Detailed description

The Raymarine DST820 0° through-hull multifunction transducer provides essential depth, speed through water (STW), water temperature, and boat heel/pitch data. Designed for seamless integration into modern navigation systems, this transducer incorporates Airmar’s Gen2 paddlewheel technology for precise and responsive speed measurement, complemented by NMEA 2000 and Bluetooth® Low Energy connectivity.

Measurements and Performance

The DST820 measures depth at 235 kHz, offering a range from 0.5 m to 100 m with a refresh rate of once per second. For speed, the Gen2 paddlewheel delivers detection from 0.3 knots, linear accuracy from 0.6 knots, and stable readings up to 45 knots, with a 5.7 Hz output rate for smoother display. Water temperature is measured with ±0.5°C accuracy across a range of -10°C to 40°C. An integrated attitude sensor provides heel and pitch data with a nominal accuracy of ±1° after calibration, at a refresh rate of 10 times per second.

Connectivity and Calibration

This transducer features an NMEA 2000 (DeviceNet) interface with a standard 6 m cable and ships with a SeaTalkNG adapter for extended compatibility with Raymarine instruments. Bluetooth® Low Energy connectivity enables wireless calibration via the Airmar CAST™ mobile app. This app simplifies heel-compensated speed calibration (across multiple angles and up to 10 speeds), offset configuration, and attitude calibration—formerly achievable only with expensive PC software. The DST820 stores these calibrations and configurations internally.

Installation and Safety

Its P617V housing includes a self-sealing valve to minimize water ingress when removing the insert. The transducer operates on 9 VDC to 16 VDC, consuming less than 200 mA. It complies with UK PSTI safety standards, offering secure configuration via QR code and a unique password.

Expert opinion

« DST820 Raymarine: the 4-in-1 multifunction sensor for performance and safety »

The Raymarine DST820 transducer is a strategic component for any navigation system, providing a set of fundamental data from a single through-hull sensor. Its ability to measure depth, speed through the water, temperature, and attitude (heel and trim) makes it particularly relevant for cruising and racing sailboats, where precise knowledge of the boat's behavior and its environment is crucial. Heel and trim data can be used to refine polar diagrams, optimize sail trim, or compensate other instruments.

The physical installation as a through-hull sensor requires a 51 mm hole, which is a standard operation but must be carried out carefully. The inclusion of a SeaTalkNG adapter is an advantage for owners of existing Raymarine systems, facilitating connection to the network without requiring additional interfaces.

Compliance with PSTI safety standards also adds an extra layer of confidence in the network data. This sensor represents a reliable and modern 4-in-1 solution, offering significant added value for a wide range of vessels, from coastal cruising to amateur regattas.

Frequently Asked Questions

Need help? Contact us

What are the main functions of the Raymarine DST820 transducer?

The Raymarine DST820 sensor is a smart multi-sensor that measures depth, speed through the water, water temperature, and also provides attitude data (heel and trim) of your boat.

Which communication protocol does the DST820 sensor use to connect to other instruments?

The DST820 sensor uses the NMEA 2000® protocol for communication with other instruments in your onboard network. It is supplied with a SeaTalkNG adapter for easy integration with Raymarine systems.

Which paddlewheel technology is used in the DST820 sensor and what is its accuracy?

The DST820 transducer integrates Airmar’s Gen2 high-performance impeller. This technology delivers unmatched speed accuracy, with precise start-up data from 0.3 knots, linear accuracy from 0.6 knots, and stable readings up to 45 knots.

What is the depth measurement range of the DST820 transducer?

The DST820 transducer can track depth from 0.5 metres (1.6 feet) up to 100 metres (328 feet).

How does the DST820 sensor measure the boat's attitude (heel and trim)?

The DST820 transducer is equipped with an integrated attitude sensor that provides heel and trim data. This information is used notably for advanced calibration of heeled-speed data.

Which mobile app is used to calibrate the DST820 transducer, and what are its features?

The DST820 transducer connects via secure Bluetooth® to the free Airmar CAST™ app. This app allows you to calibrate speed in a simple and intuitive way, perform basic or advanced speed calibrations compensated for heel, and configure attitude offsets.

Does the DST820 transducer offer network security features for the onboard system?

Yes, the DST820 fully complies with UK PSTI safety standards, ensuring a secure connection between the sensor and a mobile device. Configuration is done via a secure QR code and a unique password.

How frequently are speed, depth, and attitude data updated by the sensor?

Depth: 1 time per secondSpeed: 5 times per second (5.7 Hz)Heel/Trim: 10 times per second

What is the standard cable length of the DST820 transducer and what type of connector does it use?

The DST820 transducer is supplied with a standard 6 m (20 ft) DeviceNet cable, NMEA 2000® compatible.

What is the water temperature range that the DST820 sensor can measure?

The DST820 sensor can measure water temperature in a range from -10°C to 40°C (14°F to 104°F).

What is the current draw of the DST820 transducer?

The DST820 transducer has a current draw of less than 200 mA, in accordance with NMEA 2000® specifications.

What is the housing material of the DST820 sensor and what is its weight?

The DST820 sensor is available in different versions (plastic, bronze, stainless steel). The version offered (T70627) is plastic and weighs approximately 0.9 kg. The plastic housing is type P617V.

What is the required supply voltage for the DST820 transducer?
