Raymarine ST900 Speed and Temperature Sensor
The Raymarine ST900 is a state-of-the-art speed and temperature sensor featuring a low-profile plastic housing. With an innovative Gen2 Paddlewheel design, it delivers exceptional responsiveness and accuracy in a range of boating conditions.
This sensor provides reliable speed readings from as low as 0.3 knots up to 45 knots, along with precise water temperature measurements. Its retractable insert and water valve assembly minimize water ingress during maintenance, making it a practical choice for both sailing and power boats.
The low-profile design is nearly flush with the hull, enhancing performance by reducing drag.
