It is the next evolution of Airmar's industry-leading technology, replacing the DST810 and introducing UK PSTI compliance for enhanced onboard network security via secure QR-code Bluetooth pairing.\u003c\/p\u003e\r\n\u003cp\u003eIt can read depths to 100 m (330 ft) and offers fast 5 Hz water speed signal output for smoother visualisation on compatible chartplotters or other displays. At its heart is Airmar's Gen2 paddlewheel, which delivers start-up speed from as low as 0.3 knots, becomes linear at 0.6 knots and stays accurate up to 45 knots. An integrated attitude sensor adds heel\/trim and pitch\/roll data, while Bluetooth Low Energy connectivity links the sensor to the free Airmar CAST app for intuitive, heel-compensated speed calibration. The 235 kHz frequency helps prevent interference with other onboard echosounders, and the wide 10 x 44 degree beam holds bottom lock even on steep deadrise hulls and heeling sailboats. The low-profile plastic housing incorporates a self-closing valve and fits hull deadrise up to 22 degrees.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":57332710408532,"sku":"010-11051-30","price":430.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/9702\/3060\/files\/cf-lg.jpg?v=1790692034","url":"https:\/\/hudsonmarine.co.uk\/products\/garmin-airmar-dst820-smart-transducer-010-11051-30","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
