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.\n\u003c\/p\u003e\n\n\u003ch3\u003eMeasurements and Performance\u003c\/h3\u003e\n\u003cp\u003e\n    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.\n\u003c\/p\u003e\n\n\u003ch3\u003eConnectivity and Calibration\u003c\/h3\u003e\n\u003cp\u003e\n    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.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation and Safety\u003c\/h3\u003e\n\u003cp\u003e\n    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.\n\u003c\/p\u003e","brand":"Raymarine","offers":[{"title":"Default Title","offer_id":57339213283668,"sku":"T70627","price":399.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/0w1oz1vw_raymarine-E70730-official.jpg?v=1793722474","url":"https:\/\/skysat.fr\/en-tr\/products\/raymarine-capteur-dst820-profondeur-vitesse-temperature-seatalkng","provider":"Skysat","version":"1.0","type":"link"}
