Raymarine ST900/P120 Speed and Temperature Thru-Hull Transducer with Retractable Design and 45 ft Cable

ST900/P120 Speed Temp Thru-Hull Transducer Retractable with 13.7M (45) Cable

Speed performance has been taken to the next level with the ST900 Speed/Temperature sensor. Featuring the new Gen2 Paddlewheel, the ST900 outperforms all other paddlewheel sensors for responsive startup and linearity. The Gen2 Paddlewheel begins delivering accurate speed reporting as low as 0.3 knots and maintains smooth speed output through 45 knots.

Available with a plastic or bronze transducer housing, they sit nearly flush with the boats hull and minimize drag with only 5mm (3/16) extending outside the hull. The housing has a valve assembly that helps to minimize water ingress in the bilge when the sensor is removed for routine maintenance of the paddlewheel.

Features:

• Speed and fast-response water temperature sensor
• Analog output for use with Raymarine instruments like i40, i50, iTC-5, and legacy systems
• Retractable for easy maintenance
• ST900 transducer core is retrofittable into existing Airmar P120 and B120 transducer housings

Enhance your marine navigation with the Raymarine ST900/P120 Speed and Temperature Thru-Hull Transducer, engineered for precise and reliable performance. Featuring the advanced Gen2 Paddlewheel technology, this transducer delivers rapid and accurate speed measurements starting as low as 0.3 knots, maintaining consistent output up to 45 knots. Its responsive design ensures smooth and linear speed data for optimal boat control and navigation. The sensor's robust construction includes a low-profile, nearly flush mounting design with a 5mm (3/16 inch) extension outside the hull, reducing drag and improving hydrodynamics. Available with either a durable plastic or corrosion-resistant bronze housing, it is suitable for various hull materials, including fiberglass and metal, ensuring versatile installation options. The transducer is equipped with a valve assembly that minimizes water ingress during routine paddlewheel maintenance, simplifying upkeep and prolonging device lifespan. The 13.7-meter (45-foot) cable allows flexible installation, and the transducer's compatibility with existing Raymarine instruments such as i40, i50, and iTC-5 makes it an excellent retrofit choice. The retractable feature facilitates easy maintenance, ensuring your device stays in optimal condition without complex disassembly. Designed to record both speed and water temperature, the Raymarine ST900/P120 provides vital data for navigation, fishing, and boating activities. Its user-friendly design and high performance make it a reliable addition to any vessel seeking precise, real-time water data. Please note, the manufacturer states this product complies with PROP 65 regulations to ensure safety and environmental standards are met.
