Detailed description

Designed for water speed measurement, the Raymarine ST900/P120 V/T analog speedo (reference E70673) provides a dedicated solution for Raymarine navigation systems. This instrument offers direct and constant reading of essential data for navigation. It targets recreational boaters seeking reliable and specific instrumentation to display speed and water temperature.

Dedicated instrumentation and through-hull transducer

The Raymarine ST900/P120 V/T analog speedo consists of an analog display and a P120 V/T through-hull transducer. This transducer, typically made of plastic for installation on fiberglass or wooden hulls, is designed to measure speed through water and temperature. The kit includes a 13.7-meter cable, facilitating installation and connection of the transducer to the display unit.

Positioning within the Raymarine range

The ST900 fits into Raymarine’s line of dedicated instruments for specific functions. It offers an alternative to more complex multifunction displays by providing clear and instant information. Unlike newer series such as the i50 or i60, which feature digital interfaces and NMEA 2000 integration, the ST900 is designed as a standalone instrument, ideal for replacing or expanding existing Raymarine systems that prioritize analog display simplicity. This model is a relevant option for vessels that do not require extensive network integration but value immediate access to speed and water temperature data.

Expert opinion

« Technical analysis: Raymarine ST900/P120 V/T analog speedo »

The Raymarine ST900/P120 V/T analog speedo is a functional solution for measuring speed and water temperature on vessels requiring dedicated instrumentation. It integrates with existing Raymarine systems, providing direct and constant readings without the complexity of a digital network.

Its P120 V/T through-hull transducer, supplied with a 13.7 m cable, requires permanent installation and careful selection of the hull penetration location for optimal performance. This setup is particularly suitable for sailboats or powerboats prioritizing the reliability of analog data and the simplicity of a standalone instrument.

Unlike modern multifunction displays, the ST900 offers a clear and instant speed interface. It is ideal for complementing an existing dashboard or replacing a defective instrument of the same series, ensuring compatibility with older Raymarine systems. It is not suitable for fully digital NMEA 2000 installations without the addition of specific converters.
