Airmar UST850 Thru-Hull Ultrasonic Smart Multisensor

Airmar's UST850 Smart Multisensor is a high-precision ultrasonic speed and temperature solution for power and sail boats of all types and sizes. This thru-hull sensor contains no moving parts, instead it uses Airmar's Smart™ technology to deliver finished data, ready for any navigational application.

Features:

• Ultrasonic speed and fast-response water-temperature sensor
• Provides precise readings at high speeds - ideal for powerboats, cruising, and sailing
• Advanced filtering and sampling rates for increased accuracy at all speeds
• Keeps speed accuracy consistent by adapting automatically to boat speed, water depth and water clarity
• Utilizes two ultrasonic transducers, to measure the time it takes for particles in the water to travel between them
• Thru-hull, low-profile housing with water valve
• No paddlewheel to clean or maintain - no moving parts to break or wear out
• Retractable insert for safe storage
• Retrofits to existing Airmar's P17 or B17 housings
• Includes Ultrasonic processor and blanking plug
