The speed output is refreshed at 5.7 Hz (5 times per second), ensuring smoother data and increased responsiveness for decision-making. For depth, the sensor operates at a frequency of 235 kHz, with a minimum range of 0.5 m and a maximum range of 100 m via NMEA 2000®. Water temperature is measured with an accuracy of ±0.5°C over a range of -10°C to 40°C.

Advanced calibration and system integration

This sensor integrates an attitude sensor for heel and trim, with a nominal accuracy of +/- 1° after calibration. This data is used for advanced heel-compensated speed calibration, a feature previously available only through expensive PC software. The Airmar CAST™ app enables intuitive calibration and custom configurations directly from a mobile device, facilitating optimization of the sensor's performance. The DST810 is NMEA 2000® compatible, integrating directly into the onboard network for data transmission to multifunction displays and instruments. It can replace existing DT800 or DST800 transducers, using the same through-hull fitting, which simplifies equipment upgrades. Its housing features a self-sealing valve, minimizing water entry when removing the insert for maintenance.

« The Airmar DST810 transducer: precision and simplified calibration for your NMEA 2000 network »

The Garmin Airmar DST810 intelligent transducer represents a significant advance for navigators seeking accurate data acquisition and simplified calibration. Its key asset is the integration of the Gen2 paddlewheel, delivering exceptional speed accuracy, particularly at low speeds (from 0.3 knots), which is crucial for sailboats or trolling fishing boats. This ability to provide reliable data from the slightest movements is a distinct advantage over previous-generation sensors.

The Airmar CAST™ app is a key element of this transducer's added value. It turns the complexity of calibration into an intuitive task that can be performed from a smartphone or tablet. The ability to perform speed calibrations compensated for heel, across multiple angles and up to 10 speeds, optimizes speed display performance, particularly for racing sailboats where heel can skew readings. This eliminates the need for often costly and complex PC software.

In terms of installation, the through-hull format with a self-sealing valve simplifies maintenance without requiring the boat to be ashore. While a through-hull installation requires drilling the hull, NMEA 2000® connectivity ensures simple and direct electrical integration into the existing network. The integrated attitude sensor provides valuable data for autopilot systems or performance displays, enabling refined navigation strategies. This model is particularly suited to pleasure boats, sailboats, and small motorboats seeking a reliable "all-in-one" solution that is easy to configure, without the constraints of multi-sensor systems. It represents an excellent upgrade for users of older DST800 or DT800 transducers.
