The Garmin Airmar DST 810 is a plastic thru-hull NMEA 2000 smart transducer engineered to deliver depth, speed, and temperature data alongside attitude sensing for heel/trim and pitch/roll. Operating at 235 kHz, it minimizes mutual interference with other echosounders aboard and reads bottom to 300 feet. A 5 Hz water speed output keeps speed readouts smooth on compatible chartplotters and displays. The wide 10x44-degree fan-shaped beam reliably finds bottom on steep deadrise hulls and heeling sailboats, while built-in Bluetooth connectivity pairs with the Airmar Cast app for straightforward sensor calibration management.
