          Description

          Airmar's UDST800 Ultrasonic Smart Multisensor uses ultrasonic technology instead of a paddlewheel to provide accurate speed, depth and temperature via NMEA 2000. The UDST800 uses Airmar's patented adaptive signal processing to constantly calculate boat speed based on water clarity and depth to generate updated speed data, delivering it to your network up to 10 times per second.

          Features:

          • Ultrasonic depth, speed, and water-temperature sensor
          • Provides precise readings at high speeds - ideal for powerboats, cruising, and sailing
          • 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
          • 235 kHz frequency prevents interference with other echosounders on the vessel
          • 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 P617V, B617V or SS617V housings
          • Includes Ultrasonic processer and blanking plug

          Rated 4 out of 5 by from Works well but can’t be calibrated by Raymarine After installing, my Raymarine Lighthouse 4 software immediately recognized and displayed all data from the new unit even though my prior Airmar 800DST was still connected (but no longer in the through hull). The only problem is that I can not adjust the offset for the depth sounder or calibrate the speed. Luckily the speed seems very accurate. I adjusted my depth alarm to compensate for the lack of offset and will slowly get used to the new readings. The 850 series apparently has Bluetooth and can be calibrated via Airmar app. Something to consider.
