The Garmin Airmar DST820 Smart is a versatile through-beam transducer that measures depth, water speed and water temperature with a single sensor. The built-in motion sensor also provides information on the boat's pitch, trim, and pitch and roll.
The DST820 is particularly well suited for sailboats and other vessels where accurate and fast-updating speed information is important. Speed ??information updates at a frequency of 5 Hz, allowing for consistent speed display on compatible chartplotters and gauges.
The sensor is connected to the boat's NMEA 2000 network. Thanks to the Bluetooth connection, the sensor data can be calibrated using the Airmar CAST app.
The 235 kHz operating frequency helps reduce the risk of interference from other sonar devices on the boat. The wide, fan-shaped 10 x 44 degree beam makes it easy to detect the bottom, even when the transducer is mounted on a hull with a higher draft angle or on a sailboat that lists while sailing.
