Raymarine ST900 Speed/Temp Low Profile Bronze Thru-Hull with 13.7m Cable

The Raymarine ST900 Speed/Temp Low Profile Bronze Thru-Hull with 13.7m Cable is a dual-function marine transducer designed for anglers, cruisers, and boaters who demand real-time water speed and temperature data at the helm. This retractable insert transducer fits flush through your hull in a low-profile bronze housing, making it ideal for vessels where traditional through-hull mounting space or aesthetics are a concern.

Built with corrosion-resistant bronze construction, the ST900 delivers industry-leading speed measurement across a 0.3 to 45-knot range (0.34 to 52 MPH / 0.55 to 83 KPH), ensuring pinpoint accuracy whether you're trolling at low speeds or running at wide-open throttle. The fast-response temperature sensor captures thermal changes instantly, critical for locating temperature breaks where gamefish congregate or avoiding dangerous thermocline transitions.

Analog output integration means compatibility with legacy Raymarine systems and other marine electronics, while the 13.7-meter (approximately 45-foot) cable provides flexible installation routing through your boat's core and into the pilothouse or console without signal loss. This transducer is best suited for retrofits on cruising sailboats, center-console boats, and displacement hulls, making it a versatile choice for various marine applications.
