Airmar UST850 Smart Sensor NMEA 2000 - Plastic Housing

The Airmar UST850 Smart Sensor NMEA 2000 with plastic housing delivers professional-grade depth, temperature, and speed data to your marine electronics system with reliable accuracy. Designed for serious anglers and boaters who demand real-time water column intelligence, this transducer integrates seamlessly into NMEA 2000 networked systems, feeding critical fish-finding and navigation information directly to compatible chartplotters and fish finders. Whether you're working shallow flats or deep offshore structure, accurate sonar data is the foundation of consistent fishing success.

Built with a durable plastic housing, this smart sensor transmits through NMEA 2000 protocol—the marine industry standard for multi-device communication—eliminating the need for dedicated single-line transducers and reducing cockpit clutter. The dual-frequency capability ensures you capture high-resolution bottom detail and fish marks across varying depths and bottom compositions, while integrated temperature sensing tracks thermoclines and seasonal patterns that influence fish behavior. Weighing just 4.4 pounds and measuring 10 x 9 x 12 inches, it mounts easily to existing through-hull or transom brackets without requiring a complete system overhaul.

This sensor is ideal for vessels running Garmin, Simrad, Lowrance, or other NMEA 2000-compatible systems where you need centralized data distribution across multiple displays and autopilot units. Installation requires a standard transducer bracket and NMEA 2000 backbone connection—no proprietary cables or specialized training needed. Boaters upgrading from legacy single-purpose transducers will appreciate the network flexibility and the ability to share real-time sonar data with chartplotters, autopilots, and redundant fish finders across the entire boat.
