Raymarine ST950/P117 Speed/Temperature Long Body Retractable Through Hull Analogue Transducer - 10m Cable

Speed performance has been taken to the next level with the ST950 Speed/Temperature sensor. Featuring the new Gen2 Paddlewheel, the ST950 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 P17 plastic housing, the ST950 sits nearly flush to the boat's 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.

• 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
• ST950 transducer core is retrofittable into existing Airmar P17 and B17 transducer housings
