This model integrates a Gen2 paddle wheel and Bluetooth connectivity to the Airmar CAST™ app, offering a complete solution for measuring depth, speed through water, temperature, and boat attitude.\n\u003c\/p\u003e\n\u003ch3\u003eSpeed and depth performance\u003c\/h3\u003e\n\u003cp\u003e\n    The DST820 stands out with its Gen2 paddle wheel, which ensures speed through water responsiveness from 0.3 knots and linearity from 0.6 knots, maintaining accuracy up to 45 knots. 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 transducer 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.\n\u003c\/p\u003e\n\u003ch3\u003eAdvanced calibration and system integration\u003c\/h3\u003e\n\u003cp\u003e\n    This sensor integrates an attitude sensor for boat heel and trim, with a nominal accuracy of +\/- 1° after calibration. This data is used for advanced calibration of heel-compensated speed, a feature previously available only via expensive PC software. The Airmar CAST™ app enables intuitive calibration and custom configurations directly from a mobile device, simplifying optimization of transducer performance. The DST820 is NMEA 2000® compatible, integrating directly into the onboard network for data transmission to instruments and multifunction displays. 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 ingress when removing the insert for maintenance.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":55860570685780,"sku":"010-11051-30","price":375.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_1561f077-ce27-4b2d-98e5-5a5614339557.png?v=1779194545","url":"https:\/\/skysat.fr\/en-bh\/products\/garmin-airmar-dst810-smart-multifunction-through-hull-sensor","provider":"Skysat","version":"1.0","type":"link"}
