Airmar DST810 nutik sond

The Airmar DST810 smart transducer is a multifunction sensor designed to measure and provide the following data:

Depth below the hull.Speed through the water.Water temperature.Boat attitude (heel and trim).

The DST810 depth sounder is equipped with second-generation (Gen2) paddlewheel technology. This design delivers improved performance, including speed responsiveness from 0.3 knots and linearity from 0.6 knots, while maintaining accuracy up to 45 knots.

The DST810 transducer can accurately measure water speed over a range from 0.3 knots to 45 knots. Data linearity is ensured from 0.6 knots onwards.

Speed through the water data is refreshed at a rate of 5.7 Hz, or 5 times per second. This ensures smoother display and more responsive data for better decision-making.

The DST810 transducer operates at a frequency of 235 kHz and can measure a minimum depth of 0.5 meters (1.6 feet) and a maximum depth up to 100 meters (330 feet) via NMEA 2000®.

The DST810 depth sounder’s water temperature sensor has an accuracy of ±0.5°C (±1.8°F) over a measurement range from -10°C to 40°C.

Yes, the DST810 transducer includes an attitude sensor that provides heel and trim data. The nominal accuracy of these data is ±1° after calibration.

The DST810 depth sounder uses the Bluetooth Low Energy (BLE) protocol for its wireless connectivity. This allows it to connect to the Airmar CAST™ application for calibration and data visualization.

The DST810 transducer is supplied with a standard 6-metre (20-foot) DeviceNet cable, NMEA 2000® compatible.

Yes, the DST810 transducer’s innovative housing design includes a self-sealing valve. This valve is designed to minimize water ingress into the boat when the transducer insert is removed, for example during maintenance.

The Airmar DST810 transducer is fully compatible with electronic systems using the NMEA 2000® network. It transmits all its data (depth, speed, temperature, attitude) via this standard protocol.

The compatibility of the DST810 transducer with the hull type depends on the material of its housing:

A plastic housing is recommended for fiberglass or metal hulls only. It must never be installed in a wooden hull.A bronze housing is recommended for fiberglass or wooden hulls. It must never be mounted in a metal hull.A stainless steel housing is compatible with all hull materials. For a metal hull, it is recommended to use the provided isolation ring to prevent electrolytic corrosion.

The Airmar CAST™ application is designed for use on iOS or Android mobile devices with Bluetooth® connectivity. You can download it from the App Store or Google Play Store.

The DST810 transducer can be installed on hulls with a deadrise angle up to 22°. However, for optimal performance, it is recommended to select a location with a deadrise angle through 7°.

No, it is strongly discouraged to install a DST810 transducer with a metal housing (bronze or stainless steel) on a vessel equipped with a positive grounding system. This could cause electrolytic corrosion.

When installing the transducer, it is imperative to wear personal protective equipment:

Safety glasses.Dust mask.Hearing protection.

Yes, antifouling paint must be applied to all water-exposed surfaces of the depth sounder. Use only water-based antifouling paint designed for transducers. Never use ketone-based paint, as it can damage the sensor's plastic parts.

During installation, the arrow on the top of the transducer insert must point forward, toward the bow of the boat, to align the sensor correctly with the water flow.

To establish a Bluetooth® connection with the Airmar CAST™ app on a mobile device, the DST810 transducer must be within a maximum distance of 5 meters (16 feet) from the device.

Yes, to ensure optimal performance, avoid mounting the depth sounder in the following areas:

In line with or near water intakes or outlets.Behind strakes, fittings, or hull irregularities that could disrupt water flow.In areas where the transducer beam could be obstructed by the keel or propeller shaft.Near sources of electrical interference or radiation (propellers, engines, other fishfinders, cables).
