm. Whether you're navigating shallow flats, running offshore, or threading coastal channels, this transducer delivers real-time readings that inform your fishing strategy and fuel management.

Installed below the waterline, it feeds critical performance metrics directly to compatible Raymarine systems, allowing you to monitor conditions without guesswork and adjust your approach on the water. The P120-ST800 combines a dual-function design—water speed (paddle wheel) and temperature sensors—in a single thru-hull housing that minimizes drag and installation complexity. Manufactured to Raymarine's marine-grade standards, the transducer resists saltwater corrosion and maintains accuracy across freshwater and saltwater environments.

This transducer is ideal for boats already equipped with Raymarine electronics seeking to upgrade speed and temperature sensing capability. Installation requires a thru-hull fitting—a straightforward task for most boat owners, though professional installation is recommended to ensure proper sealing and cable routing. With its reliable output to your multifunction display or autopilot system, the P120-ST800 enhances your boating experience.
