Detailed description

Designed for sailboats and powerboats, the AIRMAR DST810 multisensor transducer provides depth, speed through water, and temperature data, enhanced by boat attitude information via NMEA 2000. This through-hull transducer integrates Bluetooth Low Energy (BLE) wireless connectivity for advanced calibration and simplified configuration.

Technical Features and Performance

The DST810 operates at 235 kHz, helping to prevent interference with other depth sounders on board. It delivers depth measurements up to 100 meters via NMEA 2000, with a minimum range of 0.5 meters and data updates once per second. Speed through water is measured from 0.3 to 45 knots. With a refresh rate of 5.7 Hz, speed readings are visibly smoother and more responsive. The water temperature sensor operates from -10°C to 40°C with an accuracy of ±0.5°C.

Innovation and Advanced Calibration

The integrated attitude sensor for heel and trim, with a nominal accuracy of +/- 1° after calibration, enables advanced speed corrections. This feature, combined with the AIRMAR CAST™ app via Bluetooth, offers heel-compensated speed calibration across multiple angles and speed ranges (up to 10 speeds). Previously limited to expensive PC software, this capability is now accessible via a mobile device. All speed calibrations and NMEA configurations are stored directly in the DST810 sensor, ensuring independence from onboard instruments.

Design and System Integration

The DST810 uses a Gen2 paddlewheel for responsive speed performance, providing ultra-responsive readings from 0.3 knots and linearity at 0.6 knots. Its 10 x 44-degree fan beam is designed to maintain a stable bottom lock on deep-keel hulls or heeling sailboats, and is compatible with hull inclinations up to 22°. Power is supplied via the NMEA 2000 network (9 VDC to 16 VDC, drawing less than 200 mA). The sensor ships with a 6-meter DeviceNet cable. Compared to simpler NMEA 2000 transducers from the same brand or competitors, the DST810 is an advanced all-in-one solution, eliminating the need for separate attitude sensors and simplifying complex calibration via its wireless interface.

« Technical analysis of the AIRMAR DST810 NMEA 2000 sensor »

The AIRMAR DST810 transducer represents a significant evolution for modern navigation systems, particularly for recreational sailors and racers looking to optimize their instrumentation performance. Its ability to combine depth, speed, temperature, and attitude (heel/trim) data in a single through-hull unit greatly simplifies installation compared to multi-sensor setups.

The integration of the attitude sensor is a major asset, enabling heel-compensated speed calibration. This feature, accessible via the AIRMAR CAST™ app via Bluetooth, democratizes high-precision adjustments that were previously limited to complex professional systems. For a sailboat, this means more reliable and usable true speed readings, regardless of heel conditions. For a powerboat, speed and fuel consumption optimization can be refined with better knowledge of attitude.

This transducer is particularly suited to mid-sized vessels (8 to 15 meters) where space for hull penetrations is limited, and where data precision is sought without the complexity of multiple sensors. It is less relevant for very large ships requiring multiple sounder frequencies or high-end dedicated attitude sensors, or for small tenders where a simple depth sensor may suffice. Installation requires a standard hull penetration and connection to an existing NMEA 2000 network, which is relatively straightforward for a qualified installer. Maintenance is simplified by the ability to remove the paddle wheel for cleaning thanks to the valve-equipped through-hull body.
